Hey EG,

This is very strange. I'm not sure what's going on here, but I will look into it.


The phrase "Use Reliable Host" might explain it all. New hosts and reawakened old hosts have zero history and therefore no reliability.
The object of the exercise is "Don't Use Unreliable Host" - can you find a parameter for that instead ?
I too would like to rejoin...

Hi Jake,
Have you any idea how many 32-bit Intel Core 2 machines there are out here ?
Many upgraded to Windows 10.
I would hardly call them
extremely old systems

If it's XP you can't support, so filter on NT 6 or higher instead of 64-bit.
Do-it-yourself solutions are NOT the aim of BOINC.

Is it possible to force SSE3 on cpu with SSE4.x capability ?

This "app_version" used to work. Can someone tell me how to find the new version ?
Thanks in advance

After seeing some of the times, I'm thinking that the "medium" length ones will probably work out the best for everyone, so figure on timings roughly around what you're getting with the 373... series.

As for the rest, I got my times wrong and Travis is flying back today, so tonight or tomorrow we should have some of the timing issues fixed.

It sounds like you know pretty well how many cycles are required for each unit. Whether they last 12 minutes or 12 hours on my P4 doesn't bother me as long as these cycles get translated into realistic (say, factor 2 ?) runtime estimates.

One thing that does bother me is that the project can apparently choose unit sizes quite arbitrarily - are they getting 60 times the science from 12-hour units compared with 12-minute ones ?
