On my 8-year-old computer, it took ½ second to read the file and create the 2052x2052 matrix. It took 19 seconds to factor the matrix and compute OPR, CCWM, and DPR.

Hi Ether,
The numbers you have is slightly different than mine. Do you include elimination round matches?
Your 8-year-old computer must have been quite a powerful computer 8 years ago. Or is there a solver you used that is faster than the Cholesky Decomposition that I used. Here is the statistics that my son got when he was a junior in his independent study math class.
Computer Model Hewlett-Packard HP ProBook 6555b
Platform Mobile
OS Version Microsoft Windows XP Professional
CPU AMD Turion(tm) II P520 Dual-Core Processor
Memory 2807 MB
Here are the data table from tests: (time in seconds)
Size Gauss-Jordan method LU Factorization Cholesky Decomposition
100 0 0 0
300 9 1 0
500 46 8 1
750 159 27 4
1000 383 64 11
1400 1056 178 30
1800 2278 384 63
This was the 2010 data and it took 63 seconds on that slow machine.
