* This software was written by Jim Fougeron jfoug AT cox dot net

*
* This software may be modified, redistributed, and used for any
* purpose, in source and binary forms, with or without modification.
*
* Format was busted, just like wow-srp. It ONLY was handling binary residue
* if the residue was exactly 64 hex bytes long. Well for exponentation, it
* does not have to be 64 bytes. It can be shorter. We also handle case where
* a shorter result number is 0 Lpadded to an even 64 bytes. split() should
* be added to canonize these hashes, since they are same hash with
* multiple representations.
*
* This implements the SRP protocol, with Clipperz documented
* implementation specifics.
*
* s = random salt value.
*
* v is the 'verifier' value (256 bit value).
*
* Clipperz's offline database has following relevant fields,
*
* <script>_clipperz_dump_data_ = { ...
*
* '2f2134e38b23534adfcd43c2f7223caf3a53a8db7ce800f1e918e8e0d06b8b7a': {
* s: 'e0bc11ee4db80a3ecabd293f5201cb747856361192c68f4133ea707c7d4d2d32',

* version: '0.2',
* ...
* }
* P algorithm:
* h1 = hashlib.sha256(password + username).digest()
* P = h2 = hashlib.sha256(h1).hexdigest()
*
* x algorithm:
* x1 = hashlib.sha256(s + P).digest()
* x = hashlib.sha256(x1).hexdigest()

/*
Two pointers have distance of 12 (p1 - p2 = 12).
They are used as base addresses for indirect array accesses using an index set (another array).
An index set has two indices with distance of 12 :
indexSet[3]- indexSet[0] = 533 - 521 = 12
So there is loop carried dependence for N=0 and N=3.
We use the default loop scheduling (static even) in OpenMP.
It is possible that two dependent iterations will be scheduled
within a same chunk to a same thread. So there is no runtime data races.
N is 180, two iteraions with N=0 and N= 3 have loop carried dependences.
For static even scheduling, we must have at least 60 threads (180/60=3 iterations)
so iteration 0 and 3 will be scheduled to two different threads.
Data race pair: xa1[idx]@128:5 vs. xa2[idx]@129:5

// This allocator can be used with STL containers to provide a stack buffer
// from which to allocate memory and overflows onto the heap. This stack buffer
// would be allocated on the stack and allows us to avoid heap operations in
// some situations.
//
// STL likes to make copies of allocators, so the allocator itself can't hold
// the data. Instead, we make the creator responsible for creating a
// StackAllocator::Source which contains the data. Copying the allocator
// merely copies the pointer to this shared source, so all allocators created
// based on our allocator will share the same stack buffer.
//
// This stack buffer implementation is very simple. The first allocation that
// fits in the stack buffer will use the stack buffer. Any subsequent
// allocations will not use the stack buffer, even if there is unused room.
// This makes it appropriate for array-like containers, but the caller should
// be sure to reserve() in the container up to the stack buffer size. Otherwise
// the container will allocate a small array which will "use up" the stack
// buffer.

MCarloX.c | /*
Project: mpi_monte_carlo
File: mpi_monte_carlo.cpp
Created By: James Williams
Date: 11/14/15.
Purpose: Estimate Pi by simulation of throwing darts at a dart board.
Program will use MPI for distributed computing across nodes.
1. Process 0 should read in the total number of tosses and
broadcast it to the other processes.
2. Use MPI Reduce to find the global sum of the local variable number
in circle, and have process 0 print the result.
Note: num_darts was somehow being altered mid program, so the variable
was reset to the original number of darts to be thrown right
before process 0 calculates pi.
Compile: mpicc MCarloX.c -fopenmp -o MCarloX
Usage: mpiexec -n <# nodes or processors> MPI_MCarlo

