WHPC is a software bundle representng a self-contained build and run environment for high performance sequential, multithreaded and MPI-aware numerical code on Microsoft Windows.
WHPC primary purpose is to serve as a testbed for writing and debugging numerical code to be run later in a "real" HPC environment. However, it can also be used for light computations on a local notebook/desktop as well as for education purposes.
WHPC consists of
MPI libraries and runtime
UNIX command-line utilites
Preconfigured command-line shell
The preconfigured Windows command-line shell allows to build numeric codes easily without messing up with the toolchain options, paths etc. For example, the following command-line snippet
%CC% -o runme %PETSC_DMO_CPPFLAGS% runme.c %PETSC_DMO_LDFLAGS% %PETSC_DMO_LDLIBS%
compiles a PETSc-aware C program runme.c and links it against double precision optimized MPI-aware version of the PETSc runtime which is then run locally on two processors
mpiexec -n 2 runme.exe

Happy number crunching and have fun!
