General Notes

130.socorro (base): "nullify_ptrs" src.alt was used.

MPI startup command:
  aprun command was used to start MPI jobs. A flag below
  is used to place processes onto 16 cores out of 32 on a node:
  -cc 0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30

export MPICH_NO_BUFFER_ALIAS_CHECK=true
  If set, the buffer alias error check for collectives is
  disabled. The MPI standard does not allow aliasing of type
  OUT or INOUT parameters on the same collective function
  call. The default is false.

Network:
  3D Torus

Job placement:
  PBS is used for job placement.
  Compute nodes are selected by PBS.
  No specific node selection is used.
