Why am I getting SSE2 work units for my AVX-capable CPUs? Is't that a waste of resources?

At the beginning the server will send both apps (sse,avx), gathering statistics. After some time if there‚Äč is a clear winner you will just get that, if not you will continue to get both.
This means that there is not a big difference running sse or avx in your computer.

Yes, that is what I thought. However, the reality is, that my Core i7-4770K is getting exclusively sse2 units. Nothing else. No choice. In the recorded history of 456 units, it was sent an avx unit only once.
Well, whatever. I just thought that avx units should be faster on this CPU.

We have plenty of work to do and workunits to distribute. The work generator is slow, we may solve this problem either rewriting it or upgrading our hardware (this isn't so easy). Right now we are able to prepare around 170 workunits (times two, for redundancy) in about 8 minutes. A workunit may return in around 20-25 minutes, so it's almost impossible to build up a large queue. A fix would be to build up larger workunits (with average running time of more than 60-90 minutes) but we cannot do this until we fix the 'too big' output file issue. This is a problem for users with limited bandwidth but also for us having to micro-manage our whole storage system...

Very nice and clear explanation. Thank you! And best of luck in finding the solution soon! :-)

This cafe is completely empty!? I thought Italian coffee was the best! And so is tiramisu...! Come on, guys, an Italian project is supposed to be more lively than this! :-) :-)
