Its -25c outside and this is an old farm house
Ohh, I see then. Not too bad I take it?
My main experience with running multiple systems in a smallish room was my OCed dual-GPU i7 rig and my dad's dual-Prescott setup and two laptops in my bedroom. That wasn't too pleasant, especially considering it was July in NC
I estimate that it was about ~650w getting dumped into the room when it was ~33C outside
Good stuff there mjkmike
Nice stuff guys
Everything in my rig is in my room, not fun at all!
Even in winter? I'd think you'd be very grateful for it this time of year?
A lot of you guys seem to be booting dedicated WCG machines off of hard drives. Why not just use a SATA DOM or FDM instead? They're super cheap, completely silent, produce less heat, and they use like 1/25th of the power of a 3.5" hard drive.
Heck, you could even just put your OS on a USB flash drive for WCG (or Folding, SETI@Home, etc) and it would work just fine. It's not like you need very much space to hold just an OS and a distributed computing program.
Most grid / distributed computing programs aren't very write-intensive, so you wouldn't be doing much wear & tear on the flash memory either.
What exactly is a "disk on module" or "flash disk module"?
Maybe he means a flash drive?
Anyways, I use standard HDDs because I've found them to be more reliable, it's easier to install Windows to a flash drive, and I like having a decent amount of space in case I decide to use the system for storing junk as well
FDM = Flash Disk Module
DOM = Disk On Module (http://en.wikipedia.org/wiki/Disk_on_module)
I think I put those exact same definitions in my question. I did look them up. But fine, don't answer the question I actually asked and get all snarky about it. It's not like I give a shit you know.
It's still ridiculously hot in my room!
Move to Alaska CP
Here is my current crunchers:
i7 920 on the floor and 17 970 on the bench.
Lappy in the bedroom (cooler). i5 560
Wow, I would not have suspected that
How's that laptop doing? Decent PPD?
Heh, sorry. I see now that you did. It was getting late here and I was quite distracted. The definitions were more for [ION] than anyone else.
SATA DOMs are a disk drive that looks just like a USB flash drive, except it plugs directly into a SATA header. FDM's are the same thing, except using a 40 or 44-pin IDE header. I don't know why the SATA ones aren't called FDMs as well, seeing as they are both a type of FDM.
Thank you very much for the explanation. Yesterday wasn't a good one for me either. I had to deal with a couple of vendors who were too stupid to live - in my opinion.
I actually have an FDM adapter - if I haven't just made that term up. It plugged into an IDE header on one end and had a flash card slot on the other. I was going to use it as a poor-man's SSD but about the same time the prices dropped enough that I could afford a 60gig. Anyway, I knew that without write leveling (???) whatever flash card I used probably wouldn't last long.
Anyway, thanks again and WELCOME!
About 1500 ppd.
Wow...that's about what a stock-clocked Kentsfield C2Q gets. Remarkable for the size & power draw
What kind of flash card is it? CF/Compactflash? I use a lot of those at work, I have a few machines that have been running off of them essentially 24/7 for a couple of years, and are still working fine. Interesting note - the pinout that CF uses is the same as IDE (with power added - I think it's actually the exact same pinout as a 44-pin IDE, since 44pin includes power), the pins are just smaller and closer together. CF-to-IDE adapters are definitely a nifty piece of hardware to have around. I'm not sure on the proper terminology for them either... we always just call them CF-to-IDE adapters or flash card adapters.
This was over a year ago, but I think I had planned to use a PNY Optima Pro 8gig. It doesn't have a speed rating printed on it but I had used it for several months as a ready boost drive and it seemed to work fine. Lately I've been using SD cards, so maybe I'll break out the adapter and try it on one of the older m/b's that still has at least one IDE channel. Got a lot of other stuff I need to get to first though. Thanks for the info.
holy thread revival
revival indeed,,, cmon almost 5 months since last post before you,, i was thinking of making a second crunching rig from an old 2.8ghz dual core intel but it eats more electricity and provides less performance than recent hardware, giving it away to a friend in need
Thanks Don, I that looks sweet, wanna see it finished.
Wow F150_Raptor! You deserve to show that off here!
Oh yes, I agree.
