I have long been into computer chess. I have some files I wanted to protect from dodgy optical media using PAR2 files.
The old standby choked, guess 32-bit has outlived its usefulness. So I had to find a 64-bit version and I was able get a tool that was public domain so licensing was generous.
Anyway protecting 1.12TB of data, calculating Solomon Reed codes for 8192 blocks (2802 files) and 2% redundancy. MD5 can detect errors, PAR2 can fix them.
My CPU was run to the wall with 75%++ usage with all cores saturated and 75% of my RAM in use.
Execution time, more than 16 hours. Not bad at all for my R5 3600 with 32GB DDR4-3200, not bad at all. Score one for team red for brute force calculating capability.
