Hello,

One thing to look at is the configuration of your computing cluster. If your machine has two processors per main-board these processors share the memory on that board.

If you need each processor to use all of the memory without sharing, you'll need to figure out how to submit your calculation in a way that forces the calculation to only claim one processor per main-board. There is probably a command that you can use in your queue software to specify this.

In my calculation I use 6 k-points, so I specify 6 processors but it is not enough memory for this job I am going to run calculation with 10 or 12 processors, (in my previous calculation when I specified # processors bigger than # k-points I got message that it is wasting of time because # proc not equal to # k-points).
