[QE-users] [SUSPECT ATTACHMENT REMOVED] Cuda error on marconi100

[Pietro Bonfa]

Dear Mina,

the problems that you describe have different origins.

The first one is clearly related to the GPU implementation, and I kindly
ask you, if possible, to share QE's input and output files within an
issue on gitlab (here https://gitlab.com/QEF/q-e-gpu/-/issues ) to
investigate further.

The second problem is instead related to I/O and it's hard to understand
if the issue is related to the code or to a failure of the parallel
filesystem. By the way, I've experienced random problems with I/O on
Marconi100 as well.

Best regards,
Pietro
