Re: FFT Parallelization not working with 6.6.3 + ifort

Based on Yann's suggestions, I performed the same tests but with twice the memory allocated.To do this, I halved the cpu-per-node ratio to double the memory available to each processor. These runs were allocated over twice the estimated memory requirement given by abinit! (how innacurate are those e...

I have large jobs (supercell calculations) that I need to run with limited memory, so I'm thinking I ne...

I have had no problem getting it to parallelize over k-points, but activating npband seems to be a poison pill. I am trying to do defect supercell calculations for MgS...
