Intel MPI in Composer Edition ?

[JC_M_]

Hi everyone,

by using the Intel® Fortran Compiler installed on Linux with the Composer Edition version,

does we are allow to use Intel MPI for doing compilation ?

or do we need the Cluster Edition, which included the MPI Library to use MPI compilation,

thanks for your support,

best regards,

JC

The Composer Edition includes Intel MPI run-time files to support the coarray feature, but not things you need to develop MPI applications. For that you would need the Cluster Edition if you wanted to use Intel MPI.

Many thanks Steve for your reply,

but I am not sure to well understand. In fact, I am very skilled and I do not intent to develop MPI applications.

Let me be more straight:

With the Composer version, do I have the mpif90 command to compile my fortran code that I can use after using multicore process by mpiexec command ?

thanks for this clarification.

No. mpif90 is not included in the Composer Edition. As Steve wrote, you need the Intel Cluster Edition to receive the full Intel MPI library and wrappers like mpif90.

There is a table at https://software.intel.com/en-us/intel-parallel-studio-xe/details showing what is included in three Parallel Studio XE Editions available.
