*
* Many thanks to Nicolas Devillard who wrote the optimized methods for finding

*
* Parallelization has been achieved using OpenMP. Using a compiler that does
* not support OpenMP, e.g. clang currently, the code should still compile and
* run serially without issue. I have tried to be explicit as possible about
* specifying which variables are private and which should be shared, although
* we never actually have any shared variables. We use firstprivate instead.
* This does mean that it is important that we never have two threads write to
* the same memory position at the same time.

the creation of the DofList and the construction of the system matrix is in this case much faster

///
/// An OpenMP canonical loop is a for-statement or range-based for-statement
/// with additional requirements that ensure that the number of iterations is
/// known before entering the loop and allow skipping to an arbitrary iteration.
/// The OMPCanonicalLoop AST node wraps a ForStmt or CXXForRangeStmt that is
/// known to fulfill OpenMP's canonical loop requirements because of being
/// associated to an OMPLoopBasedDirective. That is, the general structure is:
///
/// OMPLoopBasedDirective
/// [`- CapturedStmt ]
/// [ `- CapturedDecl]
/// ` OMPCanonicalLoop
/// `- ForStmt/CXXForRangeStmt
/// `- Stmt
///
/// One or multiple CapturedStmt/CapturedDecl pairs may be inserted by some
/// directives such as OMPParallelForDirective, but others do not need them
/// (such as OMPTileDirective). In The OMPCanonicalLoop and
/// ForStmt/CXXForRangeStmt pair is repeated for loop associated with the
/// directive. A OMPCanonicalLoop must not appear in the AST unless associated
/// with a OMPLoopBasedDirective. In an imperfectly nested loop nest, the
/// OMPCanonicalLoop may also be wrapped in a CompoundStmt:
///
/// [...]
/// ` OMPCanonicalLoop
/// `- ForStmt/CXXForRangeStmt
/// `- CompoundStmt
/// |- Leading in-between code (if any)
/// |- OMPCanonicalLoop
/// | `- ForStmt/CXXForRangeStmt
/// | `- ...
/// `- Trailing in-between code (if any)
///
/// The leading/trailing in-between code must not itself be a OMPCanonicalLoop
/// to avoid confusion which loop belongs to the nesting.
///
/// There are three different kinds of iteration variables for different
/// purposes:
/// * Loop user variable: The user-accessible variable with different value for
/// each iteration.
/// * Loop iteration variable: The variable used to identify a loop iteration;
/// for range-based for-statement, this is the hidden iterator '__begin'. For
/// other loops, it is identical to the loop user variable. Must be a
/// random-access iterator, pointer or integer type.
/// * Logical iteration counter: Normalized loop counter starting at 0 and
/// incrementing by one at each iteration. Allows abstracting over the type
/// of the loop iteration variable and is always an unsigned integer type
/// appropriate to represent the range of the loop iteration variable. Its
/// value corresponds to the logical iteration number in the OpenMP
/// specification.
///
/// This AST node provides two captured statements:
/// * The distance function which computes the number of iterations.
/// * The loop user variable function that computes the loop user variable when
/// given a logical iteration number.
///
/// These captured statements provide the link between C/C++ semantics and the
/// logical iteration counters used by the OpenMPIRBuilder which is
/// language-agnostic and therefore does not know e.g. how to advance a
/// random-access iterator. The OpenMPIRBuilder will use this information to
/// apply simd, workshare-loop, distribute, taskloop and loop directives to the
/// loop. For compatibility with the non-OpenMPIRBuilder codegen path, an
/// OMPCanonicalLoop can itself also be wrapped into the CapturedStmts of an
/// OMPLoopDirective and skipped when searching for the associated syntactical
/// loop.
///
/// Example:
/// <code>
/// std::vector<std::string> Container{1,2,3};
/// for (std::string Str : Container)
/// Body(Str);
/// </code>
/// which is syntactic sugar for approximately:
/// <code>
/// auto &&__range = Container;
/// auto __begin = std::begin(__range);
/// auto __end = std::end(__range);
/// for (; __begin != __end; ++__begin) {
/// std::String Str = *__begin;
/// Body(Str);
/// }
/// </code>
/// In this example, the loop user variable is `Str`, the loop iteration
/// variable is `__begin` of type `std::vector<std::string>::iterator` and the
/// logical iteration number type is `size_t` (unsigned version of
/// `std::vector<std::string>::iterator::difference_type` aka `ptrdiff_t`).
/// Therefore, the distance function will be
/// <code>
/// [&](size_t &Result) { Result = __end - __begin; }
/// </code>
/// and the loop variable function is
/// <code>
/// [&,__begin](std::vector<std::string>::iterator &Result, size_t Logical) {
/// Result = __begin + Logical;
/// }
/// </code>
/// The variable `__begin`, aka the loop iteration variable, is captured by
/// value because it is modified in the loop body, but both functions require
/// the initial value. The OpenMP specification explicitly leaves unspecified
/// when the loop expressions are evaluated such that a capture by reference is
/// sufficient.

% TransformImage() is a convenience method that behaves like ResizeImage() or
% CropImage() but accepts scaling and/or cropping information as a region
% geometry specification. If the operation fails, the original image handle
% is left as is.
%
% This should only be used for single images.
%
% This function destroys what it assumes to be a single image list.
% If the input image is part of a larger list, all other images in that list
% will be simply 'lost', not destroyed.
%
% Also if the crop generates a list of images only the first image is resized.
% And finally if the crop succeeds and the resize failed, you will get a
% cropped image, as well as a 'false' or 'failed' report.
%
% This function and should probably be deprecated in favor of direct calls
% to CropImageToTiles() or ResizeImage(), as appropriate.
%
% The format of the TransformImage method is:
%
% MagickBooleanType TransformImage(Image **image,const char *crop_geometry,
% const char *image_geometry,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image The transformed image is returned as this parameter.
%
% o crop_geometry: A crop geometry string. This geometry defines a
% subregion of the image to crop.
%
% o image_geometry: An image geometry string. This geometry defines the
% final size of the image.

Purpose:
MAIN is the main program for MD.
Discussion:
MD implements a simple molecular dynamics simulation.
The velocity Verlet time integration scheme is used.
The particles interact with a central pair potential.
This program is based on a FORTRAN90 program by Bill Magro.
Usage:
md nd np step_num dt
where:
* nd is the spatial dimension (2 or 3);
* np is the number of particles (500, for instance);
* step_num is the number of time steps (500, for instance).
* dt is the time step (0.1 for instance)

void compute(int np,int nd,double pos[],double vel[],double mass,double f[],double *pot,double *kin)
/******************************************************************************/
/*
Purpose:
COMPUTE computes the forces and energies.
Discussion:
The computation of forces and energies is fully parallel.
The potential function V(X) is a harmonic well which smoothly
saturates to a maximum value at PI/2:
v(x) = ( sin ( min ( x, PI/2 ) ) )^2
The derivative of the potential is:
dv(x) = 2.0 * sin ( min ( x, PI/2 ) ) * cos ( min ( x, PI/2 ) )
= sin ( 2.0 * min ( x, PI/2 ) )
