[Pw_forum] QE-GPU compilation problems

[Uri Argaman]

Dear Ivan,

Thank you very much for your answer.

It's possible that this problem is due to memory issues, but I have GPU
with 1GB and from tests that I've done a simple PW calculation of one atom
per unit cell doesn't crash with K points:
2 2 2

but does crash with K points:
3 3 3

Both calculations are preformed with ecutwfc=10.

It doesn't seems reasonable that 1GB GPU couldn't handle such a simple
calculation.

Thanks in advance,
