Submit Notes

Scali MPI Connect's mpirun wrapper has been
used to submit the jobs. Description of switches:
  -aff manual:0x1:0x2:0x4:0x8: instruct the launcher to
     bind rank N..N+3 to the cores corresponding to the
     masks 1,2,4, and 8 respectively on each node.
  -npn 4: launch 4 processes per node.
  -rsh rsh: use rsh as method to connect to nodes.
  -mstdin none: do not connect the processes' STDIN
     to anything.
  -q: quiet mode, no output from launcher.
  -machinefile: file selecting the hosts to run on.
  -net smp,ib: prioritized list of networks used
     for communication between processes.

General Notes

Scali, Inc has executed the benchmark on Linux Networx's
Solution Center. We are grateful for the support from
Linux Networx and in particular Justin Wood in order to
finalize the submissions.
