Hi!
I'm using OpenMPI 1.3 on ten nodes connected with Gigabit Ethernet on Redhat
Linux x86_64.
I run a test like this: just killed the orted process and the job hung for a
long time (hang for 2~3 hours then I killed the job).
I have the follow questions:
when network failed or host failed or orted deamon was killed by accident,
How long would the running mpi job notice and exit?
Does OpenMPI support a heartbeat mechanism or how could I fast detect the
failture to avoid the mpi job hang？
thanks a lot!
