In Tutorial on Many-Body calculations in parallel, for calculating the screening by using Hilbert transform method, it is said that the size of the matrix of sf_chi0q0 will decrease when increasing the number of processors by setting gwpara=2. Is this true? I mean I did change the number of processors, but the matrix size is always the same, which is 3.8GB. Then the code stop and print out a "out-of-memory" error. Following is my input, any idea about that?
