Anyone know of any good SSE (not SSE2-SSE3) enhanced BOINC/Rosetta clients for linux? Most of the ones I've come across only work for SSE2 or SSE3.

Thanks,
Justin

Gooooood question!

Stab in the dark....will the mac version run on linux? Afterall, the mac version is unix, right? Not talking about the GUI, but the CLI exec.

Very unlikely. Mac OS X is based on a unix derivative, but I've never heard of any programs that would run on both platforms without being recompiled. You've got different libraries, among other things.

My german isn't very good....

Also, try this one. It looks like it starts out all about windows, but has links to linux too:

I did install the 5.5.0 SSE version from the first link, but I kept getting errors when reporting results. I was never actually able to report a single WU.

I don't see any linux stuff on the second page.... I actually went through the page earlier today and couldn't find anything then either. I guess I'm just blind.

I'm trying it right now (with ubuntu). I'll let you know.

Did you make sure you had all the libs (the README provides a command to see)? I found I was missing 2.

The first link also has links for 5.2.14.

While I have the attention of someone who knows...

What's the difference between SSE, SSE2, and SSE3? I understand it has something about the CPU, and maybe Intel specific. But that's it.

Understand that Rosetta is a bit different. Job completion is based on time, not work. The default is ~3 hours.

After updating, one of the two jobs running immediately reported in with an error. The next one finished about 14 minutes later, sucessfully. Same for the 3rd job.

To recap: 1st in process job failed. Next two worked. I'll let you know if there are more failures. Otherwise, assume continuing success.

It's a Pentium D 940 (2x3.2ghz w/ 2x2MB cache), running the latest ubuntu, with all updates. I also had to add a couple of libraries according to the README.

Oh yeah, this was was with the SSE version. Would the SSE2 be better? Worse? Not work at all?

And what's up with the 5.5.0? The latest BOINC version is 5.4.9. So what does 5.5.0 refer to?

[JustinHoMi]

If your processor supports SSE2, then yes, it would be faster. Type "cat /proc/cpuinfo" and look for "SSE" and "SSE2" at the bottom. My guess is that the Pentium D would definitely support SSE3.

I don't know what the deal is with 5.5.0.... Maybe it's just based on the current code from CVS.

[zombie67]

Update: SSE2 is much faster than with SSE.

JustinHoMi: What kind of CPU and/or version of linux were you using when you got all those errors?

Up until recently, I had been working exclusively with intel and Ubuntu.

I recently aquired an AMD Athlon X2. For no apparent reason, I decided to try out SUSE for a change. I installed the 5.5.0 w/ SSE2. Almost all the results were errors. I tried down grading to the SSE version. Same thing. Then downgrading to the stock client. Same thing.

So I installed ubuntu instead, and SSE2 verison of 5.5.0, and it worked like a charm. No errors.

So maybe the problem was SUSE. I don't really have enough samples to know for sure. I do know this: Ubuntu with both intel and amd works with 5.5.0 for me. Perhaps you should try Ubuntu?

Here is the odd bit: I thought AMD would be significantly faster than Intel (even at a slower clock speed). But this is what I have found:

Pentium D 940 (3.2ghz): mid 10k sec = ~105 credits
AMD Athlon X2 4200+ (2.2ghz): mid 10k sec = ~90 credits
Pentium D 820 (2.8ghz): mid 10k sec = ~85 credits

So yeah, it is faster than the D 820, but I thought it would also be faster than the D 940 too.

SIMAP have recently issued a new Linux version. How does that work as a comparison?
