Hi

the problem is related to the size of your calculation.
With the cutoff asked and a box of size 150 Angstrom you
request about 3.5 10^9 plane waves. 
CP2K can probably handle such large systems, as long as the 
number of plane waves per MPI process is smaller than 
2^31 (4 byte integer). I never tested such a case.

Looking at your system, I would suggest to use a (much) smaller box
or if you really want to do this, go to a very large computer
with many processor and a lot of memory.

regards

Juerg

I'm new to this program and trying to do an calculaiton with my system
I made an input but there's so many errors.
I corrected my mistakes step by step.
But I meet a problem which I can't figure it out what the problem is.
I attached my input and output.
