Re^2: How should one use Firefly with IntelMPI?


Ok, thanks for reply.
However, I still can't understand how to make it work.

Here is my script to run firefly:


export PATH=/media/olgerdovich/ssd/QuaChem/firefly820_linux_intel/:$PATH
export LD_LIBRARY_PATH=/opt/intel/impi/

firefly820 -i /media/olgerdovich/ssd/QuaChem/firefly_files/inps/bench13.inp -o /media/olgerdovich/ssd/QuaChem/firefly_files/outs/bench13.out  -t /media/olgerdovich/ssd/QuaChem/firefly_files/temp /media/olgerdovich/ssd/QuaChem/firefly_files/temp.1 /media/olgerdovich/ssd/QuaChem/firefly_files/temp.2 /media/olgerdovich/ssd/QuaChem/firefly_files/temp.3 -stdext -r -p -f -np 4 &

and it run Firefly only in serial mode, just ignoring string "-stdext -r -p -f -np 4 "; if I put this string before "-t ..." key, it returns


   Unable to create/chdir to a temporary working directory

Obviously, there is some silly mistake in my way to run firefly, but I can't catch the problem.
Please, help me make it work.

Thanks in advance

UPDATE: SOLVED, solution in the parent post. Indeed, it was a silly mistake.
