Re: [OMPI devel] OpenIB/usNIC errors

Artem, thanks for the feedback. i commited the patch to the trunk (r31922) as i indicated in the commit log, this patch is likely suboptimal and has room for improvement. Jeff commented about the usnic related issue, so i will wait for a fix from the Cisco folks. Cheers, Gilles On Sun,

Re: [OMPI devel] OpenIB/usNIC errors

This should also be fixed when we stop firing up the usnic connectivity checker when there are no usNICs present. On Jun 1, 2014, at 9:12 AM, Artem Polyakov wrote: > > 2014-06-01 14:24 GMT+07:00 Gilles Gouaillardet > : > export

That really wasn't necessary - I had tested it under PMI-1 and it was fine. Artem: did you test it, or just assume it wasn't right? On May 31, 2014, at 11:47 PM, Artem Polyakov wrote: > Thank you, Mike! > > > 2014-06-01 13:43 GMT+07:00 Mike Dubman

Ah -- I missed the attachment; I only looked at your email text. I'll have a look now... auto-failure: Ah, I found this late last week and sent a fix around internally for review. Should have something soon for trunk/v1.8. If you care: we accidentally still fire up the usnic connectivity

Re: [OMPI devel] OpenIB/usNIC errors

Hello, Jeff. Please, check attached tar ("auto-failure" dir). There I've seen the following message: -- An internal error has occurred in the Open MPI usNIC BTL. This is highly unusual and shouldn't happen. It suggests

Re: [OMPI devel] OpenIB/usNIC errors

Just to be clear: it looks like you haven't seen any errors from the usnic BTL, right? (the Cisco VIC uses the usnic BTL only -- it does not use the openib BTL) On Jun 1, 2014, at 2:57 AM, Artem Polyakov wrote: > Hello, while testing new PMI implementation I faced a

Artem, this looks like the issue initially reported by Rolf http://www.open-mpi.org/community/lists/devel/2014/05/14836.php in http://www.open-mpi.org/community/lists/devel/2014/05/14839.php i posted a patch and a workaround : export OMPI_MCA_btl_openib_use_eager_rdma=0 i do not recall i

Re: [OMPI devel] OpenIB/usNIC errors

P.S. 1. Just to make sure I tried the same program with old ompi-1.6.5 that is installed on our cluster without any problem. 2. My testing program just sends data through the ring. 2014-06-01 13:57 GMT+07:00 Artem Polyakov : > Hello, while testing new PMI implementation I

[OMPI devel] OpenIB/usNIC errors

Hello, while testing new PMI implementation I faced a problem with OpenIB and/or usNIC support. The cluster I use is build on Mellanox QDR. We don't use Cisco hardware, thus no Cisco Virtual Interface Card. To exclude possibility of new PMI code influence I used mpirun to launch the job. Slurm job

Hi, all. Ralph commited the code that was developed for this RFC (r31908). This commit will brake PMI1 support. In case of hurry - apply attached patch. Ralph will apply it once he'll be online. I have no rights for that yet. 2014-05-19 21:18 GMT+07:00 Ralph Castain : >
