Intel C++ compiler 2017 MPI 64-bit C++ support

Hey,

Is there any way to get 64-bit support for the Intel MPI libraries in 2017 for C++ applications. It used to be part of the 2016 package and it was removed. I need some of the newer features of many of the other packages provided by Cluster XE but the MPI in my opinion has gone through a downgrade.

Thanks,

Will

It was 32bit mpi support which was removed in 2017. Among things to check if on Windows would be whether global environment variables from previous installations are cleaned up.

I feel the need to point out that the release notes for 17.0 patch 2 state 

- (SDK only) Support for Intel(R) 64 architecture and Intel(R) MIC Architecture clusters using:

 Intel(R) C++ Compiler for Linux* OS version 14.0 through 16.0

 Intel(R) Fortran Compiler for Linux* OS version 14.0 through 16.0

 GNU* C, C++ and Fortran 95 compilers

This to me implies that there is not support for 64-bit MPI calls in C++ applications.

https://software.intel.com/sites/default/files/managed/8c/b0/intelmpi-2017-update2-release-notes-lin...

And additionally the developer's reference also states for both linux and windows:

There is currently no support for C and C++ applications. 

This can be found in the section Miscellaneous>ILP64 Support
