NAME: RandomAccess
PURPOSE: This program tests the efficiency of the memory subsystem to
update elements of an array with irregular stride.
USAGE: The program takes as input the number of threads involved, the 2log
of the size of the table that gets updated, the ratio of table size
over number of updates, and the vector length of simultaneously
updatable table elements. When multiple threads participate, they
all share the same table. This can lead to conflicts in memory
accesses. Setting the ATOMICFLAG variable in the Makefile will
avoid conflicts, but at a large price, because the atomic
directive is currently not implemented on IA for the type of update
operation used here. Instead, a critical section is used, serializing
the main loop.
If the CHUNKFLAG variable is set, contiguous, non-overlapping chunks
of the array are assigned to individual threads. Each thread computes
all pseudo-random indices into the table, but only updates table
elements that fall inside its chunk. Hence, this version is safe, and
there is no false sharing. It is also non-scalable.
<progname> <# threads> <log2 tablesize> <#update ratio> <vector length>
FUNCTIONS CALLED:
Other than OpenMP or standard C functions, the following
functions are used in this program:
wtime()
bail_out()
PRK_starts()
poweroftwo()
NOTES: This program is derived from HPC Challenge Random Access. The random
number generator computes successive powers of 0x2, modulo the
primitive polynomial x^63+x^2+x+1. The principal differences between
this code and the HPCC version are:
- we start the stream of random numbers not with seed 0x1, but the
SEQSEED-th element in the stream of powers of 0x2.
- the timed code applies the RandomAccess operator twice to the table of
computed resuls (starting with the same seed(s) for "ran" in both
iterations. The second pass makes sure that any update to any table
element that sets high-order bits in the first pass resets those bits
to zero.
- the verification test now simply constitutes checking whether table
element j equals j.
- the number of independent streams (vector length) can be changed by the
user.
We note that the vectorized version of this code (i.e. nstarts unequal
to 1), does not feature exactly the same sequence of accesses and
intermediate update values in the table as the scalar version. The
reason for this is twofold.
1. the elements in the stream of powers of 0x2 that get computed outside
the main timed loop as seeds for independent streams in the vectorized
version, using the jump-ahead function PRK_starts, are computed inside
the timed loop for the scalar version. However, since both versions do
the same number of timed random accesses, the vectorized version must
progress further in the sequence of powers of 0x2.
2. The independent streams of powers of 0x2 computed in the vectorized
version can (and will) cause updates of the same elements of the table
in an order that is not consistent with the scalar version. That is,
distinct values of "ran" can refer to the same table element
"ran&(tablesize-1)," but the operation
Table[ran&(tablesize-1)] ^= ran will deposit different values in that
table element for different values of ran. At the end of each pass over
the data set, the table will contain the same values in the vector and
scalar version (ignoring the small differences caused by 1.) because of
commutativity of the XOR operator. If the update operator had been
non-commutative, the vector and scalar version would have yielded
different results.

//Student ID: 21804416
//Name: SUN QIANG
//Where use openmp speed up:
//Here we have four tasks using openmp to speed up
//1. use openmp to sort all columns
//2. use openmp to generate blocks
//3. The key point here, use openmp to sort all the signtures(29333879), the openmp speed up is very useful here
// At first, I can not sort 29333879 signtures with my computer using only one thread, always core down
// Then, when I use openmp here, then problem solved.
//4. Divide sorted signatures with different parts, and find collisions with openmp
//Where still need speed up
//There are still some problems we can do to speed up:
//The last column(500), generated 29321366 signtures, and the left 499 colunms generated 12510 signtures
// So when we find blocks, most time spent on find blocks in 500 columns with one thread, the other threads are idle.
// However, the time spent to find the blocks in 500 colunm is not very long;
// And we need to keep this program working for any M*N matrix, so I have not done any improvement here.
// we can change the N & M to make this program suitable for some other N*M matrix
// we can change the dia to other value
// Change the Max value if the number of blocks is larger than that
#define N 500
#define M 4400
#define dia 0.000001
#define Max 30000000
// ---------
// The data array to store the data information
// The key array to store key information
// When we want to sort values in each column in data, we only need to sort the seq array to store the sequences
// Location of data value, not directly modify the data array.
// Signs array to store the signtures for blocks
// Location array to store the row ids and column for corresponding signture, for example 434044402220999499 means
// The block combined by 434,444,222,999 rows from 499 column.
// Indexs to store how many blocks generated
// Id is the same function as the seq array, to store the location information of the signture
//----------
//readData() and readkey() to read values from txt, generate two arrays
// Generate() is to generate the seq array
// sort() is to sort each column in data
// SelectSort() Bubblesort() are used to sort the values (we can use some other methods)
// Findblock() and findblockcol() are used to generate columns
//Sortsign() and BubbleSortsign() are single thread ways to sort the signtures.
// quicksort() is the method which use multiple threads with openmp to sort the signtures based on quicksort.
// resulttxt() is used to print the outcome with two colunm (signture,id)