* Example program for IDAS: Food web problem, OpenMP, GMRES,
* user-supplied preconditioner
*
* This example program uses SUNLinSol_SPGMR as the linear
* solver, and IDACalcIC for initial condition calculation.
*
* The mathematical problem solved in this example is a DAE system
* that arises from a system of partial differential equations after
* spatial discretization. The PDE system is a food web population
* model, with predator-prey interaction and diffusion on the unit
* square in two dimensions. The dependent variable vector is:
*
* 1 2 ns
* c = (c , c , ..., c ) , ns = 2 * np
*
* and the PDE's are as follows:
*
* i i i
* dc /dt = d(i)*(c + c ) + R (x,y,c) (i = 1,...,np)
* xx yy i
*
* i i
* 0 = d(i)*(c + c ) + R (x,y,c) (i = np+1,...,ns)
* xx yy i
*
* where the reaction terms R are:
*
* i ns j
* R (x,y,c) = c * (b(i) + sum a(i,j)*c )
* i j=1
*
* The number of species is ns = 2 * np, with the first np being
* prey and the last np being predators. The coefficients a(i,j),
* b(i), d(i) are:
*
* a(i,i) = -AA (all i)
* a(i,j) = -GG (i <= np , j > np)
* a(i,j) = EE (i > np, j <= np)
* all other a(i,j) = 0
* b(i) = BB*(1+ alpha * x*y + beta*sin(4 pi x)*sin(4 pi y)) (i <= np)
* b(i) =-BB*(1+ alpha * x*y + beta*sin(4 pi x)*sin(4 pi y)) (i > np)
* d(i) = DPREY (i <= np)
* d(i) = DPRED (i > np)
*
* The various scalar parameters required are set using '#define'
* statements or directly in routine InitUserData. In this program,
* np = 1, ns = 2. The boundary conditions are homogeneous Neumann:
* normal derivative = 0.
*
* A polynomial in x and y is used to set the initial values of the
* first np variables (the prey variables) at each x,y location,
* while initial values for the remaining (predator) variables are
* set to a flat value, which is corrected by IDACalcIC.
*
* The PDEs are discretized by central differencing on a MX by MY
* mesh.
*
* The DAE system is solved by IDAS using the SUNLinSol_SPGMR linear solver.
* Output is printed at t = 0, .001, .01, .1, .4, .7, 1.
*
* Optionally, we can set the number of threads from environment
* variable or command line. To check the current value for number
* of threads from environment:
* % echo $OMP_NUM_THREADS
*
* Execution:
*
* To use the default value for the number of threads from
* the OMP_NUM_THREADS environment value:
* % ./idasFoodWeb_kry_omp
* To specify the number of threads at the command line, use
* % ./idasFoodWeb_kry_omp num_threads
* where num_threads is the desired number of threads.

OpenMP-3.0 Example Codes Beta-v1.0
File : tree-traverse-alg-openmp3x.c
Date : Aug 2011
Description : The example program demonstrate the use of openmp new feature
task construct to perform the parallelization of hierarchical
algorithum (inorder tree traversal) and compare it with the
openmp-2.5 approach using single construct & dispaly the
time taken in both approcahes
a) inorderTraverse_Task() :Uses OpenMP-3.0 Task Construct which is an
efficient approah. Whenever a thread encounters a task construct,
a new explicit task, An explicit task may be executed by any thread
in the current team, in parallel with other tasks.In this approach the
several task can be executed in parallel.
b) inorderTraverse_Wtask() : Uses OpenMP-2.5 parallel - section directive.
whenever a thread encounter the parallel region it creates the team of
threads. When the thread in a team encounter the section directive it
execute the section region.This approach can be costly, however, because
of the overhead of parallel region creation, the risk of oversubscribing
system resources, difficulties in load balancing, and different behaviors
of different implementations
OpenMP pragma/
Directive used : #pragma omp parallel
#pragma omp section
#pragma omp task
Input : - Number of Nodes in the link list
- Number of threads to be used

// A leap frog method is used to assure non-overlapping

// Note: these functions are to be called from inside the

//
// BACKGROUND:
//
// We are using a modulus of 2^31-1 and a multiplier from
// the Hoaglin LCGs in the following article:
//
// http://random.mat.sbg.ac.at/~charly/server/node3.html#lcg
//
// we are using a zero addend just to make the leap frog
// algorithm easier to implement.
