Hi,

As you have a loop, there should be 30 repetitions. If your MPI is misconfigured, you can actually end up with two independent Espresso instances, printing 30x number of cores. Add a "puts [setmd n_nodes]" to the script to see how many cores Espresso is working on.

Best,
Axel

Dear Espresso users,

I have this loop in my script:

set bj 0.1
for {set b 1} {$b<30} {incr b} {
set bj [expr $bj+0.1]
puts "$bj"
puts [inter coulomb $bj p3m tune accuracy $accuracy]
integrate 100
}

when I want to run my script parallel, the steps of the above loop are recalculated over and over again!
Could anyone help me solve it?

Best,
Roya
