Subject: [OMPI devel] [PATCH] Improving heterogeneous IB clusters support.
From: Vasily Filipov (vasily_at_[hidden])
Date: 2009-09-23 05:05:38


Hello,

Some time ago Mellanox proposed design that should improve current
support for heterogeneous clusters (see Design.txt).The design was
accepted by IB vendors, and now we propose patch that adds a
heterogeneous cluster support. The path leaves one issue that we do not
resolve completely. If 2 different procs have different QPs
configuration (P/S/X) we print nice warning message that describes that
such configuration is not supported and it propose way to resolve the
issue. Theoretically it will be best to provide solution that
automatically will resolve the problem, but it will require significant
changes on openib blt that we don’t want to introduce in this stage.

Please comment.

Regards,
Vasily
