[QE-users] [QE-user] Problems when running pp.x

[Pietro Delugas]

Hi 
Impossible to tell what happened with so few details 
Could you provide  the input of the scf calculation and of pp.x at least.

Subject: [QE-users] [QE-user] Problems when running pp.x

Dear colleagues,

I ran into a problem when trying to run pp.x for my surface slab. The program stopped after a few seconds and error lines appeared, indicating two errors, namely: free() invalid memory, and munmap_chunk() invalid pointer. 

I did some research and realized that it was the problem with the C (or C++) compiler related to malloc() function and it was suggested to check the code I was running. Also, I saw elsewhere that Dr. Paolo Giannozzi once stated that it's not the problem with QE. Therefore, I have no idea how to overcome this problem.


Has anyone experienced similar cases? Can you give me some advice? All suggestions are highly appreciated.

(By the way, I am running QE on a 64-core AMD Ryzen 3999X workstation, if it helps)

Best regards,
