Failing at address Segmentation Fault

[Shubhang Goswami]

Hi,

I have been using Ipi with LAMMPS with no problems on the cluster in my university. 

Although I installed ipi and LAMMPS and wanted to run some ipi on a new cluster and it has been giving me segfaults.

I have been recieving Signal seg fault errors, the following is the full error

I do not know what to do or how to resolve this error and am not sure if this is a problem of the cluster or of ipi.

Sincerely,

Hi Shubang, thanks for reporting - we need more information to check where this problem lies.

Could you open share inputs, outputs and submission scripts? This can be done here or as an issue in the i-PI repository https://github.com/i-pi/i-pi/issues (probably better there).
