[mvapich-discuss] Error 'End of file reached on hostfile'

[Pawel Dziekonski]

hi,

i'm using mvapich-0.9.9-1458 (the one that comes OFED 1.2.5.5) and it
emits error 'End of file reached on hostfile at 2 of 4 hostnames' when
machinefile contains the same hostname more than once. this happens
only for some applications, like CPMD or Amber, basic tests or HPL
work ok. machinefile is generated by PBS Pro 8 queueing system and
looks very simple, eg:

wn152
wn152
wn153
wn153

when job is enqueued with a hard requirement for 4 cpus on 4 different
nodes (nodes=4:ppn=1) than generated machinefile looks like:

wn152
wn153
wn154
wn155

and jobs run perfectly well.

is it a bug or feature? ;)
any way to avoid this?

thanks in advance, P
