Dear Yambo developers
I have to perform a calculation at gamma point, and I would like to know which is the best
parallelization strategy in this case.
More processors on "eh" or more processors on "t"? Or a balanced distribution between the two.
And how many processors can I use in such a way to be efficient?
Is openMP convenient?

Re: Better parallelization strategy for BSE at Gamma Point
DearJavad,
you can combine both strategies, "eh" first and then " t", have a look here for a discussion about the number of cpu you can use and the efficiency of the parallelization.
OpenMP is present, but it still need a deep testing. You can have a try but at this stage, I think it is not convenient.
Best,
Daniele
