[Pw_forum] benchmark calculations for parallel PWSCF

[brsahu at physics.utexas.edu]

Dear PWSCF users,

Is it possibe to get a info on benchmark PWSCF SCF parallel  
calculations (CPU time versus number of processors) for a particular  
physical system on any computing machines (linux clusters, IBM (Power  
series), SGI, HP etc.

Is it possible to share the numbers with me if you have such numbers?  
I am aware that lot depends on what type of processors, what  
communication channel, what libraries etc. But at this stage I am not  
looking at a particular set of hardware/software set-up but only a  
rough idea of how SCF parallel run scales with
number of processors for a given system size
