can someone help with log file update problem?

[Lim changmin]

Hello, I am trying to optimize some amorphous structures, but the log file would not update.
I am not sure what caused this issue.
I am attaching the log file

the log file won't update and so as hdf5 file

It just stopped at this point

thank you

Can you share what kind of CPU, Operating System and network interface (ethernet/infiniband) these nodes have?

On another note: This level of parallelism is way overkill for this system and will probably make it run slower, not faster. You're trying to use 18 processes so find the eigenvalues of a 1004x1004 matrix, which is honestly not that big and can be done pretty quick on even a laptop CPU.

I suggest that you run on a single 48 core node with 16 MPI processes and 3 OpenMP threads. This will ensure that each MPI process get one k-point and three CPU cores are working on the matrices for that k-point.
