hi rich, there is lots to be gained by running multiple jobs simultaneously on a cluster; mesa (or any other non-mpi code) in embarrassingly parallel mode. for example, a parameter survey involving a 100 stars. fxt On Jan 5, 2012, at 2:41 AM, Richard Townsend wrote: > I'm not even sure what is to be gained from running MESA on a supercomputer. 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.
