I've been crunching since 2001 and only use the stock Seti. I have been reading a lot about the optimized versions for AP and MB.

Here is the system I have and I would like to know what you recommend I run and how if possible. I am not computer illiterate just haven't really tried anything other versions. I am looking to increase the production of work units since my PC is idle for most of the day.

This is what I would recomend http://lunatics.kwsn.net/gpu-crunching/v9-of-modified-seti-mb-cuda-opt-ap-package-for-full-gpucpu-utilization.0.html

You should run CPUZ to be sure but I believe you want the one for AMD and SSE3.

Note: You have to register on their site to download but it is a very good site and a great bunch of people.

AMD Athlon(tm) ... sse2

They're the important bits.
You've an AMD CPU that only has SSE2 capability (there's been about 2 or 3 upgrades since then). So you need an application suitable for that CPU.


[url]http://lunatics.kwsn.net/]Lunatics[[/url Have the optimised applications for download.
There are links to packages (Astopulse & Multibeam applications that also include the app_info.xml file required to get BOINC to use the optimised applications).
However there has recently been an update to the AP application & the updated application hasn't been put into those pakages, so you'll need to download the latest AP application & modify the app_imfo.xml file accordinly.

I'd run CPUz to check, but the log posted shows only upto SSE2 capability.

Ok. I ran it. In the instructions is shows SSE2 and SSE3 instructions. So I should be good.

I would also make sure that in your Computing Preference Settings you have "Suspend work while computer is in use" to "No". "On Multiprocessors use at most" set to 4. "On multiprocessors, use at most" set to "100 % of the processors". "Use at most" set to "100 percent of CPU time"

Grant, mine also only shows up to sse2 but CPUZ shows I have ssse3. Most of the newer AMDs have sse3 and that is why I recommended that one. That is also why I said he should run CPUZ to be sure. http://www.cpuid.com/cpuz.php

Ah, i'd forgotten about those. That was a long time ago (as these things go).
Go SSE3 as others advised.

Yep, getting forgetfull in my old age. I hate it when different companies give the same things different names.

I recall all newer AMD x64 Processors by default do use SSE3

Never trust the processor features that BOINC reports. BOINC asks the OS what features the CPU has, and therefore will only report what the OS will look for. The same hardware on Windows versus Linux will show drastically different processor features.

On my Athlon64 3000+ (Winchester core), Windows will only show "fpu tsc pae nx sse sse2", but Linux on the same hardware will show "fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni"

Hm.. I didn't think this processor had sse3 (pni)..but I guess it does. I guess I could try running the sse3 opti apps and see if it likes it. I've been doing the plain SSE ones.

All amd 64 bit CPUs are SSE3 by default. So you shouldnt have any problems with running an Opt app running SSE3

Wrong...again. All AMD 64 bit cpus have at least SSE2.

I thought SSE3 started with Venice, so a Winchester should be SSE2.

This is correct. Not all AMD Athlon 64 CPUs have SSE3. It is completely dependent on which processor revision/core in use.

Interesting.. The winchester at work has 'pni' when I do "cat /proc/cpuinfo", but doesn't say anywhere about sse3 (I'm guessing that's what the industry decided..is that we're not going to call it sse3, but pni instead..), and my Sempron(64?) 3400+ says the same thing.

Before I knew about pni being sse3, I did a bunch of google searching trying to find the supported instruction sets for that sempron3400 and kept seeing sse2 everywhere, but nobody said anything about SSE3.. then I remembered. Three years ago when I was building a budget rig for work (which I ended up taking back when the boss man decided not to give me my last paycheck), I took a screenshot with cpu-z after running through superpi 32M, and sure enough.. SSE3.

Notice I said "Sempron(64)" in that way. The box doesn't say Sempron64, and neither does CPU-Z, but it was mentioned previously on the forum here that I implied that it wasn't the 64-bit variety of the semprons since I didn't append the name with "64". Just making that a point. :p Don't blame me, blame AMD.

The Clawhammer, NewCastle and Winchester only support SSE2. Venice, Orleans, Manchester, Lima, San Diego all support SSE3. Or, saying it another way, all E3 revision CPUs including Sempron chips and later support SSE3.

I can't tell you why it reports that way other than perhaps you are mistaken on the core name on the CPU chip at work, or perhaps pni has a different meaning under AMD CPUs (I know that AMD's implementation of SSE3 isn't complete as they left out 2 instructions specific to HyperThreading which AMD CPUs do not support), or it is being incorrectly detected by Linux. The Palermo Sempron is an E3 rev CPU so yes, it has SSE3.

unfortunately it's a linux-only server, so I can't pull up cpu-z to see what the verdict is. I remember taking the CPU out of the box, and I'm pretty sure it said it was a winchester. I looked to see if there was something cpu-z-esque for Linux, and in a general sense..no.