/* miniz.c v1.15 - public domain deflate/inflate, zlib-subset, ZIP
reading/writing/appending, PNG writing
See "unlicense" statement at the end of this file.
Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13, 2013
Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951:
http://www.ietf.org/rfc/rfc1951.txt
Most API's defined in miniz.c are optional. For example, to disable the
archive related functions just define
MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO
(see the list below for more macros).
* Change History
10/13/13 v1.15 r4 - Interim bugfix release while I work on the next major
release with Zip64 support (almost there!):
- Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug
(thanks kahmyong.moon@hp.com) which could cause locate files to not find
files. This bug
would only have occured in earlier versions if you explicitly used this
flag, OR if you used mz_zip_extract_archive_file_to_heap() or
mz_zip_add_mem_to_archive_file_in_place()
(which used this flag). If you can't switch to v1.15 but want to fix
this bug, just remove the uses of this flag from both helper funcs (and of
course don't use the flag).
- Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when
pUser_read_buf is not NULL and compressed size is > uncompressed size
- Fixing mz_zip_reader_extract_*() funcs so they don't try to extract
compressed data from directory entries, to account for weird zipfiles which
contain zero-size compressed data on dir entries.
Hopefully this fix won't cause any issues on weird zip archives,
because it assumes the low 16-bits of zip external attributes are DOS
attributes (which I believe they always are in practice).
- Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the
internal attributes, just the filename and external attributes
- mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed
- Added cmake support for Linux builds which builds all the examples,
tested with clang v3.3 and gcc v4.6.
- Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti
- Merged MZ_FORCEINLINE fix from hdeanclark
- Fix <time.h> include before config #ifdef, thanks emil.brink
- Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping
(super useful for OpenGL apps), and explicit control over the compression
level (so you can
set it to 1 for real-time compression).
- Merged in some compiler fixes from paulharris's github repro.
- Retested this build under Windows (VS 2010, including static analysis),
tcc 0.9.26, gcc v4.6 and clang v3.3.
- Added example6.c, which dumps an image of the mandelbrot set to a PNG
file.
- Modified example2 to help test the
MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more.
- In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix
possible src file fclose() leak if alignment bytes+local header file write
faiiled
- In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader():
Was pushing the wrong central dir header offset, appears harmless in this
release, but it became a problem in the zip64 branch
5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE,
#include <time.h> (thanks fermtect).
5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix
mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit.
- Temporarily/locally slammed in "typedef unsigned long mz_ulong" and
re-ran a randomized regression test on ~500k files.
- Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
- Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze
(static analysis) option and fixed all warnings (except for the silly
"Use of the comma-operator in a tested expression.." analysis warning,
which I purposely use to work around a MSVC compiler warning).
- Created 32-bit and 64-bit Codeblocks projects/workspace. Built and
tested Linux executables. The codeblocks workspace is compatible with
Linux+Win32/x64.
- Added miniz_tester solution/project, which is a useful little app
derived from LZHAM's tester app that I use as part of the regression test.
- Ran miniz.c and tinfl.c through another series of regression testing on
~500,000 files and archives.
- Modified example5.c so it purposely disables a bunch of high-level
functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the
MINIZ_NO_STDIO bug report.)
- Fix ftell() usage in examples so they exit with an error on files which
are too large (a limitation of the examples, not miniz itself).
4/12/12 v1.12 - More comments, added low-level example5.c, fixed a couple
minor level_and_flags issues in the archive API's.
level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce
Dawson <bruced@valvesoftware.com> for the feedback/bug report.
5/28/11 v1.11 - Added statement from unlicense.org
5/27/11 v1.10 - Substantial compressor optimizations:
- Level 1 is now ~4x faster than before. The L1 compressor's throughput
now varies between 70-110MB/sec. on a
- Core i7 (actual throughput varies depending on the type of data, and x64
vs. x86).
- Improved baseline L2-L9 compression perf. Also, greatly improved
compression perf. issues on some file types.
- Refactored the compression code for better readability and
maintainability.
- Added level 10 compression level (L10 has slightly better ratio than
level 9, but could have a potentially large
drop in throughput on some files).
5/15/11 v1.09 - Initial stable release.
* Low-level Deflate/Inflate implementation notes:
Compression: Use the "tdefl" API's. The compressor supports raw, static,
and dynamic blocks, lazy or
greedy parsing, match length filtering, RLE-only, and Huffman-only streams.
It performs and compresses
approximately as well as zlib.
Decompression: Use the "tinfl" API's. The entire decompressor is
implemented as a single function
coroutine: see tinfl_decompress(). It supports decompression into a 32KB
