Re: OPR Programming Challenge

I've been a bit busy, but since the light is at the end of the tunnel, I met with Jim, a mathematician on our team to see if he would do this with our sparse matrix tools. The first screenshot shows the breakdown of times. The second is the code written in LV.

He is going to tinker to see if he can find a better way to build the sparse matrix, since most of the time is spent before invoking the solver.

This was timed on a Windows VM that has 4 cores running on my macbook 2.7GHz core i7. Jim was running on a desktop machine which I don't have details for, and he wasn't writing the file. His was somewhat faster. My cores are only about 70% utilized since most of the time isn't spent in the solver.
