Dear users,

I am getting the same error i.e " internal error 4 in TWOELECTRON4O_STORE_SCALA: 2 1" with ALGO=TDHF.
I checked with smaller k-points and even with more computing nodes.

Please let me know about the same.

Hi,

Could you please provide all relevant input and output files for your calculation according to the forum guidelines.

Dear Alexey,

Here I am attaching a tar file including all the inputs,
Please refer, INCAR.DFT as a first step of mBSE calculation i.e. scf calculation and INCAR.mBSE as the INCAR for
the mBSE calculation.
I have checked my calculation using smaller kpoints 5x5x5 also but I am getting similar error.

Please find the attachment.

If you reduce the k-points grid to 5x5x5, the BSE Hamiltonian rank according to your INCAR is 5^3*64*64=512000 and the required memory is rank^2. For double precision it is about 4TB. Are you sure that your nodes have enough memory?

You should try to reduce both the number of included states and k-points and see if your calculations finishes normally.