(or larger power of 2) wrapping buffer, or into a memory
block large enough to hold the entire file.
The low-level tdefl/tinfl API's do not make any use of dynamic memory
allocation.
* zlib-style API notes:
miniz.c implements a fairly large subset of zlib. There's enough
functionality present for it to be a drop-in
zlib replacement in many apps:
The z_stream struct, optional memory allocation callbacks
deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
inflateInit/inflateInit2/inflate/inflateEnd
compress, compress2, compressBound, uncompress
CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly
routines.
Supports raw deflate streams or standard zlib streams with adler-32
checking.
Limitations:
The callback API's are not implemented yet. No support for gzip headers or
zlib static dictionaries.
I've tried to closely emulate zlib's various flavors of stream flushing
and return status codes, but
there are no guarantees that miniz.c pulls this off perfectly.
* PNG writing: See the tdefl_write_image_to_png_file_in_memory() function,
originally written by
Alex Evans. Supports 1-4 bytes/pixel images.
* ZIP archive API notes:
The ZIP archive API's where designed with simplicity and efficiency in
mind, with just enough abstraction to
get the job done with minimal fuss. There are simple API's to retrieve file
information, read files from
existing archives, create new archives, append new files to existing
archives, or clone archive data from
one archive to another. It supports archives located in memory or the heap,
on disk (using stdio.h),
or you can specify custom file read/write callbacks.
- Archive reading: Just call this function to read a single file from a
disk archive:
void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const
char *pArchive_name,
size_t *pSize, mz_uint zip_flags);
For more complex cases, use the "mz_zip_reader" functions. Upon opening an
archive, the entire central
directory is located and read as-is into memory, and subsequent file access
only occurs when reading individual files.
- Archives file scanning: The simple way is to use this function to scan a
loaded archive for a specific file:
int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName,
const char *pComment, mz_uint flags);
The locate operation can optionally check file comments too, which (as one
example) can be used to identify
multiple versions of the same file in an archive. This function uses a
simple linear search through the central
directory, so it's not very fast.
Alternately, you can iterate through all the files in an archive (using
mz_zip_reader_get_num_files()) and
retrieve detailed info on each file by calling mz_zip_reader_file_stat().
- Archive creation: Use the "mz_zip_writer" functions. The ZIP writer
immediately writes compressed file data
to disk and builds an exact image of the central directory in memory. The
central directory image is written
all at once at the end of the archive file when the archive is finalized.
The archive writer can optionally align each file's local header and file
data to any power of 2 alignment,
which can be useful when the archive will be read from optical media. Also,
the writer supports placing
arbitrary data blobs at the very beginning of ZIP archives. Archives
written using either feature are still
readable by any ZIP tool.
- Archive appending: The simple way to add a single file to an archive is
to call this function:
mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename,
const char *pArchive_name,
const void *pBuf, size_t buf_size, const void *pComment, mz_uint16
comment_size, mz_uint level_and_flags);
The archive will be created if it doesn't already exist, otherwise it'll be
appended to.
Note the appending is done in-place and is not an atomic operation, so if
something goes wrong
during the operation it's possible the archive could be left without a
central directory (although the local
file headers and file data will be fine, so the archive will be
recoverable).
For more complex archive modification scenarios:
1. The safest way is to use a mz_zip_reader to read the existing archive,
cloning only those bits you want to
preserve into a new archive using using the
mz_zip_writer_add_from_zip_reader() function (which compiles the
compressed file data as-is). When you're done, delete the old archive and
rename the newly written archive, and
you're done. This is safe but requires a bunch of temporary disk space or
heap memory.
2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using
mz_zip_writer_init_from_reader(),
append new files as needed, then finalize the archive which will write an
updated central directory to the
original archive. (This is basically what
mz_zip_add_mem_to_archive_file_in_place() does.) There's a
possibility that the archive's central directory could be lost with this
method if anything goes wrong, though.
- ZIP archive support limitations:
No zip64 or spanning support. Extraction functions can only handle
unencrypted, stored or deflated files.
Requires streams capable of seeking.
* This is a header file library, like stb_image.c. To get only a header file,
either cut and paste the
below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then
include miniz.c from it.
* Important: For best perf. be sure to customize the below macros for your
target platform:
#define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
#define MINIZ_LITTLE_ENDIAN 1
#define MINIZ_HAS_64BIT_REGISTERS 1
* On platforms using glibc, Be sure to "#define _LARGEFILE64_SOURCE 1" before
including miniz.c to ensure miniz
uses the 64-bit variants: fopen64(), stat64(), etc. Otherwise you won't be
able to process large files
(i.e. 32-bit stat() fails for me on files > 0x7FFFFFFF bytes).

