OpenMP programs Requirements: a compiler that supports OpenMP. Most compilers have it built in
HelloOpenMP (Book: listing 7.1-7.6) Build with either cmake or make This is a series of examples trying to correctly get our thread number Run the programs ./Hello_OpenMP and ./Hello_OpenMP_fix1 through 5
VecAdd (Book: listing 7.7 and 7.8) Build with cmake A series of examples for OpenMP threading Run the programs ./VecAdd and ./VecAdd_opt1 through 3
StreamTriad (Book: listing 7.9) Build with cmake A series of examples for OpenMP threading Run the programs ./StreamTriad and ./StreamTriad_opt1 through 2
Stencil (Book: listing 7.10) Build with cmake A series of examples for OpenMP threading Run the programs ./stencil and ./stencil_opt1 through 2
GlobalSums (Book: listing 7.11) Build with cmake Example for reduction operaions with OpenMP threading Run the program ./globalsums
Private (Book: listing 7.12) Build with cmake Example of private clause Run the program ./private Note that x and z are not defined outside the loop
FunctionLevel (Book: listing 7.13 and 7.14) Build with cmake Example of function level variable scoping with OpenMP Run ./FunctionLevel and ./FunctionLevelFort No output -- just example of variable scoping
HighLevelOpenMP_stencil (Book: listing 7.15 through 7.16) Build with cmake Examples of combining parallel regions into a high level OpenMP approach Run ./stencil_opt2 through opt6
StreamTriad (Book: listing 7.17) Examples stream_triad_opt3 and 4 Build with cmake Run ./stream_triad_opt3 and ./stream_triad_opt4
HybridOpenMP_stencil (Book: listing 7.18) Build with cmake Examples of hybrid threading and vectorization Run ./stencil_hybrid and ./stencil_threads
SplitStencil (Book: listing 7.19 and listing 7.20) Build with cmake Examples of advanced OpenMP variable scoping Run ./SplitStencil and ./SplitStencil_opt1
GlobalSums (Book: listing 7.21) See kahan_sum.c for an advanced reduction example Build with cmake Example for reduction operations with OpenMP threading Run the program ./globalsums
PrefixScan (Book: listing 7.22) Build with cmake Example for an advanced reduction with OpenMP threading Run the program ./PrefixScan
PairwiseSumByTask (Book: listing 7.23) Build with cmake Tasking example in OpenMP Run the program with ./PairwiseSumByTask
