Re: [mesa-users] Installing MESA on a supercomputer (Richard Townsend)

Hi, Saul Rappaport and Lorne Nelson and collaborators have used Lorne's cluster to run mesa. e.g., in this recent paper http://adsabs.harvard.edu/abs/2011ApJ...732...70L they report results of 42,000 binary evolution runs with mesa -- too many even for my 12 core mac! Although I'm a coauthor I don't know the details of running on the cluster -- but perhaps Saul or Lorne can enlighten us.

Parallelism in MESA is only via OpenMP - there is no MPIA usage. As such, MESA can take advantage of shared memory architectures, but not clustered architectures. >> >> Cheers, >> >> Rich >> >> On Jan 5, 2012, at 7:31 AM, Francis Timmes <fx...@ma...> wrote: >> >>> hi ben, rich, kevin (and the mesa community), >>> >>> i had no luck compiling mesa under pgi on the nersc >>> machines hopper and franklin this past summer. the issue >>> boiled down to certain pointer structures used in mesa >>> not being supported in that version of the pgi compiler. >>> >>> i would be interested in hearing from anyone about >>> successes or failures on running mesa on any supercomputer >>> or largish parallel cluster. >>> >>> fxt >>> >>> >>> >>> >>> On Jan 4, 2012, at 3:56 PM, Ben Brown wrote: >>> >>>> Kevin, >>>> To follow up on Rich's note: you are almost certainly not going to be >>>> able to use the MESA SDK on a supercomputer.

At the moment, I have no plans to support pre-2.11 glibc versions, since 2.11 has been out for over two years. So, the only workaround would be to upgrade to 2.11 or later. >>>>> >>>>> cheers, >>>>> >>>>> Rich >>>>> >>>>> On Jan 4, 2012, at 7:23 PM, Kevin Moore wrote: >>>>> >>>>>> Hi all, >>>>>> >>>>>> I'm trying to install MESA on the Triton computing cluster at UCSD and am getting some weird errors. I know next to nothing about this so am just following the instructions on Rich's website for using the MESA SDK (which has worked fine for my macbook many times). uname -m returns "x86_64" so I'm using the 64-bit linux version of the SDK. All the setup steps seem to work fine (no errors anyway), but I run into problems during the ./install step. >>>>>> >>>>>> The first error I encounter is: >>>>>> gfortran: /lib64/libc.so.6: version `GLIBC_2.11' not found (required by gfortran) >>>>>> make: *** [const_def.o] Error 1 >>>>>> >>>>>> Perhaps tellingly, there is not a file named libc.so.6 in my mesa/utils/mesasdk/lib64. >>>>>> >>>>>> In addition, now whenever I try and use the man command I get the error: >>>>>> /usr/bin/gtbl: error while loading shared libraries: /home/kmoore-ucsb/mesa_3794/utils/mesasdk/lib64/libstdc++.so.6: ELF file OS ABI invalid >>>>>> >>>>>> Any ideas what's going on from someone who may have done this before? >>>>>> >>>>>> Thanks, >>>>>> Kevin >>>>>> >>>>>> >>>>>> >>>>>> ------------------------------------------------------------------------------ >>>>>> Ridiculously easy VDI.