The compiler will issue the __atomic_fetch_* built-in when possible,
otherwise it will generate the generic form of the atomic operations.
This requires temp(s) and has their address taken. The atomic processing
is smart enough to figure out when the size of an object can utilize
a lock-free version, and convert the built-in call to the appropriate
lock-free routine. The optimizers will then dispose of any temps that
are no longer required, and lock-free implementations are utilized as
long as there is target support for the required size.
If the operator is NOP_EXPR, then this is a simple assignment, and
an __atomic_store is issued to perform the assignment rather than
the above loop. */

% GetVirtualPixels() returns an immutable pixel region. If the
% region is successfully accessed, a pointer to it is returned, otherwise
% NULL is returned. The returned pointer may point to a temporary working
% copy of the pixels or it may point to the original pixels in memory.
% Performance is maximized if the selected region is part of one row, or one
% or more full rows, since there is opportunity to access the pixels in-place
% (without a copy) if the image is in memory, or in a memory-mapped file. The
% returned pointer must *never* be deallocated by the user.
%
% Pixels accessed via the returned pointer represent a simple array of type
% PixelPacket. If the image type is CMYK or the storage class is PseudoClass,
% call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to access
% the black color component or to obtain the colormap indexes (of type
% IndexPacket) corresponding to the region.
%
% If you plan to modify the pixels, use GetAuthenticPixels() instead.
%
% Note, the GetVirtualPixels() and GetAuthenticPixels() methods are not thread-
% safe. In a threaded environment, use GetCacheViewVirtualPixels() or
% GetCacheViewAuthenticPixels() instead.

% QueueAuthenticPixels() queues a mutable pixel region. If the region is
% successfully initialized a pointer to a PixelPacket array representing the
% region is returned, otherwise NULL is returned. The returned pointer may
% point to a temporary working buffer for the pixels or it may point to the
% final location of the pixels in memory.
%
% Write-only access means that any existing pixel values corresponding to
% the region are ignored. This is useful if the initial image is being
% created from scratch, or if the existing pixel values are to be
% completely replaced without need to refer to their pre-existing values.
% The application is free to read and write the pixel buffer returned by
% QueueAuthenticPixels() any way it pleases. QueueAuthenticPixels() does not
% initialize the pixel array values. Initializing pixel array values is the
% application's responsibility.
%
% Performance is maximized if the selected region is part of one row, or
% one or more full rows, since then there is opportunity to access the
% pixels in-place (without a copy) if the image is in memory, or in a
% memory-mapped file. The returned pointer must *never* be deallocated
% by the user.
%
% Pixels accessed via the returned pointer represent a simple array of type
% PixelPacket. If the image type is CMYK or the storage class is PseudoClass,
% call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to obtain
% the black color component or the colormap indexes (of type IndexPacket)
% corresponding to the region. Once the PixelPacket (and/or IndexPacket)
% array has been updated, the changes must be saved back to the underlying
% image using SyncAuthenticPixels() or they may be lost.

* This software may be modified, redistributed, and used for any

*
* This implements the SRP protocol, with Blizzard's (battlenet) documented
* implementation specifics.
*
* U = username in upper case
* P = password in upper case
* s = random salt value.
*
* x = SHA1(s . SHA1(U . ":" . P));
* v = 47^x % 112624315653284427036559548610503669920632123929604336254260115573677366691719
*
* v is the 'verifier' value (256 bit value).
*
* Added OMP. Added 'default' oSSL BigNum exponentiation.
* GMP exponentation (faster) is optional, and controlled with HAVE_LIBGMP in autoconfig.h
*
* NOTE, big fix required. The incoming binary may be 64 bytes OR LESS. It
* can also be 64 bytes (or less), and have left padded 0's. We have to adjust
* several things to handle this properly. First, valid must handle it. Then
* binary and salt both must handle this. Also, crypt must handle this. NOTE,
* the string 'could' be an odd length. If so, then only 1 byte of hex is put
* into the first binary byte. all of these problems were found once I got
* jtrts.pl working with wowsrp. There now are 2 input files for wowsrp. One
* bytes of precision, then only 61 bytes will be in the string). The other
* file left pads the numbers with 0's to an even 64 bytes long, so all are
* 64 bytes. the format MUST handle both, since at this momement, we are not
* exactly sure which type will be seen in the wild. NOTE, the byte swapped
* method (GMP) within is no longer valid, and was removed.
* NOTE, we need to add split() to canonize this format (remove LPad 0's)

taken. The atomic processing is smart enough to figure out when the
size of an object can utilize a lock-free version, and convert the
built-in call to the appropriate lock-free routine. The optimizers
will then dispose of any temps that are no longer required, and
lock-free implementations are utilized as long as there is target
support for the required size.

an __atomic_store is issued to perform the assignment rather than
the above loop.
