Thanks very much Brian,
Much appreciated..
mpirun -ssi rpi_verbose 1 -np 4 bin/DG-DES-v1.0 <in_grid > output --> works
perfect
However my old script
mpirun -ssi rpi sysv -np 4 bin/DG-DES-v1.0 <in_grid > output --> still
gives the same error as reported initially.
I have run all my simulations with the script above (which is now not
working). I shall change the script to as you suggested to make it work. But
I am still unable to figure out why it has been working perfect previously
for so long and now is giving this error?
Thanks again for your kind help.
Best regards,
ND
