Probably the path to your MPI include directory is wrong, the mpi* compiler wrappers will set them automatically. Translate 0 Kudos Copy link Reply Lumos Beginner 01-29-2024 04:50 AM 3,846 Views Actually, I didn't set the variable by export. My flags: ./configur...
The problem is almost certainly that you’re not using the MPI compiler wrappers. Whenever you’re compiling an MPI program, you should use the MPI wrappers: 几乎可以肯定的是,您没有使用MPI 编译器包装器。无论何时编译MPI 程序, 都应该使用MPI 包装器: C - mpicc C - mpicc C++ - mpiCC, mpi...
MPI compiler wrappers do this automatically. For example: mpicc or mpif90.If you suspect your tightly coupled MPI application is doing an excessive amount of collective communication, you can try enabling hierarchical collectives (HCOLL). To enable those features, use the following paramete...
(mpif77andmpif90) will be inoperative and will return an error on use if Fortran 77 / Fortran 90 support was not built into the MPI layer.Overviewmpiccis a convenience wrappers for the underlying C compiler. Translation of an Open MPI program requires the linkage of the Open MPI-specific ...
$MPI_EXECUTABLESpecifies the MPI executable built linking in MPI libraries. MPI compiler wrappers do this automatically. For example:mpiccormpif90. An example of running the OSU latency microbenchmark is as follows: bash ${HPCX_PATH}mpirun -np 2 --map-by ppr:2:node -x UCX_TLS=rc${HP...

Full details are in https://community.intel.com/t5/Intel-oneAPI-HPC-Toolkit/I-MPI-SUBSTITUTE-INSTALLDIR/m-p/1363427/thread-id/9210 We would like to understand why there is a need to keep I_MPI_SUBSTITUTE_INSTALLDIR in the MPI compiler wrappers instead of replacing them with the actual ...

Indeed, since the wrappers are simply thin shells on top of an underlying compiler, there are very, very few compelling reasonsnotto usempicc. When it is not possible to use the wrappers directly, the-showme:compileand-showme:linkoptions should be used to determine what flags the wrappers ...
