The timing on this is less than ideal for me. To accommodate work on some high-voltage switching equipment, our building will be without power over the weekend. The system I use to autogen will be OFF from around 3pm today until perhaps 3pm on Monday. I will also be busy with shutting down our group's systems gracefully today and bringing them back on Monday.
The test platforms where I have reproduced the failures is NOT going to be off-line. So, I will be able to test only *tarballs* (but not patches to .m4 files) until probably Monday evening. Gilles, I think it reasonable to suspect the lib could hold a stub that returns ENOSYS for the deprecated function. I suspect that checking for ibv_create_xrc_rcv_qp+IBV_QPT_XRC should work for the rhel6.5 failure case described previously. That way the checks for the two flavors both look for a function in the lib and a constant in the header. -Paul On Fri, Jul 10, 2015 at 8:21 AM, Jeff Squyres (jsquyres) <jsquy...@cisco.com > wrote: > Yes, I seem to recall that this issue came up before... ah, here it is: > > commit 04bec4475e5a962432b73dd6254f62bb263703ab > Author: Jeff Squyres <jsquy...@cisco.com> > Date: Fri Jan 16 18:13:31 2015 -0800 > > openib: check more thoroughly for XRC > > Some systems have XRC symbols in their libibverbs libraries, but do > not have the appropriate XRC bits in their devel headers (cough cough > RHEL 6.5 libibverbs-rocee-*.x86-64.rpm cough cough). > > So expand the XRC config checks to ensure that we can actually find > one of the XRC constants that we need to compile XRC code before > ruling that we can actually build XRC support. > > > > > On Jul 10, 2015, at 10:33 AM, Gilles Gouaillardet < > gilles.gouaillar...@gmail.com> wrote: > > > > Sorry about that, and thanks for reverting the commit. > > > > Paul mentioned a patch I sent to the ml, and that worked for him. > > The commit was supposed to be a more robust version. > > For example, in rhel7, the deprecated function have been removed, but > the xrc domains is fine. > > Currently, xrc is not supported as it should. > > > > It seems rhel 6.5 has the deprecated function, but it is not in the > header files are missing it among other things. > > > > I will fix that and post a issue a pr so you can test it on rhel6.5 > before I commit it. > > > > I noticed there is no infiniband/verbs.h on a lanl test cluster (the non > cray one) > > Is it possible to have it installed ? > > > > Cheers, > > > > Gilles > > > > On Friday, July 10, 2015, Jeff Squyres (jsquyres) <jsquy...@cisco.com> > wrote: > > On Jul 10, 2015, at 2:12 AM, Paul Hargrove <phhargr...@lbl.gov> wrote: > > > > > > The only "new" (non-cosmetic) problem I observed was the failure to > detect "ConnectX XRC support". > > > It looks like Gilles and I iterated on that issue until we have > something that works now. > > > > 'fraid not. :-( > > > > Per > https://github.com/open-mpi/ompi-release/pull/384#issuecomment-120412836, > the latest commit breaks on RHEL 6.5 systems that do not have MOFED > installed. > > > > -- > > Jeff Squyres > > jsquy...@cisco.com > > For corporate legal information go to: > http://www.cisco.com/web/about/doing_business/legal/cri/ > > > > _______________________________________________ > > devel mailing list > > de...@open-mpi.org > > Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/devel > > Link to this post: > http://www.open-mpi.org/community/lists/devel/2015/07/17618.php > > _______________________________________________ > > devel mailing list > > de...@open-mpi.org > > Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/devel > > Link to this post: > http://www.open-mpi.org/community/lists/devel/2015/07/17620.php > > > -- > Jeff Squyres > jsquy...@cisco.com > For corporate legal information go to: > http://www.cisco.com/web/about/doing_business/legal/cri/ > > _______________________________________________ > devel mailing list > de...@open-mpi.org > Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/devel > Link to this post: > http://www.open-mpi.org/community/lists/devel/2015/07/17623.php > -- Paul H.
