Memory issue for A and B matrices #100

Closed LingoNMBU closed 1 year ago

LingoNMBU commented 1 year ago

hey,

I'm having issues with memory as the A and B matrices become large for problem 7. Initializing with a spatial resolution of 0.005 (giving matrices of 39601 x 39601)results in an out of memory error. Is the thought to subdivide the matrices into smaller parts and then compute the multiplications and solutions for subsets of the space, or is it valid to reduce the spatial resolution( matrices for resolutions down to around around 0.007 work)?

Hi @LingoNMBU!

Have you done problem 0? :) https://anderkve.github.io/FYS3150/book/projects/project5.html#problem-0

I would expect that the hint at the end of that problem would solve the potential memory challenge on most systems. If that isn't the case, you can just reduce the spatial resolution and comment on this in your report.

Thanks for the quick reply! It seems rushing through got the best of me :P
