View Full Version : Questions concerning OpenMPI and ranks

12-09-2010, 12:37 AM

In my Open MPI appication i need to control which process is being executed on which processor.
I do this with OpenMPI's --hostfile and --rankfile options.

How can i invoke TotalView such that these options are used?

Another question: how can i set a breakpoint in a piece of code executed by several ranks
such that only one particular rank (e.g. rank #3) is stopped?
I had hoped to find this under "Conditional Breakpoints" but i didn't find a built-in expression for
the rank of a process.

Thanks in advance
