Hi all,

i need to get the rank number for each process through an environment variable. after some googling i found MPD_JRANK here

http://developers.sun.com/sunstudio/documentation/techart/mpi_apps/

but the variable seems not to be working withmy 4.0.1.007 MPI install...

I am looking for something similar to Open MPI's OMPI_COMM_WORLD_RANK.

thanks a lot!
Mihai

After some examination of the intel MPI env var set, I found $PMI_RANK that did the trick.
