Subject: Re: Splitting mask keyspace

Okay I wanted to post some update about progress I have made with my
small distributed setup. Firstly on  avx2 nodes with only physical
cores I switched to using for and results while on avx and avx2 nodes
with virtual cores (and as a result need higher fork number to reach
full power) I sticked with openmp. This allowed to for example use
node numbers much lower than actual fork number required and I was
able (for john nodes) to completely switch to --node to evenly
distribute tasks. As a result of those changes average system speed
increased by around 50%.This is just rough estimate as often faster
nodes (due to not proportional task division) had "wait" for slower
nodes to finish their part of job. Now all nodes finish in similar
eta. There are still some differences that could be addressed but I
think those were caused by openmp being not "proportional" in
comparison to fork based nodes. However now that Solar Designer fixed
this issue here: I
will try completely switching to fork and rewrite current logic so
possible nodes will be even more "in sync" :)
