I'm not afraid to cheat 

Can you put your new systems 50/50 yo-yo and ZIKA please. We need a slight bump in marathon to keep us maintaining but we have a real chance at breaking forward in the city run. 

 

Everyone else just hold steady, 

 

If you are willing to put in some work setting up VMs and bunkering Einstein GPU WUs would be a great help though.

This only took a couple of hours, I am really interested to see how many I have after a couple of days. The only downside is that I switched to a 6700k for my main system, and since I lost the intel bracket for my liquid cooler, it's just pinned at 100 degrees. Now I'm no expert, but that doesn't seem to be sustainable in the long run. Anyway, I'm on it @Ben Quigley.

Ok. I did it.

I think.

...at least I own my processing power...you have to give yours back when you're done.

 

Unrelated but related and I'm posing this to everyone here what would probably crunch WU better a 16C/16T Opteron or a 8C/16T E5-2670. I could get a quad socket board for either and one sounds like it'd be a better overall idea than the other.

[Antistatic12]

Slightly late to the party but up and running on my two PC's, every bit counts.
As I don't crunch whole days, it's probably best for me to stick to OpenZika for the duration.

[Windows7ge]

@Ben Quigley So BAM has figured out I'm on the LinusTechTips_Team which means it has successfully pulled something from WCG but it still isn't showing any of my past work.

[Egg-Roll]

Just ordered the OP-SAT-1-32 from so you start (wanted it anyways) I'll set it up in the morning/after work.

Sadly can't get those extra systems running today, had a event to go to today and now I'm at home. So like 16-18 hours till they will be up which sucks.

 

Edit:

Also 6 servers will be offline for 1-3 hours in 2 days time, they'll be back up after that.

Probably the E5-2670? Would heavily depend on the WU optimization to use things like AVX, if they don't then 16 cores should edge ahead. Either case if I were looking to buy one of those used I'd get the E5-2670 because Opteron systems are very much EoL/junk now.

Do remember you need to bunker these WUs as the event only starts in 4 days.

just to clarify, i need to let these WU's run, but i won;t want to send them in untill the actual start right?

[Guest]

Ok, 38 cores going to this team.

The E5 is Sandy Bridge era so not too ancient in comparison to the Opterons. This isn't my special interest area but I don't think they're usable in quad boards.

2 socket only, the first number denoted how many sockets is supports i.e. E5-4560 = 4 sockets. Those older Opterons weren't any good compared to Sandy onward though, 16 rather weak cores vs 8 much strong so it's way to hard to say which is better generically.

 

Edit:

Unless you meant the Opteron which in that case yes it's supported, same deal first number = sockets supported.

I was talking about the Xeons, as the earlier post mentioned getting a quad board "for either".

 

BTW the 16 cores I put on yesterday are a pair of E5-2650's. Looking on ebay I could build a system with 2x E5-2680 for around £250 combining what I have and some needed bits, but outside of challenges I don't really run that system as it is a bit old.

Hey so BOINC seems to be ignoring my set memory limit, chewing it all up then crashing. Just did it again so bad I had to force power off the server. Any idea?

It's a mess of settings, did you set it on web or override in client? I believe the client override takes precedence.

I might have missed that part of it . So yea would have to look at used 4000 series xeons, used prices on quad systems generally suck compared to more standard dual though.

Client, I'll edit with settings once server has finished booting.

Argh still doing it, wtf

How are you using 256GB of ram?  

 

What tasks are running? See if you can spot the memory hogs. From memory (pun not intended), some of the yoyo tasks were memory hogs. I unselected ECM I think because of that. I had one try to use best part of 8GB, for a single unit!

 

Also see if it helps if you set a lower ram usage limit. My thinking here is that boinc might not know how much ram is in use until after tasks start, and if it starts a bunch at once it might not have time to react.

Looks like it's the ECM jobs, they spawn out at 2GB each then after a few minutes of processing bloat out to 5GB+ and nuke the server. Setting to 80% made it take much longer to die, I think I'll just keep dialing that down till it's not a problem. I raised it because if I didn't not all CPU cores would get used because tasks would be waiting for memory.

I don't know if ECM units are good credit/time but I just deselected them so I don't have this massive ram usage. I now mostly get siever units which are tens of MB each.

 

I also don't know if this work benefits from HT either. On my systems I noticed a per-CPU reported power consumption of about 85W running 75% threads, and 80W running 50% threads on E5-2650. To me it is questionable if that is doing more work, or if the power difference is simply from the HT overhead. I wouldn't worry about it as long as over 50% threads are in use at a given time, as at least every core has work to do.

I might have to do that, any way to limit the number of ECM tasks or can only turn them off?

Turn them off. Link should take you to your account settings page when logged in.
