[scyld-users] slave processes hang

[Pirabhu Raman]

I am trying to use totalview to debug MPI processes. While it works fine
on rank 0, all the processes hang on pthread_create call on other ranks
when started with totalview for debugging. The same program runs fine
without totalview. I am using the basic/demo version of Scyld operating
system. I was wondering whether debugging works at all in Scyld systems.
If so, could anyone provide any suggestions or pointers to resolve this
issue.

Thanks in advance,
Pirabhu
