Re: [OMPI devel] carto vs. hwloc

2009-12-14 Thread Jeff Squyres
I had a nice chat with Ralph this afternoon about this topic. He pointed out a few things to me: - I had forgotten (ahem) that carto has weights associated with each of its edges (and that's kind of a defining feature). hwloc, at present, does not. So perhaps hwloc would not initially replace

[OMPI devel] carto vs. hwloc

2009-12-14 Thread Jeff Squyres
Question for everyone (possibly a topic for tomorrow's call...): hwloc is evolving into a fairly nice package. It's not ready for inclusion into Open MPI yet, but it's getting there. I predict it will come in somewhere early in the 1.5 series (potentially not 1.5.0, though). hwloc will provid

I don't really want to throw fud on this list but we've seen all sorts of oddities with OMPI 1.3.4 being built with Intel's 11.1 compiler versus their 11.0 or other compilers (gcc, Sun Studio, pgi, and pathscale). I have not tested your specific failing case but considering your issue doesn't

Hi Ralph, I took the Dec 10th snapshot, but got exactly the same behavior as with version 1.3.4. I just noticed that even this rankfile doesn't work, with a single process: rank 0=node01 slot=0-3 [node01:31105] mca:base:select:(paffinity) Querying component [linux] [node01:31105]
