Hello
I recently noticed this and wanted to post it here: when I using PARDISO solver with IC or OOC, I noticed that the solver consumes the same amount of memory in both cases (except I noticed that OOC version creates files on hard disk).
This really puzzles me since the impression I had was that OOC works with files on hard disk for some intermediate calculations instead of keeping all data in memory, and hence it does not require as much memory as IC version. I understand that OOC still needs to allocate some physical memory, but the observation I am seeing is that it uses almost the same amount of memory as the IC does. In one case, IC version consumes 2.5GB of RAM and I am seeing that OOC version also consumes that same amount of memory (except I see some files created on my hard disk),
I have tested this with the latest versions (11.2 Update 2 and Update 1) and got the same observation.
Is this an expected behavior? Then, what is the purpose of using OOC if it consumes the same amount of data as IC does.
Or, what am I missing here?
