RE: Hey, my extra 1GB

Message 69864 in response to message 69859

Hey, my extra 1GB memory finally arrived and now my two dual PIII-S boxes have 1 GB each. I took the opportunity to measure the power consumption, and it's around 135 W (for one server Dual PIII-S 1.4 GHz, 1GB RAM, 1x 36 GB HD, onboard graphics) .

They yield about 420 credits / day, or 17.5 credits /h , so they need about 7.34 watthour per credit. I think that's not tooo bad in the server/desktop league.

My Mac Mini needs about 1.2 Watthour/credit, but it's build from notebook components so it's playing in a different league.

i have found that pentium 3 and 4 systems make great crunchers. i'm building an increasingly larger pile of older systems that do nothing but crunch.

it has been interesting finding out how to optimize a linux install so it best utilizes the [somewhat] limited resources available. i hope to start bringing on line a handful more p3s and possibly some SMP p3 systems.

RE: Memory was delivered

Memory was delivered today for the 440, works great, no fault lights or errors, to bad the OS hangs. :( Tried with HT on and with it off, same thing both ways. Wondering if it makes a difference that only the one SMP module was enabled when the OS was originally installed? Think I'll run it dry and try a re-install on the OS in a couple of days. It's either that or find one of the 12.7mm slim DVD drives and load Server 2008.

I was looking forward to running all 8 cpu's with HT on, just to see how it would do! :(


Have you tried a Linux Live CD boot?

Anyway, the 440 seems to be very special bcause unlike other Intel SMP boxes (but similar to AMD multiprocessor solutions), it has a NUMA design as the physical RAM seems to be split among the SMP modules. That requires same extra "Hardware Abstraction Layer" drivers for Windows, maybe you need to reinstall those drivers with the second module installed.

Decided that it would be

Decided that it would be easier to install the OS on another drive, rather than mess with the one in there now and run the chance of aborting WU's that are running.

After several tries it works fine. Works best installing the HAL supplied from IBM when installing the OS. Since the OS is now installed on 3 drives I can go back and try a "repair" on one of them and see if that will work for installing the HAL to an existing OS, without wasting any WU's.

The 440's are a little different. Each module has it's own VRM's, cpu's, L4 cache, and memory (four 512's min memory install per module). The modules are connected to a center plane and secured with two locking lugs and a support bracket. They are also connected together with 2 external cables. Those external cables can be a real pain. For anyone that might run one of these I'd suggest that you remove the rear EMC shield, and leave it out, before installing the SMP cables. Turns out that the slots where the cables mount is not quite tall enough, you can install the cable, but it is a REAL PAIN to remove them! Takes about 2 minutes, after removing the cables, to remove each module if you need to work on them.

I haven't used a live CD on it yet. Have several, if I could remember which ones are the "Live" ones. Naturally, it would have been to simple to write "Live" on them at the time!

Checking in Device Manager

Checking in Device Manager this evening and found that the custom HAL from IBM had been overwritten someplace along the line. Reinstalled the HAL, shut down, installed the memory, connected the cables for the second SMP module, started it up, and, it works! No fault lights, no beep codes, just ran through POST and booted the OS, no problem. I happy now! (Simple things for simple minds) :)

yaaaay I will be adding

yaaaay

I will be adding the following systems to the crunch farm in the next few weeks:

Two p3 500 Gateways, one Dell SMP P3 800, one Dell SMP p3 666, and since I have an extra harddrive from one of the SMP systems I'll be able to re-add one of the p3 450s back into the mix.

I'm waiting on two more SMP P3 Gateways, as well.

As soon as I have time, I'll format the last of my systems running Ubuntu and put on Fedora so I have more control over what runs on the systems.

Plus I scored a 24 port 10/100 3com switch off ebay for 27.50 including shipping. I hope it isn't a dud because my hodgepodge of crappy 10mb hubs and just-as-crappy 4 port linksys routers is irritating the hell out of me. Plus all this junk eats up valuable power outlets.

I didn't see any Rise CPU

I didn't see any Rise CPU systems in the statistics, so I tried to set up one.

That should be interesting. . .

About a year ago, I managed to do one of the 12-Cobblestone S5R2 work units with an old 200 Meghertz Cyrix 6x86 machine, running Windows 98. It took something like 112 hours. (The same size work unit would take about 40 minutes on my 3500+ machine, which was the fastest machine that I had at that time.)

I think it was very

I think it was very optimistic of the scheduler to throw 5 WU on this little CPU :-).

On paper it looks far slower than the OLTC discussed in the "Getting Started" section.

Here's a review of the thing..

It's not SSE capable, is it?

The scheduler calculated 37 hours / WU.
I think, it will be a bit less than 300... :-)

It knows only x86, x87 and MMX instructions.

That's better than my Cyrix, at least. It doesn't know MMX.
