Hello everyone,
I compiled CP2K-3.0 on CRAY-XC40 for cuda using arch file: 
CRAY-XC30-gfortran-cuda.psmp. I ran test input file for water and it was 
successfully over. But when I am running jobs for my actual system, I am 
getting the following error:

CUDA Error: out of memory

           17 dbcsr_data_new
           16 make_images
 
I tried using CUDA SUBSECTION (for memory keyword) also in GLOBAL section, 
but it didn't work. Attached is the output file.
Can anyone please help, what might be wrong? I would also like to know how 
can I make sure that my job is using GPU card.

Thank you,

Aman Jindal
