MPI Compilers

mpicc vs gcc¶

OpenMPI¶

# shaojiemike @ node5 in ~ [7:20:31]
$ mpicc -showme
gcc -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -I/usr/lib/x86_64-linux-gnu/openmpi/include -pthread -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi

IntelMPI¶

MPICH¶

ipcc22_0029@ln121 ~/github/IPCC2022-preliminary/run (float_trick*) [10:49:48]
> mpicc -show         
gcc -I/public1/soft/mpich/3.1.4-gcc8.1.0/include -L/public1/soft/mpich/3.1.4-gcc8.1.0/lib -Wl,-rpath -Wl,/public1/soft/mpich/3.1.4-gcc8.1.0/lib -Wl,--enable-new-dtags -lmpi

For MPICH, according to the mpicc man pages, mpicc -compile_info shows the flags for compiling a program, and mpicc -link_info shows the flags for linking a program.

-showme (Open MPI) or -show (Open MPI, MPICH and derivates) use -showme:compile and -showme:link to obtain the options automatically
