Crunching tips

dddt workunits shouldn't take that long.
Something looks wrong with that WU. Cancel it .

Does GPU´s boost WCG at all?
If I put few GTX 295 or 9800 GX2 cards to cruncher does it make any difference?

WCG doesn't have gpu work units. you'll have to ad gpugrid.net to your boinc manager if you want to crunch on your gpu's. and the points dont go to wcg, they goto gpugrid. see the points in my sig.

In case you'd like to extend the 1st post, here are some ideas...

- don't forget to set CPU usage to 100% in BOINC after creating a new user, still only 60% default
- 64bit OS boosts PPD by about 10% over 32bit OS
- on Core i7, enable HT for around 40% boost in PPD :eek:
- on P4, don't enable HT :p:
- best bang for the buck cruncher currently seems to be an i7 920 (D0) or W3520, Gigabyte EX58-UD3, cheapest 3x1GB DDR3 kit, either no GPU at all or a GTX260-216 for GPUgrid or FAH, and a decent PSU in the 500W range

I am sure there is more, but these are additons that come to mind.

Re-read the first post.

Oh right. Anyway, you still might want to think about extending that 1st post some time... I know you are real busy tho so no hurry :up:

Read this too late, but I am curious about the performance differences...anyway the p4 will be going back to work in a couple of days and with no internet :( ...Need the best way to close out use of this one

you can put the following lines in the file cc_config.xml.

Code:

<cc_config>
<options>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>

The code will force the system to immediately report your uploads. Otherwise it might take some time.

The file is usually located in the user boinc (data) folders - depends where you put it when installing the client. If you don't know do a search for file "stdoutgui.txt" - cc_config is in the same folder (if not then create).

Points are only granted when the WU has been validated. Depending on the project that maybe (almost) immediately or when the wingman return the results.

Thanks for that, what a relief. Now I don't have to manually update 100 WUs or so all the time.

So I created a text file and put the above text in it and put it in the Boinc folder-will that do the trick?
