A couple weeks ago we asked for some guidance from COMSOL on a computer upgrade - for running big problems - 10 to 20M DOFs.
We were directed to this page
www.comsol.com/support/knowledgebase/866/
where we are told that speed is primarily dependent on the product of the number of sockets and the number of memory channels per processor.
We followed that advice (also from several other COMSOL sources) and spent $23K on a computer upgrade that is about 30% slower than the cheap computer we'd been using for about two years. (But of course, we first had to bring our subscription up to date to transfer our license to the new computer.)
Our previous computer was a single socket, i7-3930K, (6 cores, 3.2 GHz) 64GB RAM.
The new computer is a 4-socket E5-4627 v2 (32 cores, 3.3 GHz) with 512GB RAM.
Does anyone at COMSOL care how much their customers waste on computers because of bad advice?
Is anyone at COMSOL concerned about helping customers who need to run really big problems improve the performance of COMSOL on high-end computers?
