RC5 P4 Slow

Anyone running RC5 with a 1.3 P4? I just got this system and its more than half as slow as my Athlon 940.
P4 average 1.6 Kkeys/s
Athlon 3.28 { may he rest in peace}
Also I am running Win ME which I was told is memory intensive, so this could be the reason for its slowness.
Then I was told its because P4 uses the P2 Math CoProcessor.:disgust:
Thanks

With the actual DNETC client, the P4 s___s!!! 😉
There is actually no optimised client for the P4 core...
 
The Dnet client doesn't have an optomized cracking "core" written for the P4 yet. That system might do better at SETI@home, if you're interested at all. Or maybe you could trade its SETI output to one of the SETI folks and have them crack some RC5 for you, and both of you would come out ahead.

edit: Polo was quicker! 🙂
 
Try playing around with the cores at the moment to see which gives you the most speed.

Unfortunately P4 users are going to have to wait for a P4 core to take advantage of the extra possible speed.
 
actually the math co-processor in the i686 is a nice piece of equipment, the FPU in the p4 has gotten bits taken out of it relative to the ppro/2/3/celeron in order to make it run more MHz. after the dnet core starts using SSE2 instructions you chould see G4 like performance from the p4.
 
If RC5 is totally integer, than that is why it is slow.... in fact the P4 integer process thing, (i cannot remember the exact name of it) is acctually very very slow. The only reason why it performs better than a p200 is that it(integer thing) is 4x(or was it 2x i cant remember) pumped. ie: The p4 core@1.5GHz the integer thing runs @6.0GHz!(or 3 GHz) at least that is what the intel rep told me, he said it was suppose to run faster than the T-bird. Anyway that is why (in therory) it is not good for most thins at all, but least the P4 can do one thing fast: convert .wav's to .mp3! 3-10 seconds faster than a T-bird! [sarcasm]wahoo![/sarcasm]
 
OK, people dont seem to listen when this is said.

P4 has bad x87 FPU, we all know that, however its main strength lies in its SSE2 encoding. Anybody who visits Toms Hardware will have seen that using normal integer and x87 FPU functions the Athlon absolutely kicks a$$. But Intel demonstrated that when using the new SSE2 instructions the P4 is much faster than using x87 and faster than the Athlon.

This leads to the next thing people say. RC5 is integer based so there is no FPU usage, hence SSE will be of no use. Correct, but SSE2 has integer operations included as part of the extra instructions and the P4 can possibly handle 128-bit integer numbers.

We will have to see what Dnet will be able to make of Intel's new chip, but I am pretty certain that the P4 users are in line to get a faster client soon.
 
Wow, I guess I should have stated that this is my first pentium since an old 75 PackardHell, I have used AMD for most of the time after that. I had not researched the P4 at all. I was just expecting with all the P3 hype the P4 would be better than this. I will have to say that on other aspects this P4 beats my Athy. Seti for example has done 1 work unit in 7hrs 49min. Athy was in the 11 hour range. I have just got this PC as of Thursday so its capabilities are yet to be discovered by me. This is the main reason I posted this thread, I like to learn as much as possible.
I have not found many site pertaining to P4s as of yet. When asked this same question in my usual SlotA.com forum, 1 answered politly 1 laughed.
Personally I could care less whos faster, I want the most for my money.
This PC was the best I could afford. So I'd like to thank all responses good and bad, and if anyone has any links please send them on.

Amen brother.

Seti may be the game for this machine for now, but have you tried OGR yet??

/me has not seen any OGR benches for the P4. Could you turn off SETI long enough to do an OGR benchmark?

viz
 
Ok tried OGR for the day stats are 5.10 Mnodes/s is this good?
I have never really run this so I can not compare anything. 185 stat unit for 6am to 5:30 Pm
Paul
 
Thanks for the testing, Paul! 🙂 Hmm, that is not stellar. My Duron is doing about 6.35Mnode/sec at 840MHz.
 
Doesn't sound too promising on OGR either, as my CeleronII 700Mhz gets about 5.3Mnodes/sec with the newer clients...
 
Any Idea what core I should be using? It defaults to #1, but when benchmarking all OGR core it only benches #0
Paul
 
running dnetc.exe -bench will test all the cores. Someone else did this and there wasn't any improvement by using one of the other cores. AFAIK, there is only one OGR core.
 
That SETI work unit seems too slow. Are you running the screensaver client, with the graphics showing? It's bad if you are, because that slows the client down by about 50%. :Q At the least, you should set the screensaver properties to go to blank screen within 5 minutes. If you want the best performance, you should install the SETI CLI client along with SETI Driver to manage the client, and cache work units. Just post here if you need help. 🙂

Also, are you on Team AnandTech for SETI? I don't recognize your name. 😱
