Re: OPR Programming Challenge


OK guys.

I just wrote, compiled, and ran a 32-bit single-core native app on an 8-year-old Pentium D machine running 32-bit XP Pro SP3, and timed it using RDTSC instructions embedded in the code.

It took 11.9 milliseconds to read the raw data file (cached in RAM) and generate the alliance score vectors and the sparse design matrix.

Using 16-bit unsigned integers for the team numbers and scores, generating the sparse matrix directly from the raw data, and compiling to native code saves a lot of runtime.
