Oh, I see. I just got used to the output formats I used to get before I tried to introduce parallel computing. Wasn't expecting to see letters instead of numbers. Thought I might have missed some command in the code. Thank you for the clarification! Regards, Mariia On Friday, February 4, 2022

Thank you a lot for the reply, I found my mistake, it was a dull one: I removed the sparsity pattern creation line by mistake! Now it is running but the output file is unreadable, somewhat like: * AQAAAGBgLg==eNo1ioEJADAIw/L/T9MH3E+rrBWCUQI04s4cUXHvyj+Oe0F6/rRv0q8/x+QrmQ==
