Looking at users Robetta and Kel's computers - their RAC per computer is fairly low (dual xeons with racs of 30/day).

Is it because you guys don't crunch for Rosetta full time, or limit the CPU usage? Just curious :)

We are running on the desktop computers in my group. BOINC is idle when we are doing calculations--for example, my machine has been busy trying to analyze all the 1hz6 data generated over the last several days!

So, it not the fact that it's running a Linux client?

Then why is it when I was running Linux I was only getting half the results that my Windows machines get?

The reason I'm asking is hopefully, by next week I will be running Linux on at least two more my machines(I changed them to windows to get the highest performance I could in Rosetta). Is there anything I can do to help get the performance on the Linux side of things to equal the Windows side?

The rosetta boinc source code will be available soon for people interested in helping with debugging and optimization.

Also, we have it set up to stop when the computer is in use.

Thanks David & David - that makes sense :)

Cheers!

The Linux core client is not optimized as well as the windows one. Therefore, the benchmarks it calculates are about half what they should be. That equates to about half the claimed credit a windows machine would ask for.

Some Linux users (myself included) grab the source code and compile it ourselves so we can add the proper compiler options to optimize the code. A few people make optimized clients available for downloading for those that do not want to compile it themselves. Try these:

http://www.pperry.f2s.com/downloads.htm

I still run 4.72 on my Linux box. I can't compile the 5.X series yet as I need to update the curl libraries on my Fedora Core 3 system first. I have not yet found any compiled 5.X clients out there yet.

This will not make your machine crunch any faster since the core client's speed has nothing to do with any particular application.

Hope this helps.

This is wonderful news! Let's hope we can keep you very busy analyzing a vast quantity of results! ;)
