is it possible to use Intel MPI with InfiniPath or ConnectX adapters? I guess that "no" is the answer to the former but would expect that the latter should be supported. if it's "yes" then how? thanks!

Qlogic web site shows their (old?) infinipath product supported with their own MPI: http://www.qlogic.com/SiteCollectionDocuments/Education%20and%20Resource/whitepapers/whitepaper1/HSG-WP07005.pdf

I saw the Mellanox pitch on 40GB/s adaptor yesterday. see:www.intel.com/go/cluster

It's donevia OFED support, but of course our emphasis is on pre-configured systems.

The Intel MPI library uses an standard abtract layer called DAPL to allow interoperability with a wide range of communication fabrics.

In your case, the hardware usually requires that a specific OFED version is installed to provide low level support. It will also include the definition of the available DAPL devices in your system inside the /etc/dat.conf file during its setup. DAPL devices are then selected using a proper Intel MPI Device specification.

I strongly suggest the following link, it will provide you more details.

Hope it helps,
