Post:
Not exactly but you can get close. Set your resource share for Rosetta to 1 and RALPH to 100. Then after one Rosetta tasks runs another will most likely not be downloaded until you have done many RALPH tasks unless RALPH is unable to supply new tasks. You can make the difference more extreme if you want but it is unlikely make the behavior much different. The lowest that will work is 0.001. While higher numbers will work it is best to stay under 1000 on the high end.

A slight improvement on this one. This is the first version with any graphics, I can see the text now but still no picture of the atom.

Additional question on devs according to run time preferences: here at RALPH, is it better to prefer testing larger number of workunits (producing less decoys for each one, 1-5), or rather somewhat more decoys (5-15-...) from each WU, at the expense of the number of tested WUs?

Or does it really not matter?

Peter

I don't know. Here I leave the run time at "not selected". I figure that way the developers can change the time if needed.

@PieBandit
Thanks for noticing that I did not look at what the other hosts did.

@Trog Dog
I have run the graphics, no related problems observed.

I may have spoken too soon. Host has gotten about half compute errors. One of them can be ignored since it occured during a core client upgrade, however they all show the same error messages.

So are there any issues with the 64bit apps or shall I go ahead and release them on Rosetta@home?

I have a few on win x86_64 that returned successfully and were granted credit. So it is probably ok.

One point though, if the app is simply the 32 bit app renamed then it may be a better solution to update the server instead of trying to build and release a seperate app. Server versions later than 4/30/7 should automatically send the 32 bit app to official 64 bit clients. This does not help the *nix boxes now though, there is still not an official 64bit test app for *nix yet. I would expect there to be by the time it is actually released as 5.10.x.

I had several RPCs that gave no message, and no work. The most recent RPC gave the message "no work from project" and has 2 hours on the defferal. This is winxp 64.

It looks like all of the 5.38 tasks I have gotten have crashed. The output on the web page for mine is similar to what is already posted in this thread. One thing I have to add is that on a dual-core machine it was using ~98% of the CPU instead of the ~49% that it should have been.

Post:
but in any case I like the idea of throwing out 10% of the highest standard deviation.

Could you tell me why do you think the value of the deviation should be 10%, the constant?


Just a rough number thrown out. The actual cut-off would depend on how many copies are sent out and what percentage of misclaiming hosts we have on RALPLH.

Okay here is one proposal:

Send each type of WU to at least 60 hosts. Discard the results with the lowest and highest 10% claimed credit and take the arithmetic average of the remaining hosts as fixed credit/model for production runs on Rosetta.

But doesn't this way cut fair highest and lowest results at high rate? There may be some people who runs R@H on Pentium(I, II) or Kentsfield now. Especially a few users use genuine Kentsfield as testing already.

If the way would be applied, how about distributing WUs to same/similar spec's machine? This way could help the server to distinguish original claimed results from ones modified. Using coefficients figured of machine's spec, etc. I fear, however, this might be issue of client frameworks.

If thinking realistically, changing "quorum" from 1 to 3 is the easiest and more effective way applied overall. changing it to 5 isn't good:(

I don't think that idea would unfairly cut any honest machine. It may not be the best way though, since it would tend to give higher numbers than expected if there are many cheating hosts. Maybe it would work better to throw out 10% of the highest standard deviations. In that case all the results thrown out could be high if there is a concentration of cheaters, but come from both ends if all standard clients get the same task.

Any attempt to change the quorum would not work since the number of structures is user configurable.

I think the quota should be lower, 2 or 4, other than that those look like good settings for a test project.

I would think for the daily quota 2 would be the minimum and the max 4 or 8. You would want to have a chance at getting multiple tasks running on multi-CPU hosts.

Another screensaver issue for the to-do list:
If the screen is an odd shape the graphic is in the upper left corner rather than centered in the available space.
when you say odd shape do you mean unusual resolutions?

some examples if you would be so kind :)

The screensaver is in a 4:3 format. If you have a 16:9 screen it is at the left side of the screen. If you have a tall screen it is at the top of the screen. I would prefer it to be centered in cases where the screen dimension is larger that the graphic dimension.

The fix for this could also be used for the burn-in concern as well. If the graphic dimesion is made slighly smaller than the available screen size it could be moved a few pixels vertically and horizontally every minute or so.
