Hi all,
I'm in the process of downloading PGI CDK 7.0.
Does it support Mellanox IB? (I'm currently using OFED 1.2)

thank you

Hi Brady,

We include MPICH and MPICH-2 with the CDK. Both of which use basic TCP/IP and are not optimized for Inifiband. You'll need to obtain either OpenMPI or MVAPICH and build the MPI libraries using the PGI compilers.

The only issue that you might encounter is that the PGI debugger, PGDBG, is configured for use with MPICH. Hence, if you need to debug your application, you'll need to use MPICH.

Hello all,
I did see PGI was testing CDK with IB in another post.
any plans to support IB in your CDK product?



thanks

Hi Brady,

My understanding is that we're in the process of adding debugger support for a MPI implementation for inifiband. However, I don't know the time frame. Once debugger support is available, we'll then be able to offer a pre-compiled MPI inifiband library with the CDK.
