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

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.

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.
