 Author: identaton [ Thu Aug 09, 2018 5:37 pm ] Post subject: BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES Hello! I am testing the calculations by EPW. The problems is like below, when doing the procedure "Solve anisotropic Eliashberg equations on imaginary-axis", it output like "BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES". I also try changing the etf_mem from 0 to 2, it does not work. Can anyone give me any suggestions? Thanks a lot._________intel18+mkl18+impi, etf_mem=0 give the following output: temp( 1) = 0.0005 K Solve anisotropic Eliashberg equations on imaginary-axis Total number of frequency points nsiw ( 1 ) = ****** Cutoff frequency wscut = 1.0000 ==================================================================================== BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES= PID 13981 RUNNING AT compute1511= EXIT CODE: 9= CLEANING UP REMAINING PROCESSES= YOU CAN IGNORE THE BELOW CLEANUP MESSAGES===================================================================================_____when using intel12+mkl12+openmpi, the output is: temp( 1) = 0.0005 K Solve anisotropic Eliashberg equations on imaginary-axis Total number of frequency points nsiw ( 1 ) = ****** Cutoff frequency wscut = 1.0000 4 total processes killed (some possibly by mpirun during cleanup)__________by playing with some input parameters, I now get the following message from the output: Total number of frequency points nsiw ( 1 ) = 184691 Cutoff frequency wscut = 1.0000 Size of required memory per pool : ~= 5.7537 Gb AKeri is calculated on the fly since its size exceedes max_memlt The pbs jobs are still there, but the calulations was stuck without updating; I also tried to give max_memlt with bigger values (>5.8 Gb), but the calculations then give "= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES" again. I will appreciate it very much if someone can help me fix the problem.

WRITE(stdout,'(5x,a,i6,a,i6)') 'Total number of frequency points nsiw ( ', itemp, ' ) = ', nsiw(itemp)The equations should be solved in the vicinity of 0 K, but I wouldn't go below 1 K. You may also want to reduce wscut. What is the estimated critical temperature with McMillan formula in your case?Best, Roxana

In my case, the Tc is very very low (e.g. using mu=0.05, the Tc is ~0.001 K). I know my system is not physically meaningful, I just want to test if the code can fit my systems for calculations. Now I guess I know where does the problem come from, following you comments above. Thanks a lot.
