[mpich-discuss] Questions about binding process to core.

[Fernando Luz]

Hi,

I tried to run a parallel program with 33 tasks using the binding
parameter how as specified in hydra manager
(http://wiki.mcs.anl.gov/mpich2/index.php/Using_the_Hydra_Process_Manager#Process-core_Binding), but I didn't have success.

I received this error message.
---------------------------------------------------------
[mpiexec at masternode1] HYDU_process_mfile_token
(./utils/args/args.c:262): duplicate local binding setting
[mpiexec at masternode1] HYDU_parse_hostfile (./utils/args/args.c:327):

Some infos about my execution:

mpiexec -verbose -n 33 -f hostfile.txt ./cpu_mpelog3 input.txt

My host file is:
