Thanks John. I can reproduce this error. I've created a ticket for this issue. http://trac.mpich.org/projects/mpich/ticket/1773 -- Pavan On 11/08/2012 02:13 PM US Central Time, John Fettig wrote:
When I run
mpiexec -configfile myConfigFile
the input taken from the lines of myConfigFile is truncated at 1024 characters. If the executable doesn't appear in the first 1024 characters, mpiexec will complain that you didn't specify an executable. I see this because I set -env LD_LIBRARY_PATH which in my case is quite large.
Here is the output of mpiexec -info
