This App incorporates SSE vector code, but doesn't have a CPU feature detection. It will badly crash on non-SSE machines.

Other calculations are done in x87 FPU math, including the linear SIN/COS approximation, which should make it run (and run fast!) on older CPUs (i.e. PIII).

This is also the first Linux App featuring graphics in a separate program - it doesn't need any resources if you don't run it.

Only run this if you're sure of what you're doing.

Find it on the Power User Apps page.

Happy crunching!

GNU/Linux S5R3 "power users" App 4.27 available

4 machines switched to linux from windows, updated app from 4.24 - 4.27, set other projects to NNT/NNW, and atleast one has started running with the new app(from scratch). No problems yet.

I've switched a couple of my P-III's over, and and continue with the rest of them once my felines quit demanding my attention.

Thank you, thank you, thank you!!!

As the owner of a large number of SSE capable PIII tualatins and Athlon XPs which are running Linux, I'll be in hog's heaven with this app. I've just converted a tualatin now which was running 4.14. It has restarted with 4.27 after I added some lines to app_info.xml to allow the old 4.14 version to be handled by 4.27. There were no problems with the transition but it'll be a while before the new speed becomes apparent.

As a general warning to unsuspecting users who might be tempted to use this app, please be aware that if you are currently running a version of the app that is older than 4.20 (eg 4.14 like me) and want to switch midstream to 4.27, you will need to make a small addition to app_info.xml to make the transition happen smoothly.

Otherwise any tasks in your cache that are "branded" with a version older than 4.20 will be trashed.

Cheers,
Gary.

Please tell me you didn't switch the 6000+.... That will make the Linux side extremely fast compared to the Windows side... To baseline the standard apps, it has to be a 4.20 vs. 4.15 or 4.24 vs. 4.25 comparison...

I installed the new 4.27 Apps on 2 Linux machines and as soon as I restarted the client, the 4.21 apps disappeared out of the project folder, but old Wu's are still showing as running under 4.21?

Brian, As I understand it....to do a "proper" evaluation of cpu times and credit (as both fluctuate given the freq and task number) that one must have atleast a full cycles worth of data per host per OS. Given the hard work Bernd appears to be putting in pushing out these new apps and the frequency of updates. It's not likely I'd be able to get that baseline (at least with Windows). I hadn't thought of ever running the stock version of linux. Basically, I need to get a bunch of data from some app, atleast enough to convincingly show the height and frequency of the curve. I have just today, set my linux machine to 4.27 and other projects to NNW so that I might get enough of them. Looking at the massive amounts collected by Richard and others, I doubt I'll ever get that many. Heck, given the run times of these wus and the number of consecutive tasks needed to display it, it could be months before I have anything workable. Currently my machines are 4.27 when in linux and 4.15 (stock) when in Windows, but the next time I reboot, I'll be moving to 4.25 or whatever is next.

Basically, I don't think I'll be able to do that analysis properly, so I'm resigning myself to beta testing and whatever else I can analyse.

brian, this is OT, let's continue on the S5R3 thread.

On the display of the boinc manager?, or in some process viewer like "Ksysguard"???

mine shows the old app in the boinc manager, but process viewer shows 4.27.

I only run the client on the machines and control them with BoincView, which tells me its running under the 4.21 apps. The top or ps -AL command cut of the process name right after the 4, so I can't really see.
Anyway to get it to show me the full name?

Sorry, found a Gnome program to show me the processes, and Yes they are running under 4.27 :)

ps -f -p
