This could explain a few things going on at Dnet

One Super Computer did 1.6 Million blocks in 7 days, and it was running another benchmark at the same time. Too bad they didnt leave it on, or give RC5 100%, that would have made the contest end a lot sooner, and right now, the sooner this thing is over the better.

Thanks Train!

At least someone has something bigger than Russ!

dumbredneck · Jan 4, 2001

I have my SP churning 24/7 doing rc5, alas i only have 32 CPU.

Train · Jan 4, 2001

hey dumbredneck, just curious, are you cracking for TA? or another Team, or by yourself?

dumbredneck · Jan 4, 2001

I just got hooked into the anandtech proxy a couple minutes ago, i signed up for the team yesterday. -- only had a week of work to bring with me...

dumbredneck · Jan 4, 2001

I have another big blue box (18CPU) that i got going but it is 64bit and it only does 6Kkeys/Sec using all avail CPU. Obviously it could use better core.

IsOs · Jan 4, 2001

dumbredneck

Welcome to the team!

Train · Jan 4, 2001

18 CPU's only getting 6KKeys/Sec???

Man thats pretty bad, what kind of CPU's are they? What OS? Im sure if they are any CPU made in the last 8 or so years it can do a lot better than 6KKeys/Sec.

dumbredneck · Jan 4, 2001

it is this box here ....
S80
Yeah - i'll say it should go a little faster....
it can't autodetect the CPU, so it selects allitnil and projects that it will take over a day to do 24 Work units.

I would expect 3-4M/CPU

SSP · Jan 4, 2001

Damn... Did you try using different cores?

BGod · Jan 4, 2001

Train, Only one problem with your theory. That was an article that came out last year. Check their stats for the last date they did any work and you'll see what I mean.

<< Last Block 16-Apr-2000 >>

Rank 2300 - 2399

Train · Jan 4, 2001

woops, lol, i only looked at "Dec 20th-27th" ha ha ha

Anyways, dumbredneck, have you tried KLinux on that box of yours? Im pretty sure it will recognize all the CPU's, and get a killer keyrate.

Kilowatt · Jan 4, 2001

dumbredneck,

Is your S80 box being used for anything?
Was it just sitting idle, until you tried running RC5?
Does the machine have a network card in it?

Dang it Train, you beat me to the punch!
The S80 has different processors than what is compiled into the Klinux kernel.

What OS is it running dumbredneck?
What client are you using now?

That's a lot of questions, but we'll get it figured out, and up and running.

IBM Server, priced as "starting at $420,000" :Q:Q

If you sell that sucker back to IBM, you can put together about 2,100 Duron 700's in a CrackRack from hell...

BTW, ya know what's kind of cool, IBM has a "Buy Now" button for that bad boy, it goes into your "Shopping Basket" just like buying a floppy drive from Onvia or something. I put in three just for grins, but canceled my order when I was unable to use my $400,000 off of $1,200,000 coupon for new customers.

We all are doing about 40,000,000 block's a day
SDSC's terraflop SP has been doing about 200,000 a day
That means we all together posses about 200 of those SP's of calculating power on RC5 only.

IBM needs to get something realy amasing together if they want to get close to our brutal calculation force!

dumbredneck · Jan 4, 2001

Geez KW didn't mean to get you all excited... It's running Aix 4.3.3
I don't think the guys at the office will be cool with me putting linux on it, Although maybe dual boot and do nights and weekends... it really runs at about 5% average load.

I get a decent keyrate on the 604e power PC processors in the SP, but not these. What different cores should i try?? not to be a dumb redneck, but ...

Train · Jan 4, 2001

<<

heh, ever hear of the USA Enviromental Protection Agency? Or the USA Department of Energy? both of those organizations have VERY large super computers made by IBM, both of which are in the top 10 most powerful computers in the world.

Kilowatt · Jan 4, 2001

Hmmm..Are you running the AIX dnet client?

It says it's not SMP capable, but to manually start up a client for each CPU.
I'm sure you could just use the same installation, one folder, one .exe, just use the same command you used to start the first client.
Once for each CPU.
The other dnet clients should use the same config and .log file as the first client.

In other words, do the same thing you did to start the first, only 16 times.

/me sure wishes me had one to play with. drool

ViRGE · Jan 4, 2001

After messing with my PowerBook today, I can tell you that there's definately a special core for the 604e CPUs. However, I don't know the name of it, nor if the AIX client has them. Unfortunately, I am willing to bet that because of your low scores, the odds are good that it doesn't.

ViRGE · Jan 4, 2001

Humm, I take back some of the things I said. I just checked Dnet's documentation, and I am partly wrong. The latest AIX 4.1 client(460) does indeed have the new 604e core.

Kilowatt · Jan 4, 2001

Encouragement is what we need here. Nix the negative vibes

dumbredneck · Jan 5, 2001

There is a 604e core, the 604e processors run swell, Approx 1M/Sec at 332Mhz. It also detects and spawns a cruncher for each CPU. This box has the new 64Bit IBM NON powerPC Cpus. How can i try other cores?? here is the output when it cranks up:

there should be a config menu, try running it with the option -config (not familiar with that OS though) but you should get a nice menu where you can select the cores and other congfig options.

I'm not sure what exactly the *nix command line parameters are but i think theres some thing like
Run dnetc -benchmark

and that benchmarks with all the cores, reporting the results.

here is the -benchmark output:

Hmmm... I wonder if we can get the Compaq SuperComputer project interested in competing with Big Blue's?

This could explain a few things going on at Dnet
