[OMPI devel] ORTE tutorial
This is intended for those European folks that plan to participate in the ORTE tutorial on Sept 28-29. I am sensitive to the fact that you are well ahead of us in terms of time. Is there some way we could organize our agenda to make things easier on you? If you review the syllabus posted on the OpenRTE web site (www.open-rte.org, look at the news column on the right side), are there particular topics you definitely want to attend, and others you would rather not attend? You will note that I already have the materials for some of the modules posted on the site. I will be adding more modules in the next few days to complete the materials. This may give you a better idea of what I intend to cover, and to what depth. My intent is that this will be an interactive tutorial, with design discussions and changes being made as we go. I need to keep the modules in some order to make then understandable, but hate to impose upon you late into your night just so you can hear a topic of interest to you. Please let me know if there is anything I can do to make this easier on you. Thanks Ralph

It won't appear in svn-/tmp/ until our local mandarin manages to finish his vacation and sign the license paper.

[OMPI devel] btl_openib_max_btls
The ompi_info command shows the following description for "btl_openib_max_btls" parameter MCA btl: parameter "btl_openib_max_btls" (current value: "-1") Maximum number of HCA ports to use (-1 = use all available, otherwise must be >= 1) Even though I specify "mpirun --mca btl_openib_max_btls 1 ." 2 openib btls are created(the HCA has 2 ports). When I try to run Open MPI across 2 nodes (one node has an HCA with 2 ports and the other has only one port). Both endpoints send the QP information over to the peer. Only one endpoint exists at the peer so it prints the following error message: [0,1,1][btl_openib_endpoint.c:706:mca_btl_openib_endpoint_recv] can't find suitable endpoint for this peer [0,1,0][btl_openib_endpoint.c:913:mca_btl_openib_endpoint_connect] error posting receive errno says Operation now in progress [0,1,0][btl_openib_endpoint.c:737:mca_btl_openib_endpoint_recv] endpoint connect error: -1 Is "btl_openib_max_btls" the maximum number of BTLs or maximum number of BTLs per port (which is what the current implementation "init_one_hca()" looks like)? -Nysal
