Ciao Alejandro
just run a parallel calculation (optics or GW) and put -M in your script
you will see something like:
<---> [Distribute] Average allocated memory is [o/o]: 35.00000
that is telling you how much the memory usage was reduced

What does "35.00000" mean in the above line?
In my calculation, the l-* file reads the following:
<01s> [Distribute] Average allocated memory is [o/o]: 9.023438
Does "9.023438" mean 9.023438 GB per CORE? But, our cluster has only 4GB memory per core.
Regards.

Dear Hyungjun,
that number is a percentage.
So the relative reduction with respect a calculation without memory distribution.
Hope it is clear,
Daniele

Dear Daniele Varsano:
Thank you very much for your quick reply.
I am very sorry. I was too stupid to realize that "o/o" means "%".
I am always grateful to you for your great effort for maintaing the code and this forum.
Regards.
