Hmmm - the original mail I sent did not seem to show up on the list. Maybe the spam filters caught it because of the attachment. Re-sending without the attachment. If anyone wants a copy of the final slides, let me know and I can send them directly. Below is the notes from the BOF.

Stan also took a few notes and can add any additional comments if I missed anything in these notes. We had some discussion about the new RDMAoE support and if we should try to get it into OFED-1.5 or wait till a later release. Since this is such a major change and OFED-1.5 is already at RC2, several people expressed concern that it might be better to not hold up OFED-1.5 and release the RDMAoE support in a later release after it has been accepted upstream and tested more. We asked for a show of hands and more people though it was better to wait than to put the code in at this late date. This is just one data point for the EWG to take into consideration when deciding how and when to incorporate the new code. We also discussed the possibility of dropping support for RHEL 4 for OFED-1.6. Most people seemed to agree that if RHEL EL6 is out by then, that it would probably be OK to drop RHEL 4, as it would likely then not be supported anymore by Redhat. No one voiced a strong desire to continue to support EL 4 for OFED-1.6. In the WinOF section, it was announced that Microsoft has now joined the Open Fabrics alliance as a voting member. Welcome aboard Microsoft!!!! We discussed the topic of if we should continue to include the open source MPIs in the OFED releases. As was the case in Sonoma, there were people that expressed both arguments for keeping the MPIs in the release and those that thought we should not distribute the MPIs. I don't think there is a consensus either way on this one. On the topic of scalability and possible future enhancements for scalability, one person asked for verbs extensions to allow asynchronous QP create and modify calls. As for the rest of the proposed scalability enhancements, most people agreed that there are scalability issues with the RDMA CM and the SA, so work definitely needs to be done in this area. There was not too much discussion on the other suggestions that Hal had sent in, but scalability should be a major topic area for the next developer's workshop in Sonoma. There was also some discussion on the new collective offload that some of the IHVs have started to implement in hardware and that there is a need for standard verbs extensions to allow common APIs that will allow access to these offloaded collectives. Maybe this could also be a topic for the next Sonoma workshop. On the topic of building Ethernet clusters for HPC, we ran a bit short of time and so we decided to defer this topic. Maybe we can have a session on Sonoma on this one as well. Attached is the final version of the slides that were presented. woody_______________________________________________ ofw mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ofw
