Replacement of intel compiler classic with intel oneapi compiler in Intel MPI
问题
我目前正在我的项目中将经典的Intel编译器替换为Intel oneAPI编译器。以前，为了能够使用Intel MPI，我使用mpiicc/mpiicpc/mpiifort调用相应的编译器，但我找不到使用oneAPI编译器的相应编译器命令（即没有mpiicx或类似的命令）。那么，使用Intel oneAPI编译器编译代码时如何使用MPI例程的当前方法是什么？

I am currently replacing the classic Intel compiler with Intel oneAPI compilers in my projects. Before, to be able to use Intel MPI, I called the corresponding compilers using mpiicc/mpiicpc/mpiifort, but I could not find a corresponding compiler command for using the oneAPI compilers (i.e. no mpiicx or similar). What is the current method to use MPI-routines when compiling code with the Intel oneAPI-compiler, then?

英文:
According to the Intel official documentation of Intel oneAPI MPI library, the current method to compile MPI routines is still with mpiicc which uses Intel Classic Compiler(mpiicpc for C++ and mpiifort for Fortran).
Take a look at the latest documentation on MPI Library https://www.intel.com/content/www/us/en/docs/mpi-library/developer-reference-linux/2021-9/compiler-commands.html. But if you want to use the Intel oneAPI/DPC++ compiler(icx), you can use this command:
-{cc,cxx,fc}=<compiler> option(<compiler> = icx/icpx/dpcpp)
Ex: mpiicc -cc=icx test.c
You can check the documentation for using LLVM compilers with Intel MPI here: https://www.intel.com/content/www/us/en/docs/mpi-library/developer-reference-linux/2021-9/compilation-command-options.html
