That seems to solve the problem. Would you tell me why that may happen to avoid further problems.
Thanks a lot.
Four processes doing I/O (writing and then reading) are overwhelming the performances of the disk you are using.
Using conventional SCF and just a couple of processes might work.
Anyhow, most of the times the direct option (and maximizing the number of cores used) is likely to give the fastest time to solution.
The alternative is storing the integrals in memory, if you have enough memory available.
