Dear developers and users,
I'm trying to calculate the epw1.in of Pb according to the EPW manual, but an error was reported in the epw1.out file. And I couldn't find any mistake in the calculation, the files I used in the following attachments. I would appreciate it if someone could give me some suggestions on dealing with this problem.
Best wishes,
Xiangyue

Re: Error in routine elphel2_shuffle (1) when calculated epw1.in of Pb
Dear Xiangyue:
Sincerely,
H. Lee
Currently, you need to use the same number of pools as the number of cores when running EPW, that is, if you use 48 cores, you need to specify the same number of pools by adding to the run script "-nk 48" .Error in routine elphel2_shuffle (1):
only one proc per pool in shuffle mode

Sincerely,
H. Lee
Re: Error in routine elphel2_shuffle (1) when calculated epw1.in of Pb
I can run successfully according to the method you said. Thanks!
