Hi, We have a cluster with InfiniBand network that works flawlessly. The problem is that the binary IB drivers are proprietary, and the company has been recently absorbed by a larger one, which means that the driver support for Mellanox cards is now frozen. The proprietary drivers prevents to upgrade or tweak the kernel, or to use a recent version of mpich2 (with MPI 2 and one-sided communications). Fortunately OpenIB (openib.org) has published open source drivers which are included in the latest kernels >= 2.6.14. Before exploring this option I just want to ask the list if anyone has used the OpenIB drivers for production work, in particular with an open source MPI? Thanks, Dan
