Hi, according to manual, pw.x scf R&G parallelization should scale well in respect with memory requirement (i.e., total memory required should not increase much with the number of threads and should decrease per CPU almost linearly ) However, what i have noticed, the amount of memory used per CPU does not decrease more than 2 times. For example, running on 8-node SMP machine with 8 threads consume 4 times more memory comparing with one only thread ( with 1 pool, procs/pool=8 )
Is this expected behavior? Can somebody clarify this? Best Regards, Alexander Shaposhnikov
