Message 8664 - Posted: 19 Jan 2009, 16:06:06 UTC

I thought it be better to have them in one place...

Linux 32bit:

SSE

SSE2

SSE3


Linux 64bit:

SSE3

SSSE3

SSE4.1

All compiled with Intel icpc from the original code.
All tested against the test wus and giving exactly the same result.

Please report any problems here.

What kind of speedup did you get on these compared to the stock app? And did you use any specific compiler flags?

Can you make them AMD compatibel?
I just tried it out and it didn't run of course. :-\

This host is runing the SSE41_64 version. But I don't have numbers for stock...

Temujin posted numbers for the 32bit versions.

And here are flags:

CXX_i686 = icpc
CXXFLAGS_i686 = -xSSE3 -O3 -ipo -no-prec-div -static -fp-model fast=2 -fp-speculation=fast -opt-calloc -unroll-aggressive -opt-multi-version-aggressive -fast-transcendentals

CXX_x86_64 = icpc
CXXFLAGS_x86_64 = -xSSE4.1 -O3 -ipo -no-prec-div -static -fp-model fast=2 -fp-speculation=fast -opt-calloc -unroll-aggressive -opt-multi-version-aggressive -fast-transcendentals

Due to the v11 release I removed the apps from the server.
New ones soon. :-)

Stickying this because i think it's something our linux users would like. Also, the linux optimized apps seem to have been returning good results :)

Good to hear, I hope the V11/12 sill does. ;)

The SSE41_64 already running on my Q9550, I'll post it (and the other SSE levels) when it still gets credits tomorrow.

Things look fine on my end, it will be getting credits tomorrow.

I suppose the question then has to be asked.

Why are the linux opt apps giving good results, but the Win ones are causing a load of trouble? Is it a compiler flag difference or code change?

And I'm sure there are a lot of Win users (and maybe MAC users too) who would like to have similarly optimized apps (that return good results).
Never surrender and never give up. In the darkest hour there is always hope.

Any code change from my side, just compiler and flags (posted below).

New recompiled apps for Linux64 on Intel:

SSE3_64


SSSE3_64


SSE41_64

It seems they don't run well on AMD, so it might better for AMD users to try a testfile in standalone mode --> look here

Please report errors (and success) here.

Just completed and validated my first WU with the SSE4.1 App.

Result here.

Running Linux-Ubuntu 8.10 64-bit, Q9450@3.4GHz, WU took 683 secs.


Looking good Mic

Hi speedimic,

THX again for the great work!
My Linux quad likes the SSSE3 app very much... ;-)

Xubuntu 8.10 64-bit, Intel Q6600 @ 2.4 Ghz

Each WU needs ~18-19 minutes on that host and no errors so far! :-)))
Lovely greetings, Cori

As I told here, I have some problem with some wus only with SSE4.1 X86_64 app !

I don t know if it's the application or the new assimilator/validator :/

Well, of course not. The Intel compiler runs degraded code when run on AMD processors. The highest SSE level that it runs on AMD processors is SSE2.

Linux and OSX seem to be returning correct results (ie. those in line with the stock app). For windows, it seems there are 2-3 different strains of bad applications out there.

Message 8831 - Posted: 22 Jan 2009, 1:43:02 UTC - in response to Message 8762.  

How do you install these clients in Ubuntu64?

Tried replacing the stock opt app in /var/lib/boinc-client/.. but it errored out.
Where to place the app_info.xml?

Guess i'm not following the right steps?

thx

The SSE3 code runs very well on AMD LE-1600, like C2D with the same clock.
I use icpc -xO for this.

First stop the service ( /etc/init.d/boinc-client stop ), then put the files from the zip (app_info.xml, milkyway_0.12_SSEwhatever...) to /var/lib/boinc-client/projects/milky..., then restart the client.
