Oops thanks, title changed. Even on my intel chip, I felt like the see2 app worked faster than sse3. I didn't really test sse4 since I was eager to try out emt64. When I have some time this week I might try a sse4 app too.

Please Note: Most of the work that went into the app over the default was already in place in Simon's source. I just made the modifications to get it to do a 64-bit compile.

--Bob Delkhoon (DeNitro)

Ok, It's working without any problems, Was this a Generic SSE2 originally?

On dual core AMD and Intel chips, one should compile for at least SSE3.

Intel Core2 chips have support for SSE4 in them and if you have icc and intel's MKL you should compile w/ SSE4 support.

If you are getting weird results like SSE2 being better then SSE3 or SSE3 being better than SSE4, something is wrong.
Note that to make best use of Intel's MKL may require some source changes to use functions that Intel has optimized for the Core2 architecture rather than their more generic equivalents.

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.

Also, it's =E=xtended =M=emory =64=b =T=echnology. EM64T.

With the exception of the unit that was crunched partially by Chickens app and finnished by DeNitros, which finnished with a computation error the next 4 finnihesd without error. One verified and three pending as of this time.

Times show little improvement over the 32 app. But would need to pull a unit over to comparison run with both apps.

---

Downloaded and installed on a AMD X2 3800+. Seems to be running at a few hundred Mflops faster then the SSE2 app I was running earlier, at least according to boincview. Hope this helps some.

DeNitro

I would appreciate very much the steps you took to get this client working. I've been trying for a couple months with no luck.

Maybe the Chicken can do a how to with your help.

Borg, It's an app that You were tryin to get working, not the client. Your replaceing a 32bit app with a 64bit app and the app info file is replaced too(copied over).

Oh and It works fine here, I'll have to do some detective work to find the results that It's done of course. later.

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.

Note that to make best use of Intel's MKL may require some source changes to use functions that Intel has optimized for the Core2 architecture rather than their more generic equivalents.

It seems a bit simplistic to assume that using SSE3 and SSE4 wherever possible will automatically be faster than not using it. For example, using HADDPS to sum across a register has greater latency and lower throughput than other combinations of instructions, especially on Core2 chips.

As for SSE4 (which I suppose I should be calling SSSE3 now), I think it's been discussed a couple times before--the only new instructions that could be useful for us are PSHUFB and PALIGNR, but only if we find places where using them is faster. If you can find a use for all those other SIMD integer instructions in a primarily floating-point application, all the more power to you.

I imagine the Intel compiler knows much more about choosing and scheduling these instructions than I do, but it's definitely interesting that the SSE2 app has performed so well.

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.

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

Ok I have had a few WU validate so far and none have errored out or proved invalid:

Note the earliest WU has more than one entry cause I did more than one benchmark as the Floating Point was at or near 4047(4046 and 4042 seen) and the Interger was around 8800 and I was used to seeing the Interger around 13000, But since Floating Point is what used here, It does pretty good. WU

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 ????

This is a 64bit compile of the Generic SSE2 seti app made by the Chicken, That has been recompiled into a 64bit app by Bob Delkhoon and It's making valid units and so No It should not be in Seti Beta as this is a 5.15 release, Not 5.17 or 5.18.

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.

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)

============

Oops thanks, title changed. Even on my intel chip, I felt like the see2 app worked faster than sse3. I didn't really test sse4 since I was eager to try out emt64. When I have some time this week I might try a sse4 app too.

Please Note: Most of the work that went into the app over the default was already in place in Simon's source. I just made the modifications to get it to do a 64-bit compile.

And yes I've gotten a few of the other errors, So I don't think It's totally related to being 64bit as It also happens with the 32bit SSE2 Chicken app.

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.
