64-bit science apps based on Rev-2.2B code released

(1/3) > >>

Simon:
Hi,

shortly after the 32-Bit Linux app release, here are some 64-bit science apps based on the same code.

They were ported to 64-bit Linux by Crunch3r and have produced reliable and accurate results in all tests.

Performance is better than the equivalent 32-bit apps on Intel systems, on AMD systems it's not as clear; some assembly may be required.

Nota bene - Requirements

* 64-bit Linux 2.6.x - sorry, no 2.4 supported.[/b]
* glibc 2.3.4 or newer - find out what version yours is by typing "/lib/libc.so.6" on a new line - as if you were trying to execute the library itself, that will show you details about your installed glibc version.[/b]
* 64-bit BOINC client - caution: this will limit your choice of other project to participate in at the same time, because not a lot of them offer 64-bit science apps yet.[/b]
64-bit Linux science apps:

SSE2-generic
SSE3-Intel-P4/PD
SSE3-Intel-Core 2

Double the bits, double the fun ;o)

CAPTAIN FUTURE:

The Linux 64-Bit apps are faster than the Linux 32-Bit, of course! ;)

The apps are like the old S@H- V5.12 apps from Crunch3r?
That the Linux 64-Bit apps are faster than Windows 32-Bit?

So in future, if you and the optimizer team would like to do... the Windows 64-Bit apps are the fastest available then, or?

Greetings!

Sooo, since I have a pretty big cache, I wonder if anyone has had any experience switching BOINC from 32 to 64 bit in midstream?  Does it cause a problem or should I wait until the cache drains out before switching?

I'll set to no new work, but if I could switch everything now with no ill effects, I'll do it!

Hi Pam,

you'd be on the safe side to let you cache run dry. So that's what i would do.
You might also consider using a 64 bit boinc client (Agustine) provides one.

HTH

I switched from Seti 32-bit apps to 64-bit apps in midstream and have experienced no ill effects.  As usual with risky configurations, YMMV.    I suspect switching Boincs from i386 to x86_64 architecture may  have ill effects. 

Btw, make sure you test the 64-bit app and convince yourself that it actually runs and produces something before switching midstream and losing all your work  ;D
