[Pw_forum] segmentation fault

[庞瑞(PANG Rui)]

Ah, it is intersting. I also got a similar problem but with PWCOND. And I found the code stoped at a line of sum, quite unblievable. But my PW.X works well. I think it is not a memory problem.

Subject:  [Pw_forum] segmentation fault

 
I've been running an SCF calculation for a fee Ni system on High performance cluster. The job runs fine with processors 7 or less but it always leads to segmentation fault if the no of processors exceeds 7.
The job takes 4-5 days for the run. 
Is there any way to increase the no of processors so that it doesn't lead to the error ?
mpirun noticed that process rank 0 with PID 6353 on node c7c exited on signal 11 (Segmentation fault).
or excessive memory leakage.
