I'm joining TA ECCp-109!! :) Help needed!

Gdays people!

Note to the SETI TeAm: My herd is not going away from SETI 😛

I'm doing a little experimenting with ECCp on my home computers! So far, I've been running ECCp on my 1.2GHz Athlon4 Laptop, and I've returned 3 results in the last half hour or so. This is WITH SETI running as well!!! I've noticed that my peak output on ECCp is about half its max with SETI running, but my SETI output has been virtually unaffected (I'm guessing my average times from this machine may rise from 6:30 to about 6:50 with ECCp running.)

Can any of the ECCp gurus tell me how fast ECCp should be running, and what is its speed dependent on?

How fast are P3's, P4s, Celerons and AthlonXPs at this project?

Finally, what output would my SETI herd give in ECCp? (I output about 220WUs/day in SETI). Not that I'm going to transfer away from SETI, just that if this experiment works, I may have some of my herd doing both SETI and ECCp.

P.S. To my SETI TeAmmates, sorry bout the thread title 😉 Had to get as many ppl in here as possible!! 😛

PieDerro,

I will answer your questions as best as I know how. I am not an ECCp expert so if someone comes along like MereMortal or Nagger they will probably be able to give you a better answer.

From what I can tell, ECCp is is not as dependent on FSB as is Seti. It seems like it is really all about the processor.

The Athlon XPs are by far and away the fastest processors in this project. P4s are actually not good at this project while P3s do fairly well for their speed.

If you could give some more details by processor type etc, we could probably take a shot at figuring out how many DPs per day you could produce.

Your Seti WU CPU times won't change, but you'll get 1/2 as many done as ECCp and Seti are at the same priority level, so CPU is split 50/50.

The fastest clients are the Statsaholic clients. There are optimised clients for PPro P2 and P3, Pentium, and Athlon CPUs.

For reference, my Athlon @1.33GHz (133x10) i get just under 1 million iterations/second (~880k-950k). My Celeron 400 (in SMP - one CPU) gets about 130k per second.

Welcome to the ECCp TeAm 😀

Oh yeah, 1 DP is about 50 minutes work on a P2-400 🙂

DOH! Look here too!

PieDerro,,

I had SETI and ECCp running on my XP 1700+ for a few days. I don't remember the output for ECCp but I do remember this: My Times for Seti appeared to stay the same but in reality they doubled. The cpu times were almost identical but they were only using 1/2 the cpu time available so in reality they were longer than normal. I hope this is not confusing. It is almost like running two instances of seti.

Thanks for scaring me like that! :Q 😉 I think you should run ECCp during our race to 10K! 😛 😉

As others have mentioned, you don't get someting for nothing. Your SETI times may appear to be unchanged, but your output is really halved. ECCp is is less reliant upon memory and other subsystems than SETI.


The relative speed of CPU's in ECCp is as follows (from fastest to slowest):
Athlon XP/MP/Tbird/Duron...600 it/s/MHz
Athlon Classic......................587 it/s/MHz
PPro/P2/P3/Celeron............445 it/s/MHz
K6-3....................................336 it/s/MHz
K6-2....................................317 it/s/MHz
Pentium MMX......................240 it/s/MHz
P4.......................................227 it/s/MHz
Pentium Classic..................200 it/s/MHz


These numbers are a little old but they give the relative scalings (up to 12% too slow). The often used benchmark is that for an Athlon, you get 100 DP/GHz/day (it's really like 108, but it gives you a good idea).


The fastest clients are actually not the statsaholic clients. Because of the features that the statsaholic clients offer, they are slightly slower than Ken_g6's clients.

What, I have to do everything? 😉🙂

Ken_g6's windows GUI client
Ken_g6's windows CLI client
My linux clients based on the CLI above

Note that these windows clients need the cygwin1.dll, and they start with normal priority. You can get the dll file from the statsaholic distributions, or www.cygwin.com. You may wish to lower the priority to the low setting if you plan on doing anything else on the PC.
