Something wrong on my end? Never saw that error before. XP 32 bit.

Tried getting new tasks on second machine. Same error. Win7 64 bit.

The same HTTP permanent error.
No WU for application v.101.00 was downloaded - all generate errors.
But the application itself was downloaded ok.

That's the issue we've been having ever since the server crash. The server has a heap of work on the database but the actual files aren't there because of the server crash.

Of the few work units that I have managed to download the 101 app is about one third faster than the 100 app (both sse3 versions).

Is the apps source code available for download somewhere ?

Less (if any) for the Windows x86 version on C2Q, my Xeon (i7 generation, Windows x64) seems to have gained ~1/4 speed

Of the few work units that I have managed to download the 101 app is about one third faster than the 100 app (both sse3 versions).

Now I have a larger sample I would have to say they are taking a little longer. Not by much though. It was about 30-32 mins before, now about 33-35 mins.

A little faster.

Xeon E3-1225 v2 (4 Core / 4 Threads):
- v100.00 SSE3 => 1200-1300sec
- v101.00 SSE3 => 1100-1200sec

Xeon E3-1245 v2 (4 Core / 8 Threads):
- v100.00 SSE3 => 2200-2350sec
- v101.00 SSE3 => 2050-2200sec

Searching a BOINC-app for my tablet - such that: It has maximum integer computations and minimal FPU computations from all those apps available for BOINC on Android. :-)

Any advice, please?
Thanx.

Mám dotaz:
Ve výpočtech Asteroids at Home aplikace pro Android: Převažují tam

integer nebo FPU výpočty?

Mám tablet, jehož ARM 1.0 GHz CPU má výrazně rychlejší int. a o 20 procent pomalejší hardwarové FPU (než můj ARM-CPU *TAKÉ* 1.0 GHz, ale v mobilu).

Hledám pro něj tedy vhodnou aplikaci, která by měla co největší podíl integer výpočtů - ze všech dostupných BOINC projektů pro Android... :-)
Děkuji!

The new apps seems faster on Pentium E2200 and about as fast as the "old" app on Athlon II 240.

99% calculations in Period search app uses double precision floating point operations.

Thank you.

BTW: Do mobile processors ARMv7 (v7 rev.2) have *DOUBLE* precision floating point instructions in their hardware??? I am surprised! :O

- they must have, otherwise it would not be efficient and no sense in making Asteroids app for them.
But it clearly runs on some hardware FPU, because 1 WU on 1 GHz ARMv7.2 CPU (Snapdragon type) is completed in less than 18 hours.
:-)

Will there be new compile for Intel MacOSX with SSE2/3 instruction sets?

Thanks!

Yes, when there is no new other versions of SSE, because I have have to send it to someone else for compiling.

Wonderful!

Thanks Radim!

SSE3 ver. rocks! It completes avg.in:
53 minutes on 3GHz AMD A8-3870K 8GB DDR3 @ 2262 MHz,SSE2 in 60 minutes.
98 min. on 1.6 GHz Intel i7 720QM, SSE2 in 101 min., "Period Search Application v101.10" (no SSE) in 206.48 min.

778.5 min on 1.6 Ghz Intel "Atom N270", "Period Search Application v101.10" (no SSE) in AMAZING 2075 minutes.
(Does anyone from Asteroids-at-home have "INTEL C++ compiler / ICC ver.12" to make an Atom-SSE3 optimized version, please? I cannot find any up-to-date and optimized computations for my 2 Atom devices :) )

Android-apps:
842 min. on HTC One-V, 1 Ghz Qualcomm(Snapdragon) "ARMv7 Processor rev 2 (v7l)"
2072+ min. (computation ERROR at 85 percent!!! WU: http://asteroidsathome.net/boinc/workunit.php?wuid=6094290) on "POINT OF VIEW Mobii ProTab2 IPS 9.7", CPU "Cortex A8 1.2 GHz".

Please, can someone try to make a "Cortex A8 ARMv7 Processor rev 2 (v7l)"-compatible version of the app ? I am afraid it might have no hardware-DOUBLE-PRECISION floating point instruction and it seems to emulate it really badly. But maybe there is some other way around it... ..... like a proper emulation written directly in the code? I dont know if it is possible... :-)[/url]

OK now. First WU completed on ARMv7 Cortex A8 , in 37.75 hours:

I don't know why, but my SSE3 PCs downloaded few vanilla units after the new app versions were released. I cancelled those units and the next batch was SSE2 or SSE3.

The BOINC server tries to work out which app is faster. It does that by trying a number of work units using each app. Once its got an idea how long they take it can then give you work for the fastest app.

I got some vanilla 101 as well as the SSE2 and SSE3 versions when the 101 app was first released. While they can be annoyingly slow (well the vanilla app was) if you just let them run the server will quickly work out what is best for your machine.
