Dear developers and users,
In order to check if DFTB+ can be used to evaluate the system sizes
relevant for my study within the available computational resources, I tried
to do a bulk simulation for Si. Initially I started with 64 atoms, which
went perfectly well. However when I increased my system size to 1728 atoms,
I received the following error message
In file
'/mnt/scratch/aradi/gnu-mkl/dftb+/src/dftbp/dftbplus/initprogram.f90',
around line 4665: Error allocating 294107480064 bytes: Cannot allocate
memory
Does this happen because I am working with the executable without compiling
DFTB+ on my system. Also, I have only 32GB of memory in my system.
Thank you
