Sorry. Just forgot to mention that
1. the output with adding '-ssi rpi_verbose 1' as suggested by you is as
following.
mpirun -ssi rpi_verbose 1 -np 4 bin/DG-DES-v1.0 <in_grid > output --> works
perfect { Please note that I did not use sysv}
2.mpirun -ssi rpi_verbose 1 sysv -np 4 bin/DG-DES-v1.0 <in_grid > output -->
gives following error
n0<17950> ssi:boot:base:linear_windowed: booting n0 (node18)
n0<17950> ssi:boot:base:linear_windowed: booting n1 (node17)
mpirun (locate_aschema): sysv: No such file or directory
so, the sysv is no more there. I dont think there has been change in the
system files etc and I have been able to run sysv with it without any
trouble. I am reading further about sysv but will be grateful for your quick
help.
Best regards,
ND
