Re: [phenixbb] weight optimization in refinement

I'm pretty sure if you specify 8 cores to use, it will use no more than 8 cores. On 11/22/19 11:33, Alexei Gorelik wrote:

Thanks! What I meant is, phenix.refine seems to run a number of optimization threads (usually 10-14) independent of the number of cores specified (for example, 4 or 8). If i specify 8 cores, is there a way to force it to run 8 weight optimizations?

Hi Alexei,

Is there a setting to control the number of parallel weight optimization threads in phenix.refine?

nproc parameter controls number of CPUs to be used in weight optimization.

Also, is there a way to force phenix.refine to perform global real-space refinement (rsrg)?

No. There is some built-in logic, phenix.refine does it when these conditions are met and it can un-do the result if it is not an improvement.

Is there particular need to do this in your context?
