You should be able to get a core dump pretty easily by doing
something like this:
{ char *foo = 0; *foo = 13; }
Ensure that your coredumpsize limit is set to "unlimited" in the
shell on all nodes where you are running your MPI processes. It's
also helpful to set Linux (I'm assuming yo
I'm using OpenMPI, and the documentation says that only a totalview
style of debugger can be used. With that in mind, all I want to do is
get a core-dump when a process crashes. I can then just load the core
into GDB. Is there any easy way to do this?
I tried calling signal(SIGSEGV, SIG_DFL); sig
