Probably a good idea, but I don't. Linux in particular there's no reason to install AV software; Windows its debatable. But I don't have AV on my laptop anyways (it's old and slow) and I figure that if the laptop can do without, so can the systems that have only BOINC and are never touched.

imo, if it's behind a router/firewall and all it's doing is crunching, it'd only be vulnerable to some kind of man-in-the-middle attack or from another PC on the network. I don't think it's worth running AV, certainly not anything realtime.

Worse case scenario, something malicious gets on it and you have to wipe/reinstall. If it's a dedicated cruncher, that shouldn't be too big of a deal.

I want to get a cheap WiFi adapter for one of my pcs, and I found one of these for $10 for sale on [H]. Any feedback on it? Newegg reviews seem decent enough, and it's pretty much a dedicated Cruncher, rarely gets any other use.

I'd probably spend the extra $5 so when it inevitably fails you can get another one easily via warranty. If I know one thing about USB WiFi adapters on crunchers it's that they love to fail (especially now that it's going to be warming up).

Exactly. Given that it's never touched (except for HW failures or whatnot), updates are automatic, and it's behind a Cisco "enterprise" router (purchased from someone b/c the "firmware was too complicated") I don't see how they're at risk of much of anything.

It should work well for me then. The range I need is only about 6 feet (direct) and no walls between. Just hate the idea of constant drop of connection. I think I'll go for it

Mine works just fine at a range of ~15ft with a couple of walls in the way, so you ought to be OK
Is Ethernet not an option?

 

[Toothless]

Someone said ethernet?

Eeeahh. Wireless infrastructure to crunching machines seems cheaper than wired infrastructure. $20 for a tiny switch, $5 a cable, need more switches the more machines you have, cables get messy, etc..
Wireless, just set up an AP (or one machine with a bridged wifi adapter in ad-hoc mode). Should be able to pick up cheap used ones (a lot off fleabay maybe?). Easy.

'suppose I'm spoiled by my cheap parts. $10 for a 16 port switch and any-length ethernet cables for $1 makes wired a very cheap choice (albeit messy).

There was a recycler nearby, but they went under (and usually didn't get anything good). I miss my cheap parts!

Ethernet is an option and is employed currently. Thing is, the cable stretches across the floor, and with little kids always playing, things fall, already has lol. Plus it doesn't look that pretty, for the wife.

Understood, that would tend to be an issue. I suppose it's nice that I have a roomate my age who won't mess with stuff and who doesn't care

Wifi sounds like a much safer plan.

Thanks, was looking for this kind of info. I've never used a USB adapter and was unsure of their longevity.

Indeed so, appreciate the affable circumstance you enjoy now; it may not always be so easy going I'm not complaining though

Boy, picking a PSU is the biggest pain. I'm looking for the cheaper side, so about $80, and there is nothing really there. A 600w (50w more than now) is actually only $70, but then the 750w (What I wanted) is $90, and then the 850w gold with enough connectors for 3 GPUs is "only" $99 for the rest of today only. Not worth buying the 850, the 750 is disappointing since it was just $84, but I might go for the 600w. OTOH I will probably have to wait 3-6 weeks for Gigabyte to RMA my GPU anyway.

I'll probably end up waiting for a sale.

Well that is not entirely true. The CEP units have very long time between check points. You could lose 2-3 hours one these. The rest is only a matter of minutes.

OK, if you REALLY want to hone the toothpicks!! Why don't we go into a long and boring and confusing conversation about CEP Checkpoints. I'm pretty sure that will make the original post-er feel more at ease with the whole re-booting situation.

Sorry, my butt hurts.

 

[Nordic]

How come?

Because I am moving.

I am down to about 60% folding capacity now. Still have 6 cores to turn off. Nice thing is half my folding force is remote so no matter what I will have ppd. I am trying to leave them on as long as possible as I pack.

Speak of the devil (or networking, as the case may be) but the 16 port switch that runs a bunch of my crunchers seems to have died. I'll buy a new one later this week, but in the mean time there will be a LOT of ethernet cable switching :/

Alright, finally get a little bit of a chance to diagnose my HP Z600 with a Xeon X5570. Kept shutting itself off. Crunching in the office, it's hitting 81c on all cores in about 10 minutes of crunching (which just happens to be the thermal shutoff for these procs). Fan speed isn't ramping up at all, for some odd reason. Can change the "idle fan speed" in the BIOS to one of five or six different levels, sticking it second highest keeps CPU temps around 70c now.

Interestingly enough, changing the "idle fan speed" only changes the tach for the chassis fan sensor. Sure enough, CPU fan speed doesn't actually change. Just changes the two fans in the back and the one in front. No idea why it wouldn't ramp up the CPU fan (which sits at about 800-900 RPM). PWM signaling issue? Seems like failure would have it sit at 100%. Might try disconnecting PWM to see if it ramps up then. Halp?

Had one of mine half give out a little earlier (little gig switch wouldn't do more than 3-4Mbps in one direction on a gig link, did that on any port, but only to one computer). Maybe it's switch dyin' season.

On an unrelated note, this Intel Compute Stick looks interesting and it's set for pre-orders! Get one with Linux for even cheaper (MSRP $89, so I hear.)

The Split X2 lives i3 3229Y 2c/4t is happily crunchinng at 50% load temps are no more then 70C either. Not to bad for an ultrabook

That's odd. I'll check on my Z400s after class this evening, but I'm pretty sure that the fan speed ramps up as might make sense. And given that two of them are stuffed into a small cabinet, they get pretty hot....upper 70s at load.

Beta Test - Uncovering Genome Mysteries - v7.28 - Apr 7, 2015
We are conductiong a beta test for Uncovering Genome Mysteries on both Linux and Windows. This update includes I/O changes which should improve performance.

Thanks,

Get them while they're hot, I've managed about 85 of them

 

[Arjai]

I finally get some BETA's, 4 of them, and they are running under Kreij's account, not mine!! I may never get a Beta badge!!

As long as my SSD doesn't crash, WCG will be running at least 10-12 hours a day while I'm at work or asleep. Sadly even less when I'm on my days off though if only I had an extra rig then I could dedicate. That's for when I pay my own bills.

Sometimes it feels as though I have the WCG Forum, all to myself!!

They don't thermal throttle either, which is annoying. Watching lm-sensors in Xubuntu, I unplugged the CPU fan and none of the tach readings dropped. It's actually not even monitoring CPU fan speed (not in the BIOS either, iirc). Might see if there are any BIOS updates.

I have a few random AIOs and a LOT of zipties. I'll make something work if I have to.

I checked on the Z400s I have and the CPU fans certainly seem to increase speed as temperatures go up. Neither of the CPUs do the full turbo that they ought to do (which is odd, as the X5672s in Bucharest do, and at higher temperatures), but they still turbo a tad.

Tonight's catch: a Dell T5500 workstation with a pair of E5620s for $20. No RAM or HDDs, but the case, an 850W 80+ Silver PSU, motherboard, heatsinks, plastic bits, etc. Wiki says they have a full-load turbo speed of 2.53GHz, so I suspect that this system will do somewhere in the PPD range of a decently OC'ed Sandy i7 for about 12% of the cost (I have spare RAM and nearly a dozen of the old WD Raptor drives).

Damn I'm jealous, never see anything that cheap around here, people want top dollar always.
