Let's buy GIMPS an Opteron! - Page 20

I tried to run tracegen and it just hangs. Ideas anyone?

I'm tracing an mprime built on my local Linux system.

Badly stalled. The bottleneck has been identified - we can't get data into and out of the FPU fast enough. No workaround has been found (Opteron articles suggest we should be able to do more loads and stores per clock cycle than we are seeing).

Further analysis via AMD's CodeAnalyst is difficult - it crashes my P4 and hangs when running mprime on the Opteron. I'm entering a very busy period, but it seems the next best step is to recode the assembly snipets I'm trying to benchmark in gas and build a 64-bit executable to run CodeAnalyst on.

because somebody in another message reffered to "734pin" athlon64 etc:

AMD 64bit models:

Athlon 64 3200+: 754pin, 2GHz, single channel memory, about $500
Athlon64 FX: 940pin, 2.2GHz, dual channel memory, about $700-900, identical to Opteron 14x, No SMP support.
Opteron 140/142/144/146: 940pin, 1.4ghz/1.6/1.8/2ghz, dual channel memory, about $240 for model 140 or 240 at 1.4ghz
Opteron models 240 are for dual processor systems and have SMP support.

prices are not right, they just indicate the "level" of the expenses needed to buy the cpu.

And you are right, SuSe distributions are freely downloadable. Only when you buy a SuSe distribution, you usually pay for the media, books and support.

IIRC you have to download files - they don't distribute ISOs. Depending on your Linux/unix experience this may/may not be a problem. For me, even being comfortable with some of the odder distros, I'd prefer to download something I could install from an ISO.

After having donations for funding an Opteron system and identifing the bottle neck - coding ceases.

I bet if this was an Intel processor we would have had continuous work until a fix was found.

This type of non-support for AMD is why I have turned off 12 of my 14 prime95 clients.

Actually, there are people logged into the Opteron quite a bit working on stuff... Just because it isn't posted here doesn't mean work isn't being done...

BTW, if you want an account to help let me know!

Salem,

Your attitude is unhelpful.

The machines you turned off are no doubt non-64 Athlons which wouldn't benefit from the Opteron optimization anyway. So what's the point?

Instead of conspiracy theories, let's try to come up with constructive "thinking-outside-the-box" solutions. I started a thread for this:

Salem,

Since I've been working in this opteron on Glucas, their speed has rised about a 15%. And other people is working in mprime/prime95 trying to do the things better and faster

Code:

Linux opteron 2.6.0 #2 Thu Dec 18 01:22:39 EST 2003 x86_64 unknown unknown GNU/Linux

Now the two Broadcom Gig-E ethernet ports work! We were using a crappy SMC (rtl8139) card up until now...

Well it's good

to see that work is continuing on the AMD64 client.

After the hollidays I will be configuring my dual Opteron 240 system as my main work station on Windows 2000. I am willing to help in testing.

Is there a site to download these alpha/beta AMD64 clients?

Thanks
