[mpich-discuss] SMPD, Problem launching when using -host

[James S Perrin]

Hi,
     Processes fail to start if -host is used for only some but not all 
processes when launching. ie the machines that some processes launch on 
is left up to the smpd to allocate.

eg

mpiexec -n 1 -host roobarb master : -n 1 slave

when -localroot is used the following fails unless -host is also 
specified for the master.

mpiexc -localroot -n 1 roobarb master : -host roobarb -n 1 slave

Using MPICH2 1.0.7 on WinXP ia32.

Regards
James
