Re: [AMBER] how many cores should be used in calculations at most

In general, the more cores the faster the calculation gets done. There is no significant decrease in efficiency by using more cores. uses serial sander for each processor and splits the number of frames as evenly as possible amongst the processors. However, if you are performing normal mode analysis be mindful of the available memory because using too many processors sharing the same memory can result in insufficient resources and the job dying.

I hope that helps.
