Dear All,
I am testing Amber9 on Linux cluster. Parallel jobs are controlled by
MPICH2 (ch_p4 and ch_gm devices)
For eth0 device, I used command
mpirun.ch_p4 -np 2 -machinefile eth2
$AMBERHOME/exe/sander.MPI -O -i gbin -o md.out1 -c md12.x
The calculation was successed.
But when I switched to myrinet device with command
mpirun.ch_gm -np 2 -machinefile myri2
$AMBERHOME/exe/sander.MPI -O -i gbin -o md.out2 -c md12.x
I obtained error message as "Suspended (tty input)"
Then I tried either
mpirun.ch_gm -s -np 2 -machinefile myri2
$AMBERHOME/exe/sander.MPI -O -i gbin -o md.out2 -c md12.x
or
mpirun.ch_gm -np 2 -machinefile myri2
$AMBERHOME/exe/sander.MPI -O -i gbin -o md.out2 -c md12.x
< /dev/null
I obtained error as "Unit 6 Error on OPEN: md.out2" from both
commands.
As I know, this error message concerns overwrite output.
However, I am sure that I have added a flag "-O" (a letter O, not
zero). Any suggestion?
Best Regards,
Khatcharin
