[mvapich-discuss] Problem at OSC with mvapich debugging

[Tim Hartley]

Hi,

I'm trying to debug my application with gdb, but am having trouble
getting the debugger to start with OSC's installed mvapich.

I'm using the module mvapich-1.1-gnu on OSC's glenn cluster.

Here are the installation details:
$ mpicxx -v

Here is the error message:
$ mpirun_rsh -debug -np 1 -hostfile /tmp/DCMPI_IPOl0k /home/osu4771/app
debug enabled !
RSH/SSH command failed!: No such file or directory

Child exited abnormally!
Killing remote processes...ModuleCmd_Load.c(200):ERROR:105: Unable to
locate a modulefile for 'cuda'
DONE

This is with an extremely simple application.

Do I need to spin my own mvapich install, or ask for the OSC guys to
rebuild that module?

Thanks,
Tim
