[mpich-discuss] HYDRA and kill process

[Torquil Macdonald Sørensen]

Hi!

With mpich-1.3.2, say I run a parallel job consisting of two processes running a 
hostA and hostB. They are started by running mpiexec on hostA.

If I (on hostA) hit CTRL-c to kill my job, the process on hostB keeps running...

With earlier MPICH2 versions, without HYDRA, the behaviour was different. The 
whole job (all processes on all hosts) were killed when I hist CTRL-c on the 
host where mpiexec was run.

Any pointers on how to "restore" the old behaviour when using the newest MPICH2 
and HYDRA?

Or is it a bug?

Best regards
