This is nice work. These sort of fuzzers and searchers need a distributed network version to cover more space deeper and faster.
I attended his talk at DEF CON. I’m not sure if it’s in the slides, but he can do a full run in a day or less by using multiple cores and with some nice optimizations, so I don’t think we need any distributed network.
Define "full run". Brief read of paper seems the software is not designed to exhaust all possible instructions... ie: from 0x0 to 0xf.... Even if some distributed platform did, which would be good research project, it would not come close to knocking the doors of any hidden Easter Eggs as the potential trigger combinations there are much more vast. #OpenFabs, #OpenHW, #OpenSW

Over 10 years ago I tried _this_ "full" run. The smallest counterexample was prohibitively large for my resources or me screwed something :)
