odd "quiet death" when running GW on 5.0.4

Dear all,

I am facing a weird issue; I have run a calculation for G0W0 on this system (same cell, positions, pseudos, cutoffs etc) with yambo 4.3.2 without any issue, but with the new version of yambo it crashes without any error every time at the following step:

Code: Select all

 [06] Local Exchange-Correlation + Non-Local Fock
 ================================================

 [VXC] Plane waves :   7075
 [EXS] Plane waves :   61093
  
 QP @ state[ 1 ] K range:  1  1
 QP @ state[ 1 ] b range:   45   55
  
 [FFT-HF/Rho] Mesh size:   93   93   69

the log in this case will say

Code: Select all

there is no other error, the RAM consumption is rather marginal (~10% of the available RAM) - any ideas?

compiled using intel-19.

Thanks in advance for any help :)

Dear Christoph,
actually not easy to spot the problem.
Any error message from the log files of the other CPUs?

If not, can you try to recompile the code using internal linear algebra (--enable-int-linalg in the configure) and see if this solve the problem?

Best,
Daniele
