Please help! I cannot get any

Please help! I cannot get any new work.

Here is the error message I receive:

2007-04-23 13:23:25 [Einstein@Home] Message from server: To get more Einstein@Home work, finish current work, stop BOINC, remove app_info.xml file, and restart.


I did exact that - it downloaded version 4.16, which is much slower than 4.27. So I reinstalled BOINC 5.8.17 and also reinstalled 4.27. I reset the project - no go. Same problem.

What can I do to get 4.27 running again?

Build a time machine? You would need to go back about a week, to before the recent S5RI run issued its last workunit. Read the various threads about S5R2: the current app you're downloading - 4.16 for PPC - was rushed out in an un-optimised state so you would have something - anything at all - to crunch on. If you follow the advice, and remove the app_info.xml, you'll get newer, faster applications during the course of the run as development work proceeds.

the 4.27 app is for s5r1/s5ri

the 4.27 app is for s5r1/s5ri which is the just finished science run. The 4.16 app is the one for the s5r2 run. You need to remove the app_info.xml file so that the 4.16 app will run.

The application name itself is changed, but starting its version numbering from 4.0 is somewhat confusing. The s5r2 work units are significantly larger than in s5r1 so will take several times longer to complete, although since the application is completely new and not as fully optimized runtimes should decrease in the future. Credits per WU should be somewhere in the 100-400 range depending on size. In addition, credit per hour in s5r1 was significantly higher on einstien than in almost every other boinc project and was reduced as a result. On windows platforms the reductions are ~40% on AMD systems, 25% on intel. Noone's posted any numbers on the performance shift on a mac system yet.

Is there any

Is there any progress/activity going on for optimized apps for the G4? I have a PowerMac G4 2x1ghz machine and on Seti the optimizations have nearly doubled its performance from the stock app, could the same thing be done for a G4 in Einstein? I'm assuming that the optimized app for the G5 won't run on a G4, is that accurate?

There are no current optimized apps here AFAICT, for any platform or CPU. During the S5R1 run a G4-optimized app, v4.26 IIRC, was beta-tested and then made standard; the G5-optimized v4.27 remained separate and only available by manual download—and yes, it contained processor-specific code that would not work on a G4. I assume the development for S5R2 will follow a similar course.

(I’ll be removing my v4.27 on this G5 as soon as I get a chance to stop BOINC; at the moment it’s got a couple of SzDG tasks on the go. It could be two or three weeks before this host gets any E@h work.)

Hello, witch compiler are use for the actually S5R2 app (for each CPU/OS)?
And is the autovectorization use (For Each CPU/OS)?

-OS X PowerPC gcc 3.3 or 4.0 ? autovectorized ?
-OS X Intel gcc or Intel compiler ? autovectorized or vectorized (in the code) ?
-Windows x86 gcc or intel compiler ? vectorized or autovectorized ?

And what will you do on specific optimized app for mac ? (compiler, vectorized/autovectorized, flags ..)

I noticed that my G5 1,8Ghz is as fast as an windowsX2 1,6Ghz (compared one core to one core) so it's not very good but it's not catastrophic too.
And a Macpro 3Ghz (so OS X) is 2,3 faster than my G5 (compared core to core) and
at same clock frequency 40% faster.(20% compared to Turion X2)

You mean news about optimization?

I was speculating earlier that only Intel and AMD CPUs will benefit significantly from the next round of optimization, but I now think I was wrong.

From what info is available to the public, you can see that the devs are trying to re-arrange the code in a way so that modern compilers like gcc 4.x would be able to auto-vectorize it. On a PPC this would mean Altivec !

Bernd and Akos will know more, not sure they are willing to share that info at this moment, tho ;-). I guess it all comes down to: it's ready when it's ready.
