Well, im not sure why should i name it /openmpi-default-hostfile Especially, because mpirun v1.2 executes without any errors. But, i made a copy named /openmpi-default-hostfile, and still, the same result.
This is the whole error message for a simple hello world program: Open RTE was unable to open the hostfile: usr/local/etc/openmpi-default-hostfile Check to make sure the path and filename are correct. -------------------------------------------------------------------------- [Mario.local:04300] [[114,0],0] ORTE_ERROR_LOG: Not found in file base/ras_base_allocate.c at line 186 [Mario.local:04300] [[114,0],0] ORTE_ERROR_LOG: Not found in file base/plm_base_launch_support.c at line 72 [Mario.local:04300] [[114,0],0] ORTE_ERROR_LOG: Not found in file plm_rsh_module.c at line 990 -------------------------------------------------------------------------- A daemon (pid unknown) died unexpectedly on signal 1 while attempting to launch so we are aborting.
