AMD 64 for PSP

em99010pepe · 2004-09-28, 21:23

Fargot to tell my PC has an AMD 64 3000+.

Just trying this project to see how fast my AMD is.

Is PSP optimized for AMD 64 processors?

Hi,

The prime finding software isn't optimised for particular processors in general, BUT some procesors are way better at sieving or PRP'ing than others. The AMD64, you will be pleased to know is great at sieving and PRP'ing.

Just for info Athlon XP's and P3's are great at sieving and P4's are better at PRP'ing.

Good luck.

Thanks all for the welcome.
I tested the PSP client in one P4 2,8Ghz, one AMD 1100Mhz and one AMD 64 3000+.

Results:

P4 2,8Ghz------------>Time per bite: 6 ms
AMD 64 3000+-------->Time per bite: 11 ms
AMD 1100 Mhz-------->Time per bite: 26 ms

Shouldn't be better the AMD 64? Or client just need pure clock speed?

Carlos, AMD 64 shouldnt be that bad, are you using the right XP version on the computer? IT should have the same speed as the p4 2.8 GHz.

That is what I have learned from my experience. I do not personally have a computer with an AMD 64 processor. All my computers are p4's.

First I'm sorry for writing those questions in the Teams : Join a Team thread.

Second I have installed WIN XP SP1 because Win XP 64 Bit edition is still beta version.

I don't know If I'm using the right client but I downloaded the Automated Network Client from this page:

You are using the right software, but you are not using the right XP version. Unless you change to the 64 bit version, you will not be able to harness the real power of an AMD 64. I personally recommend that you contribute to the sieving portion of the project with you AMD 64 and use netowrk client for the rest of your computers.

As for posting on the Teams thread, it was no problem at all. I can move posts around, so not a big deal.

On second thought, changing to the sieve will also not help either as the winXP will assume you have a 32 bit processor and work accordingly, making the 64 bit ability of AMD of no use.

How I do that? Do I have to install another client?

So no luck.
I'm going to leave as it is.

As there is no 64 bit version of either PRP or proth_sieve available, the 64 bit extensions won't increase performance even on 64 bit capable OSes.

The Athlon64 has the SSE2 extensions, which definitely support calculations. Thus, the per-clock performance is near that of a Pentium4. Sadly, George was unable to improve performance for the Athlon64/Opteron architecture in particular.
AFIAK, they don't get the whole cache throughput somehow, but George couldn't figure out why.

So for PRPing, P4s are better than AMD64 CPUs. Sieving however is a completely different story. There, the Athlon64 clearly flexes its muscles.

I'm having problems with sieving software.
After adding the range the DOS window just vanishes.
