Stats instability

Stats instability

We've been experiencing a great deal of stats instability, due to the new advmethods projects announced recently. The problem is that these WU's are just too short for the stats system to handle, flooding the system with 10x more WU's than it's used to handling. That means that instead of completing an update in 1 hour, it now takes 10hours, which is a disaster.

We're working to correct this, but it will likely take a little time to get through the backlog that's been generated.

New rules for advanced methods (-adv flag)

In the near future, we will be releasing some new projects which require a very rapid turn-around time. These are peptide fragment simulations which we are interested in simulating for a time-sensitive collaborative project involving protein structure prediction.

These WUs will go directly to the classic clients running with -advmethods. Non-classic clients (eg SMP, GPU, PS3) will not be affected, as all of these calculations will be run via the AMBER core and only the classic client supports the AMBER core.

To reward users for participating in this exciting project, we will be giving a x1.5 bonus in the points awarded. What's the catch? These projects will be less rigorously beta tested, so there will be an increased risk of Early_Unit_End errors. We believe the risk of this is minor (there will likely be a higher rate of early unit ends, especially very early in the WU, but we do not expect client machines to become significantly less stable). However, if you do not wish to participate in this project, just remove the -advmethods setting from your client.

This will not last forever and will likely go back to normal -advmethods usage in a few months. With that said, we do plan other uses for -adv in the future.

Note: the text was updated to clarify that this is classic clients only.

So, any opinions on whether we should continue with SMP or go for the x1.5 with the oldschool client's advanced method?

No idea yet. Just test it, run the standard, see what your PPD is, and compare it to what you get on the SMP

I added the -adv flag where?

advmethods not -adv

Can I assume these new projects are whats effecting my PPD and daily/weekly WU count?
My PPD has went from the 500 - 600 range to as high as 1000+
and my WU weekly count has went from 30+ to 100+ in the last couple weeks.
