Those are traditionally used for exclusion between the threads of a single process. In our situation we needed locking between processes. One way to lock acrossprocesses is to use a form of sharedmemory, but that's not very portable unix/windows. Given the very low performance requirements of our locking, a filesystem solution is fine.

For anybody trying out the new P1, please don't forget to start with a few knownfactors and verify they are detected correctly. If any factor should be found and isn't please report as it's a very serious bug.

During P2 (second stage), it is possible to run GCD as often as desired. Right now a GCD is started every 5minutes after the completion of the previous GCD. This is likely overkill (too often) and I plan to change the interval to 10m or 15m. But that's the explanations for the middle GCD you see. One more GCD at the end of P2.

You really need to tag MS API links as NSFW, I gagged ;)
You're right, it looks like it's trivial to have completely separate (as in no child/fork) processes share a posix named semaphore so that should work just as well: https://github.com/yvoinov/interproc...er/named_sem.h

Or add a use option GCDinterval n where n is minutes between P2 GCDs, or n% of B2 or something that scales well. There is seemingly a way to change B1; drop the number of tests saved from 1 or 2 to zero, and a continuation shows B1=0. Gpuowlwin v7.018 worked to duplicate a factor found recently with prime95. https://www.mersenne.ca/exponent/100342469 But there was an issue with v7.0 renaming worktodo.txttmp to worktodo.txt afterward, that caused the run to terminate. If the iteration times look a bit long, it's because there was an instance of v6.11380 running LLDC of 178476583 on the same 8GB RX480 also. rx480, Windows 7 Pro x64 v6.11380 alone, 178M LL: 6733us/it = 148.52 it/sec V7.018 alone, 100M PRP&P1: 4358us/it = 229.46 it/sec Combined: V7.0 9528 us/it 104.95 it/sec 45.74% of single throughput V6.11 12232 us/it 81.75 it/sec 55.04% of single 100.78% Code:
