General Notes

 srcalt's:
   104.milc: calloc

   127.wrf2: fixcalling
   129.tera_tf: fixbuffer
   130.socorro: second_underscore

 Environment:
   export MPI_REQUEST_MAX=65536
     Determines the maximum number of nonblocking sends and
     receives that can simultaneously exist for any single MPI
     process.  MPI generates an error message if this limit
     (or the default, if not set) is exceeded.  Default:  16384
   export MPI_TYPE_MAX=32768
     Determines the maximum number of data types that can
     simultaneously exist for any single MPI process.
     MPI generates an error message if this limit (or the default,
     if not set) is exceeded.  Default:  8192
   export MPI_BUFS_PER_HOST=512
     Determines the number of shared message buffers (16 KB each)
     that MPI is to allocate for each host. These buffers are used
     to send and receive long inter-host messages.
     Default:  32 pages (1 page = 16KB)
   export MPI_NUM_QUICKS=16
     Controls the number of other ranks that a rank can receive from
     over InfiniBand using a short message fast path. This is 8 by
     default and can be any value between 0 and 32.

   ulimit -s unlimited
     Removes limits on the maximum size of the automatically-
     extended stack region of the current process and each
     process it creates.
