parallelism
Posted: Fri Feb 22, 2019 11:43 pm
Dear Daniele
I have the possibility to run my GW calculations and BSE in our cluster with 4 (node) * 16 (ntasks-per-node) in our cluster, to minimize the computation time and the problem of memory, how can I launch them using the flague contained in the input files for GW and BSE
BS_CPU = "" # [PARALLEL] CPUs for each role
BS_ROLEs = "k eh t" # [PARALLEL] CPUs roles (k, eh, t)
...........
you find the attached files for my previous calculations : GW, bse l_opt, yambo.in .....,
Note; I ran these calculations with default option " 4 node * 4 tasks" due to the memory problem which took me more than 18 days for each calculation.
Here are some details of our cluster:
