8th Annual BOINC Pentathlon

[TennesseeTony]

Whew. We held onto 9th place at the end of the Cross Country, Einstein.

HUGE Congrats to our friends at OCN for kicking butt and taking 1st!!!

Looks as though P3D and China had some decent bunkers, but it didn't change their standings.

Congrats TeAm AnandTech! 9th is the highest placement I've seen for our team in recent Pentathons!

Here's a snippet from last years medals ceremony:

13. TeAm AnandTech (14-14-17-17-13) – Previous year: 18th Place
Even at TAAT, the best Pentathlon-result has been recorded. On equal points with Crunching@EVGA, in the end the better individual rankings made the difference. That’s where their end offensive at the Marathon really paid off.

hardocp have added some in cosmology yesterday.

 

[iwajabitw]

Congrats everyone! So it would seem our small little band, will gain some attention from the Empire this year.

 

[TennesseeTony]

Yeah, biggest reason I'm trying to optimize my VM's again.

 

[iwajabitw]

With the only GPU project going, Moo, I have 2 system there. 3 systems still on LHC.

 

[StefanR5R]

That company produced 88 % of hardocp's points at PrimeGrid Newton challenge.

 

[TennesseeTony]

Holy Smokes, I just saw the previous link. That's......a lot of horsepower. Surely when business hours resume that will disappear, but until then...

 

[TennesseeTony]

Nooooooo! I just heard a loud pop from the adjoining room, followed by near silence. I walk in to find Skeletor, ThunderStrike, and two lessor systems, lying on the bench, lifeless.

The breaker tripped on a 20amp powerstrip. Uhm...sugar. That's a lot of juice.

Hrrrmmmm. Maybe I can squeeze one of the lessor systems onto the UPS setup...it has 432w to spare....only adding 300w at most. I think.

 

[iwajabitw]

@tennesseTony, grab a 12 guage extension cord and run it from the fridge or the washing machine outlet, those are wired 20amps in every home.

 

[crashtech]

So we need a house wiring modification thread!

Yeah, I do it all the time, 15amp GFI's tripping cause the lady plugged in here 1800w hair dryer. Watts/volts=amps or amps x volts=watts.

 

[TennesseeTony]

It's a 12ga circuit with 20amp main breaker. I'm glad it tripped the buit-in 20A at the power strip first. I hate going outside and fumbling with the breaker panel at midnight. Got her down to 19.3 amps now. Just have to be careful not to turn on the light unless I really need to.

P=IV
Power(watts)= Volts x (I)current
Simple algebra lets you switch that up if you like.
I=V/P
V=P/I

Quite useful when running 15 computers and 11 GPU's on 2 circuits. Until the power draw changes on you.

LMAO, I so thought, I was done with Algebra, until I got into HVAC and sizing duct work, FPS to CFM and all that plus electrical. Guys question the hell out of any contractor you ever hire, since we are tech guys, always do the math.

 

[ocukguest]

were lucky over here in the uk having our full house wired as a ring main rather than loads of random radial circuits. 230/240v with a 32A breaker as standard. depending on house size kitchen on 1 ring and the rest of the house on another. or some bigger houses up and down may have its own ring aswell.

 

[StefanR5R]

So there is this one occasion where I, the n00b, was in a position to give you guys some info on a project, and a GPU project at that. And promptly I fail to mention one of the most notable aspects of the project's GPU application: That it draws power pretty good.* Especially notable since we just did Einstein with its more moderate power consumption.

You found this out quickly by yourself, but an advance notice couldn't have hurt...

------------
*) Reasons for this oversight, besides my n00bility, was that I had been running Moo mostly on the AMD W7000 previously, which is lower power than similar consumer cards. (Additionally, mine is virtually noiseless because modded with a triple-slot air cooler.) And the bigger consumer cards which I got myself lately do not give out any alarm sounds during high power draw either, because they are also equipped with big-ass triple-slot cooler or are sitting under water, coupled with reasonably large radiators.

I did notice that my GTX 1080 operates at the board power limit when subjected to Moo. Next time, if there ever is one, I try to remember to mention such things prominently. I even increased the power target for this sprint, so that it is limited by voltage now. An air cooled system might become limited by temperature, depending case ventilation and card fan profile of course.

When stationed in Italy, the entire 3 story office building of the compound was on such a circuit, a single 200amp. Above my typewriter was an OLD outlet, with wires hanging out. Disconnected, surely? Hmmm. I fed a paper clip through the eraser of a pencil and touched the leads. Poof. The entire building went dark.

I was not popular that day. "Ur, uhm, just investigating a safety concern, sir."

 

[StefanR5R]

Sadly, my i7-6950X PC with 3 GPUs switched itself off an hour ago. At power-on, the mainboard's CPU LED stood lit.

Haven't seen or smelled any magic smoke escaping, and temperature sensors always showed good values. When I removed the waterblock, TIM imprint on the 6950X looked reasonable too.

I swapped in a spare E5-2620v3 now, so that I can at least continue these last hours of the Formula sprint. This little buddy has even more difficulties to keep the GPUs fed; I switched from 3 to 4 feeder tasks but still have a bit less GPU utilization than before.

 

[TennesseeTony]

Oh no. I've lost several AMD's in years past, but never an Intel. Sorry buddy.

 

[crashtech]

@StefanR5R ,Wow, that a rare and distressing event. My condolences. Any hypotheses as to why this happened while leaving the motherboard undamaged? Most often it's the other way around.

 

[crashtech]

LHC persists in sending work other than sixtrack in defiance of the settings. I must manually abort these to prevent problems.

In March/April, between the Yoyo and Einstein Formula sprints, I added two GPU waterblocks and another radiator to the waterloop. After I had refilled the loop, bled the air, and leak-tested it on cold components, I had it running for a short while, but then the pump broke down for whatever reason. There could have been a few minutes maybe during which the CPU ran at full power without water circulating. Maybe that left some damage. Though since when I replaced the pump, the CPU had been running without apparent problem.

LHC persists in sending work other than sixtrack in defiance of the settings. I must manually abort these to prevent problems.

Check that "If no work for selected applications is available, accept work from other applications?" is a "no", and that there aren't separate preferences for "home/ school/ work" applied to the affected machine.

Intel CPUs are supposed to thermal throttle tomorrow prevent damage, but it may be that this is not always enough to prevent localized hot spots from eventually causing damage. A caution for us all, but to have it happen on such an expensive CPU is a tragedy to us techies.

Check that "If no work for selected applications is available, accept work from other applications?" is a "no", and that there aren't separate preferences for "home/ school/ work" applied to the affected machine.

Yeah, that's the odd thing, I double checked that then updated the project, and still wrong work comes, but only on certain machines. Others are unaffected. It may correlate with the presence of VBox on the system, I'll have to check.

Edit: I believe that in my case, the presence of VBox on a given PC was affecting the kind of work LHC was handing out. Once uninstalled, these machines no longer receive anything but sixtrack, where they had been receiving other things like Atlas before, regardless of the settings made to my profile. Strange.

 

[TennesseeTony]

And you don't have separate preferences for "home" "work" or "school" I'm sure, so that is weird indeed.

Off topic but we're looking good for 2nd in the FB Moo! race, and third across all 3 leagues.

That's interesting. I set mine to allow other tasks if they're out of what I select, but it refuses to. Maybe try that setting?

 

[StefanR5R]

At least for me, the "If no work for selected applications is available, accept work from other applications?" = "no" setting works as intended so far, on a Windows machine which has vbox installed and working for boinc applications.
