@ KWSN
It really didn't like parallelization. Came up with quite a few critical errors during rebuild. whoops :)

Well, there goes that idea then :o)

I haven't had time to test single-threaded builds yet. Instead, I was working on releasing a Linux SSE-optimized version alongside my already released SSE2 version.

So guess what, it's online :o) Check the announcements thread for a download link.

Regards,
Simon.

Thanks Simon! What kind of speedup do you see with the SSE version?

Depends a lot on chip type -

a P3 600 had a speedup of ~25%, several P3 700s and 1 GHz had a speedup of around 15-20%. It seems to depend on which exact P3 model you have (there were several, including some slot-, not socket-based ones).

On my tiny little AMD Duron 1200 (it has only 64KB cache), the speedup is around 8-10%, so not really as big.

Your mileage may vary :)

In all my tests, I have found it to be quicker than Crunch3rs Linux SSE version (only could test on my own hosts though since I'm not distributing that to anyone).

HTH,
Simon.

I've just got XP's so it'd probably be somewhere in between that and the P3 numbers you mentioned.

BTW, I'm not to familiar with running UPX'd applications. Do you recommend the UPX'd app over the uncompressed one? What benefit besides loading time does it give?

Thanks,

The only reason I compressed the executable is cosmetic, because it takes less diskspace that way. Uncompressed, it's around 12 megabytes large.

There is no performance difference between using the UPX-compressed or uncompressed binaries. Some people have reported problems with the UPX-compressed executables, which is why I'm offering two versions. I wonder whether anyone would care about 9 megabytes of disk space difference...

In the future, I may either figure out how to make smaller executables or just leave them as large as they are, uncompressed, so there's only one version for download and less possibility for confusion.

HTH,
Simon.

Oops!

When I uploaded the files, they got the wrong extensions. So they were named .tar0.gz and .tar1.gz - this is now fixed. If you have already downloaded the SSE-optimized client, just rename your downloaded file (although tar should not care about extensions, really).

I've edited the files online so the file names are now correct. Any new downloads should be okay.

Hi Chicken,

quite interesting what you've done here...

Been vistiting this board after some weeks (months?)
And i've been impressed on what you've achieved thus far...

Anyhow to add some clearance... you cannot compare any of my builds to the latest source or client you've done...

My apps. where build from a 5.07 soure code basis and there've been some changes recently if i read the board ( on the fly) correctly.

Did some builds using the stock source on linux ... tested you app. and it did Joe Segurs. quick ref in 318.sec .. mine took 301.sec... (without any special improvement to the source...)
P.S to answner some questions ... my build didn't use default soure code and were modified ;)

Still some room for you to optimize ;)

P.P.S.

Don't know what you did to your app but its 3858091 bytes (allmost 4 mb) WHY ?

Take a look at what your linking against... remove unecessary stuff...

The defaults static app using ipp (the one i've build out of a wimp) is 1806608 bytes and not any byte more.

Go ahead and do some faster app. ;) ... if you can ;)

Thanks for posting :)

Yeah, I did not modify any of the sources related to performance (only some slight syntax errors/CVS checkin oversights). I do realize there is a lot more headroom for improvements here.

As the versions you released were the only ones I had to compare (and yes, I was/am using them and they are great :O) ), those were the ones I used. My real motive behind this was to make it easier for the average person to help themselves should noone else decide to release optimized clients.

Also, your binaries were not static; instead, they linked the Intel libs statically and were dynamic otherwise (ldd said so, anyway). I tried compiling a real static binary but am having trouble making that run - it keeps giving me an obscure error when I run it (something or other malformed on line 1). Like I said before, I really can't code C/C++, so I'm limited in what I can do :o) Yet another reason for me to make the How-To so maybe someone who can, will. When I compile the apps using -i-static, they are 1784944 bytes large.

So because I could not make a real static binary, I used statifier (statifier.sf.net) to make a "fake" static one, then UPX to compress that one...still way larger than a real static binary.

Let me thank you for all you've done in the past for Seti@Home, your work is not forgotten or in vain.

Und auf deutsch: Deine Apps wären mir lieber gewesen als selber welche machen zu müssen :o) Aber es ist gelaufen wie's eben gelaufen ist, sehr schade.

Regards,
Simon.

Don't know of what troubles your takling about reagarding a staitic build. Hmmm...

The one i did from the std. source is a fully static app. ( as previous releases where dynamic builds .. the linux ones where if i rmember corectly S@H enhanced 5.05 code basis).

Another thing i've notticed ... read that there are some complaning that the stock source won't compile on gcc 4.X... don't know what your'all doing but it works the way its supposed too...( Doesent' matter if gcc 4.1 or 4.2 is used)

P.S.

Why do you link MKL ?
It's useless and slower than fftw 3.1.1...

TIP

remove all references to fftw3 ... it's useless and on 90 precent of the tasks slower than ipp.
( in some cases as you've noticed fftw3 is faster than ipp(stock app) but that's a case you've all have to live with... in 95% using the std. angle of 0.42XX the ipp app is way faster than the stock app. and that's the case that matters... ;)

Thanks for the hints :)

I'll take your word for MKL being slower than fftw, since I really have no basis for comparison.

I have an indecent question: is there any chance you would publicize your LDFLAGS/CFLAGS? Everyone doing optimized builds could benefit. Like I said, an indecent question :o) We can hope, anyway...

Also, did you use ICC or GCC? I've been using ICC 9.0 (IPP 5.0 of course as well - did you use 9.1/5.1?). I have so far not tested any builds with GCC and IPP, but that's in my plans.

Not needing ICC or MKL would drastically cut the required license costs, I could afford the license for just IPP on my own (for Windows, since Linux is doable with the free non-com license).

Regards,
Simon.

You can count on that.

Short answer .. NO... due to some reasons in the past..

Also, did you use ICC or GCC? I've been using ICC (IPP of course as well). I have so far not tested any builds with GCC and IPP, but that's in my plans.

Only used ICC...

ICC or ICL on Windows is required to build the app. MKL is useless for S@H...

TIP

Read that someone claimed that i did/ could not afored buying icc & ipp license for a year...

I find it hard to believe that Crunch3r was paying $900 US every year just so he could make BOINC and s@h optimizations!

Well there's a half year left until the license expierces...

But anyhow why do people care on what i spend MY MONEY ???

Do you know anything of the total costs to build the previous apps. the none enhanced apps. that you're all enjoyed before and downloaded for FREE ???

You really want to know how much and who did a donation to releave the costs from my own ???

Exactly - someone asked me the same, and that's what I told them. Nobody's business but your own how you spend your money...

Since I've been doing work on this, I can imagine how much time in total you must have spent on all the optimized apps you made. Massive doesn't begin to describe it. Nobody here could afford that kind of money if they'd have to pay you for it...

I can understand your feelings about not releasing anything, I didn't have high hopes there anyway ;o)

So I guess it'll have to be ICC and IPP for Windows. Still better than MKL as well.

Thanks again!
Simon.

I'm still mucking around with the seti source, in case you're wondering.
My latest attempts resulted in a remarkably slow app, but you'll know this goes :o).

I'll drop you a line if something comes from this.

P.S: Not fried yet, but I didn't release any binaries 'till now :o)
