Hello there,
I've been struggling for quite a bit now to try and use the debugging tool 'idb' in parallel mode. I would like to use it to debug my Fortran 90 program compiled with ifort (single process) and with mpif90 (multi-processes).
I succesfully managed to debug a single-threaded program. In order to run idb in parallel mode I followed the instructions in the manual (
http://scv.bu.edu/computation/linuxcluster/docs/intel_comp_docs_7.1/docs/idb_debugger_manual.htm#at.para
, at "Starting a Parallel Debugging Session"
) but this is what I get when I launch my program caled "
les3d-mp" :
[up0002.hpcvl.org:07605] procdir:
/tmp/openmpi-sessions-hpc2133@up0002.hpcvl.org_0/37008/0/0

I would really appreciate your help,
