Here's the first unit crunched, there is one other unit reporting, But It was an invalid WU made by a Pentium M(1.86GHz). It still has not been validated yet, But at least It's not errored out.

This does not look like it is being tested on the beta site - is this a production release already ? Or should it be tested on Beta fully before allowing it to be used in production ????

Great to hear it's working, very sorry about that mix up. Again, I'm not sure what the speed difference will be. On my machine, I don't see a significant difference over Simon's (awesome) optimized app that this was based off but hopefully it's a start.

Simon, Sure I'd like to work together. There's some more I want to change in the code base to make it totally cross compatabile with 32-bit and 64-bit builds. There's also still a bit of warnings I want to check into. This was just a rought edit to get valid results and check initial performacne since I'm kinda time limited with school atm. As long as it's not any slower than the 32-bit apps, I hope it's an ok start.

Again PLEASE remember, this is just a test. Make sure you do a test run first on your platform with test work units before you try it on the actuall BOINC app!!!

Thanks,
--Bob Delkhoon (DeNitro)

Great :o)

I've given you access to the pre-release and development boards on lunatics.at, check your personal messages there for more information.

Running a benchmark (offline) of your version vs. mine currently, will let you know the results. The second build you posted now runs fine on my system.

Regards,
Simon.

<edit>
Run results indicate that your app is quicker on some WUs and the same speed on others as my 32-bit ones. Great work! All my test WUs had valid results.

Optimized SETI@Home apps + Information

Benher mentioned that the code is not taking good advantage of the all the registers available in the IA32 or x86-64 architecture. Fixing this might require non-trivial understanding of the source.

I think when Ben originally said this, he wasn't implying that it was a problem to be fixed. :) A lot of SETI code is simple loopy code, and there are arguments against doing a ton of loop unrolling on Core2, like a 64-byte loop buffer and the increase in code size that you've taken by moving to x86-64.

Hey Alex,

Can you think of a function that might benefit from 16 x 4 simd regs (in seti)? Would it keep the register pressure down somewhere? Your most complex simd seti use seems to be your chirp sse3, but compiler seemed to use only registers and not store values in temp memory when I looked at the assembly output.

=Ben

Thought you guys might like to know, not sure if its my comp or the app, but I have gotten a few "client errors".

stderr out is as follows:

<core_client_version>5.4.11</core_client_version>
<message>
Incorrect function. (0x1) - exit code 1 (0x1)
</message>

Hi. Haven't been back to the SAH for a bit and know I find this :).

I've grabbed the app and have started full testing for validity and run time with Kna's nice benchmark tool. Ive used the Imagecfg tool to limit it to one core as have been doing for the other testing.

I'l just let it run and let you know how it goes.

Nice Work :D

Heres a full copy of the full test run results. Included in the run is KWSN's sse3-1.3-p4 app and Bens test sse3-xP-ipo-ben-B as they're currently the fastest on this machine. This give somthing to compaire times to as well as the Default 5.15 app.

All results where Strongly similar.

Thank you Bob (DeNitro)

Thank you guys for the feedback. I believe I've been able to pull a little more speed out of the 64-bit app. It's hard to tell from the quicker test units how much faster it is but the results were valid. I'm going to run the client overnight to see if there's a noticable speed difference and make sure it's all ok. If it checks out I'll probably submit the code over on Simon's developer board tomorrow.

Side note: It is supposed to be "EM64T", sorry about that. Got it mixed with AMD64 =)

Thanks,
Bob Delkhoon (DeNitro)

It runs faster on the Intel machine then on the AMD. If anything it slowed down the AMD so I removed it.

Running great on the intel machine.

Can you think of a function that might benefit from 16 x 4 simd regs (in seti)? Would it keep the register pressure down somewhere? Your most complex simd seti use seems to be your chirp sse3, but compiler seemed to use only registers and not store values in temp memory when I looked at the assembly output.

Had you not brought up my SSE3 chirp, I would have said the same thing--the main loop's data dependencies aren't particularly serial. Given the length of the loop, I can't guarantee how well x86 processors will schedule around instruction latencies, so if I had extra registers, I'd try unrolling it wider to see what effect it had. It's still less certain than on PowerPC, where I'm dealing with an in-order vector unit and can tell what's a win just from examining the generated assembly.

As for the rest of the functions, I doubt too many of them would benefit much, if at all.

[...]
So, EricVonDaniken, have you signed up on Simon's board yet?

Yup, he just did.

Eric, you've got access to the pre-release forum now. Check back on lunatics.at, you will see an extra forum category (as well as an extra Downloads section).

Regards,
Simon.

