[mpich-discuss] Is there a way to set timeout to mpi process launch?

[Halim Amer]

There is no way to do that in Hydra. The only way is for the user to set 
timers in the application and MPI_Abort if MPI_Init is taking too long. 
It is up to the user to determine what "taking too long" would mean.
