[mpich-discuss] Bug in mpiexec -configfile

[John Fettig]

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

$ mpiexec -info
