Can i make my AuthenticAMD AMD Athlon(tm) XP 2800+ faster? curently runs at 2.08Ghz,It dose 4 WUs a day.

Do you mean by "over-clocking" or just getting more WUs per day at the 2.08GHz speed?

Just getting more WUs per day at the 2.08GHz speed.

Yeah, do a search on the forums for optimized clients. There's plenty of info.

Hey guys, which do you think is better at crunching numbers in BOINC? Assume both chips have identical speeds.

Forget AMD and Intel
I'd like to see how a transmeta processor does.

SPARC, DEC Alpha, HP PA/RISC... I'd love to see stats on all of those. You can actually buy an Alpha or PA/RISC workstation right now for very little $$, although it'd be an older one... no clue on SPARCs, never followed Sun.

I seem to remember an incredibly fast apple chip in the past that didn't even need a fan because it ran so cool. I may be mistaken though.

[font='courier,courier new']I think you're referring to Exponential Technologies's chip: A bipolar CMOS PowerPC that ran a wicked-fast 533MHz when typical speeds of the time were around 110MHz.

It was such a good chip that something had to be bad about it, and that was the amount of heat it generated. You could boil water with it.[/font]

No doubt about it, the AMD64 X2's are the current cream of the crop - they are significantly the fastest processors and operate at far lower power producing far less heat. If you can afford one this is definately the way to go :)

Ned, are you including the G3,G4,G5 apple processors when you make this statement. Or, are you only including AMD, Intel proccessors? I seem to remember an incredibly fast apple chip in the past that didn't even need a fan because it ran so cool. I may be mistaken though.

I was only considering AMD/Intel as per the thread title. I'm not aware of any Apple based machine that can compete with an Athlon64 X2 on seti performance.

The closest I've read about is the transmeta chips. They can run without fans due to throtling and power managment software. As I understand it they've licensed dual core technology from amd. Their next generation of processors should be pretty interesting.

Just getting more WUs per day at the 2.08GHz speed.

If you have adequate RAM and have CPU cycles for BOINC, I think you won't get much additional production unless you use an optimized application.

I have a SPARC box on my computer list, but for some reason it's results have disappeared ...

Anyway, CPU/System spec:

UltraSPARC IV 1.05Ghz dual core, 16MB L2 cache, 64-bit V9+VIS instruction set
SunFire V490 server; 4 x US IV CPUs/32GB ECC registered DRAM/2 x 73GB FCAL HDDs

Running Solaris 10 x86-64 GA and BOINC 4.19 with a standard SPARC SETI client we were seeing runtimes of approx 8 hours per WU per CPU.
So for 1 UltraSPARC IV you'd expect 2 WUs every 8 hours (the design of the US IVs has 2 physical cores within each CPU rather than 2 virtual cores, i.e. HyperThreading) as the performance increase is effectively linear as the number of cores/CPUs increases.
So with 7 of the 8 cores crunching simultaneously we were seeing 7 WUs completed approx every 8 hours.


As far as buying a SPARC machine ...
The SunFire v490 on my list has a list price of ~$60,000 ...

The cheapest SPARC new workstation Sun currently sells (without including the low, low end, soon to EOL UltraSPARC II SB150) is the SunBlade 1500 with a 1.5Ghz UltraSPARC III-i CPU ( http://www.sun.com/desktop/workstation/sunblade1500/ ). Prices start at ~$3,100.

Although there are always Sun workstations kicking around on eBay, etc.

That's not much better than my old home built dual 700MHz P3. When it was running the unoptimized client on xp it averaged 2 work units every 10 hours. Sure your sun computer finishes them 20% faster but for that price I'd expect more of a difference than that.

Bear in mind SPARC doesn't have the instruction extensions like MMX, SSE, 3DNow!, etc that Intel and AMD use. I'm not sure how much use the SETI clients make of the SPARC V9 +VIS instruction extensions.
I was planning to recompile the SPARC/Solaris client I have using Sun's performance libraries but I haven't got around to it yet.

Also, you aren't paying for raw CPU performance with one of these boxes, you are paying for capacity to do work, warranty and service, a box that probably won't need to be rebooted for years on end, huge RAM capacity, massive memory and I/O bandwidth, hot swap everything, everything from chip and board design up to OS and application layer integrated by one company, massively scalable architecture with almost linear performance increases (the performance of a 106 CPU UltraSPARC server running Solaris (and a highly threaded application) is over 100 times the performance of a 1 CPU UltraSPARC server running the same OS and apps) - you don't get that on x86/Windows.


It's a well known fact that SPARC hasn't been top of the CPU tables for a while when it comes to single thread processing power.
But the entire architecture (CPU RAM IO and everything in between) is still regarded as one of the best around.

And just wait for Niagra ...

if you don't have to reboot every week, aren't you afraid of forgetting how? Wouldn't you be embarrassed to pay for a tech support call to ask?

Sorry, AMD is the best!

It gets worse that that!

I've forgotton what the "/sbin/halt" command was for one server after it had been left in a dark corner of the server room for over a year happily doing its stuff untouched. Took a few guesses just to hack into my own box!

And then, from a real incident:

"How do you power off this machine?"
- Linus Torvalds, when upgrading linux.cs.helsinki.fi, and after using the machine for several months

It's just one of those things that you don't need to do very often, shrug.

Another real experience: a couple of months ago I tried to compile BINC and SETI binaries for Linux/Alpha. I was just too optimistic about that so I first killed off my SETI/classic client ... until then that single process crunched 533 CPU days. The host's uptime is nowadays nearer to 650 days. The rest of CPU time was spent for weather forecast model.

No fancy hardware there: an off-the-shelf alpha SX164 with PATA disk and two tulip NICs ... acting as a master of 5-node cluster (slave clusters boot off this beast).

Metod ...

[font='courier,courier new']I'm reminded of a story I was told about a Novell server that was slated for being replaced. The IT dept. tried in vain for a few days to track down where the damn thing was. Ultimately, they had to start picking up the floor and start chasing cables, just to locate WTF this box was. As they were tracking the cables, one fellow found a set cables led to a wall, but didn't come out the other side.

After some head scratching, he came to the only conclusion possible: The server had been walled in. Sure enough, there the server was - Untouched by human hands for four years.

Granted, this might be one of those urban legends, but when the creator of Linux can't figure out how to shut down... it just might be true.[/font]