Hi Joker,

interesting that it's returning invalid results - haven't had many reports of such things happening (other than from massive overclocks that went just that little bit too far). Are you sure it's the 1.3 app? The 1.2 and 1.3 only differ in that 1.3 adds CPU MHz detection, not in any other significant way. The function used is part of IPP, and seems to work reliably enough.

I'll check out your registration troubles and manually unlock your account. Sorry it's got to be a bit complicated to sign up - there have already been a few unsavory spam messages posted before, so now there are a couple of measures against that in place, of which the registration confirmation is only one.

Should still work, but sometimes it just doesn't :o)

Regards,
Simon.

Hmm, ever since I installed the 1.3 version of the sse3 app on my computer, not one invalid result. This is on a Dell computer, p4 2.8ghz 512mb RAM with Winxp Home SP2. Crunching like a mad man. Question tho, on CPU-Z, under the instruction set, it lists that EM64T. Do I need to be on a 64 bit operating system to take advantage of that function, or can I do anything with it being on 32 bit?

You need XP x64 at the very least, No 32bit XP OS will run a 64bit app or program.

Ahh, ok. Thanks. I just wasn't too sure. Don't know enough about all that stuff. Hehe. Thanks again.

I compiled a second test. It will probably be the last test I put out. I'm going to post the code over on Simon's page and most likely just submit changes to him there to keep things organized. The results seem pretty good so far.

This build is about 80% smaller and 5%-6% faster on the tests I did.
http://tiger.towson.edu/~bdelkh1/setiathome-5.15-DeNitro-em64t_test2.rar

Results may very, I only have 1 x64 machine to test code on so it's hard to tell how it will run on other CPU types.

PLEASE make sure to try this on a test work unit and validate the result before putting this into BOINC!

Hey Simon, Your 1.3 SSE2 Generic has handed out Invalid Results, I went back to 1.2 on one PC and may on the other one that is using the 64 bit app made by Bob If It makes any more Invalid Results and Yours did 4 in a row.

I also tried registering for an account on Your forum and I tried both My email addresses and somehow both don't like Your confirmation emails and so I can read, But not login or post.

This most likely doesn't apply here, but a few months back I had one of my machines that only crunches start randomly giving out errors. I ran Memtest86 on it to test the RAM and sure enough, after running for about 30 minutes I saw errors start appearing. There was only 2 sticks of ram in the system so with trial and error I figured out which was bad and left only the good one in. It's probably a slim chance the RAM is the problem, but it's pretty easy to check with that software.

Thanks,
Bob Delkhoon

Joker,

again, the only code change from 1.2 to 1.3 was the insertion of CPU MHz detection.

There is no "1.2 Code base" as such :o)

HTH,
Simon.

In a word, no.

I'm sorry you're having trouble with it, but - 10005 Windows app downloads say differently.

I won't remove that code, as I find it pretty useful. In fact, there will be a little more and more specific output in a future release version about your CPU and its capabilities.

Should you need any specific 1.2 release version, I still have the .exe files.

Regards,
Simon.

Okay,

I'll say it a third time: the only difference between 1.2 and 1.3 is the addition of the CPU MHz output.

There is no 1.2 source archive online anymore.

In analyzeFuncs.cpp, search for "KWSN".

In the code block following the first search hit, you will find something like

#ifdef USE_IPP
[3 lines of code]
#endif

Remove them including the #ifdef and #endif lines, you're now at 1.2.

Regards,
Simon.

I've been working with Simon and a few guys on his developer's board. They've been working on some great optimizations to the seti code. I've been incorporating the changes into 64-bit builds and doing testing on them. I don't have any kind of timeframe on new clients but the progress is looking very good.

Good to know, Until then It's full speed ahead on the 64bit road for one of My crunchers(I have 4, 2 completed and running, 1 needing only a pair of 275 cpus and hsf's, and the last only needing a case for the P5W+C2Q cpu). I also have two others(2-Abit AW9D-MAX motherboards), But sadly no cpus yet as I'm trying to get a 14'x60' singlewide mobilehome I bought preped for moving and moved from Las Vegas NV to Yermo CA, Then I'll have to find a place that can do setup on It(maybe the park can for a small fee).

This will be one of My newest crunchers, Sadly I'm waiting on an OS and a case. And yep It's a C2Q cpu.

Wow! You got a C2Q? Where did you score that? It would be cool to see running if you still lived in Las Vegas. Why the move to Yermo? Where is that by the way?!?!

In regards to all the talk about SSE stuff, I ran the auto-optimized seti client and it said the regular sse optimized version was the best for my e6700 core 2 duo machine. Both sse2 and sse3 tested worse.
