added 2 second delay on each startup because the stock run won't work properly on 128 cores, it only starts about 40 at a time. I figure someone can make this a command line option -delay <ms> or something.

I can confirm that this is also a problem on 64-core machines at well. The issue is that multiple instances of AFL will bind to the the same core. To see this in action: I also did some experimentation and a 100 ms delay still resulted in two threads binding to CPU #0, but a 250 ms delay seems to reliably avoid any CPU contention. |
