How to handle this error

Concerns issues with computing quasiparticle corrections to the DFT eigenvalues - i.e., the self-energy within the GW approximation (-g n), or considering the Hartree-Fock exchange only (-x)

How to handle this error

Post by hplan » Tue Dec 28, 2010 4:38 pm

Dear Developers:

When i perform calculations of the BS matrix, i get this error

Code: Select all

[ERROR] STOP signal received while in :[05.01] Main loop
[ERROR]Mem All. failed. Element O1x require    0.52545 [Gb]
Does it mean that the PCs donot have enough memory ? But the physical memory of the PCs is 3GB per cpu core .


Thanks,

Dear Haiping,
check in the log file, the amount of memory allocated so far,
and look if you will overcame the 3Gb with the memory required
for O1x. If it is a memory problem, you cant try to reduce he FFTGvec size.

Cheers,

Daniele
