Having trouble getting transform-hostname working

[Bradley W Settlemyer]

Hello

   Mpiexec seems to be exactly what I need for launching my jobs. 
However, I am having trouble using the transform-hostname option.

   Here is my mpiexec call:

/opt/mpiexec/bin/mpiexec --comm=pmi --transform-hostname=s/./gige/ 
/opt/mpich2/examples/cpi

This should pretty easily create invalid hostnames, however, I get the 
following in my output:

Process 0 of 8 is on a13.parl.clemson.edu
Process 1 of 8 is on a13.parl.clemson.edu
Process 2 of 8 is on a12.parl.clemson.edu
Process 4 of 8 is on a11.parl.clemson.edu
Process 6 of 8 is on a9.parl.clemson.edu
Process 3 of 8 is on a12.parl.clemson.edu
Process 5 of 8 is on a11.parl.clemson.edu
Process 7 of 8 is on a9.parl.clemson.edu
pi is approximately 3.1415926544231247, Error is 0.0000000008333316
wall clock time = 0.005041


I tried adding a little debug output in the forked child for running sed 
in the get_hosts.c file, but did not receive any output.  Is this 
feature supported and working?  Other than that, mpiexec seems to 
integrate easily with the latest version of torque and maui.

Cheers,
Brad
