Please let's coordinate a search effort. I would like to join to help out with preference under win 64. If not possible I would need some direction on how to start and run the client under linux. If a build with 4 instances can be shared in a zipped file, where I would only need to unpack and run it, would be great.

This is the easy part, and the code do everything, if needed then update the start point etc. as you have seen. The hard part was to guess the memory usage for different type of clusters, some of them had peak in the 2nd stage (the goal was the 1st stage). But it was possible to find 'const' value for that it was at most const*interval*log(en). We used all memory on each cluster. And all cores, but it isn't needed for the code, and it is also possible to use different number of cores after a restart (that's the reason why I don't save the number of used cores). We have seen at some clusters that there was a memory jump after a completed 'interval' of primes (examined this, but still don't know why it happens). So on each run we had to test only 1 block of interval to avoid this, so in [st,en] there were at most interval primes for given 'e'.

And every kind of 'e' value has run on the slower machines. Obviously we could use only the fastest computers with 256GB Ram to minmize the cpu clock time but it would require much more wall clock time.

I am assuming that you go through the huge amount of peak memory pretty quickly. Otherwise I might be possible to write some of it to disk(especially on a ssd).
