World CEP2 Challenge (6 october - 14 october)

[Arjai]

We have 18 Teams signed up as of today!

Here's some more interesting info and links regarding this project:

An article posted at The Verge:
Math matters: how big data is building the future of everything

http://www.theverge.com/2013/9/26/4766486/materials-genome-initiative-mit-and-harvard

The comments on this article almost, ALMOST, had me starting an account there to let some of the num nuts know they were full of themselves, used in lieu of a few choice adjectives.

Wow, ignorance spans the whole of all subjects, but none more so than Math. Unless, of course, one is discussing politics. A wholly useless exercise.

2 cents, why do I feel so broke? :shadedshu

 

[Arjai]

OK, just now switched my "Device Profile".

School profile is my CEP2 profile.

Tomorrow, in the morning, I am going to test out the speed thingy site, gotta look it up again, to try out their 14 day trial.

If, at the end of the trial, and challenge, if it works well, I may lay down the cash for it. Especially if it works and I go through with getting a SSD, main Drive on this thing.

Crunch ON!!

 

[manofthem]

Since you mention it, I might as well switch the profiles asap and get some new WUs coming. I'm glad I never changed BOINC back to the ssd, as the "disk trashing" is better suited for an hdd.

I switched one of my 8350 rig's over to all CEP2 yesterday and, if all goes well, I'll likely switch over the other 8350 and the Xeon rig over before Sunday

That will be 22 cores/28 threads for 100% CEP2 and can move in another 12 cores/16 threads early next week if we need them

*Note- this is a runtime challenge so we can benefit from any rig running the CEP2 wu's.... a slower rig may turn in fewer wu's then a fast rig but the runtime will be essentially the same

That's good to know, didn't think of it like that, thanks. I feel even better about my second rig since is a low ppd boy

I'll be switching over tonight after work. I thought about it last night but i was in bed with some killer back pain and didn't even sit on my pc yesterday. My daughter had me trapped, and I had to sit through Night in the Museum more than 2 times

So I'll be switching tonight, getting ready early. My buffer is always set low so I shouldn't have to worry about leftover WUs

So basicaly that means in this challenge "OMFD! MOAR COARS!!!" is The Way To Go™. Awesome! ;]

 

[manofthem]

Well, earlier I switched the profiles, and it has taken effect, thanks to a low buffer. As of now, rig 2 is finishing its last FAAH and running 3 CEP2 WUs. Rig 1 is finishing its last 7 FAAH and running 1 CEP2 WU with more to follow. It was easy enough; let's hope it stays running smoothly.

CEP2 FTW


edit: i'm not planning on running rig2 24/7 yet; that's gotta wait til the challenge.

 

[Norton]

we now have 25 teams signed up for the challenge!

Woot!

FYI- check the stats link below (post #2 of this thread) for daily CEP2 info (courtesy of Rob Seke @ WCG forums):

Shows project info on runtime, results, and % of total contribution for each active project (CEP2 is currently running around 7% of the total). It should update at least once a day

Checkpoints

Did they fix the checkpointing on CEP2 WU's yet?

 

[sabre23]

Nope

 

[Lukfi]

If they can't be bothered to do such a basic thing, I can't be bothered to help them with their project.

 

[librin.so.1]

Nope

Please don't lie. Those new [?] shorter CEP2 WUs that are the majority I get these days[1] are not only shorter, but have several times more checkpoints. So I'd say they kinda "fixed" it now. (Not that there was anything to be "fixed", really.)

If they can't be bothered to do such a basic thing, I can't be bothered to help them with their project.

Sir, this statement of Yours is just... just... I can't help it but the implications are so funny I am laughing so much my eyes are full of tears!

[1] approximately 29 out of 30 of all CEP2 WUs I get for a while now are those "new" shorter / better checkpoint'ed ones.

Well thank you, that's what I was asking about.

I don't know what's so funny. My PC is not running 24/7, so checkpoints do matter to me. Having to shutdown/restart in the middle of checkpointless CEP2 running means wasted computing time and wasted electricity.

I didnt lie, i ridiculously suffered around 10k points(which is a big deal for me) during warmup challenge cuz of CEP2 WU's checkpoints. I dont have a luxury of power source 24/7.

If your PC reboots or shuts down frequently you will definitely have some lost wu's running CEP2. In this scenario it is best to run the other projects- this will not impact anything offered in the challenge!

FYI- here's a link to a Tips and Tricks document issued by the Havard CEP2 researchers on setting up your rig... it's a short read but quite informative

*note- also looking for some info on checkpoint improvements/setting adjustments- will post anything useful that I find

 

[sabre23]

^^Thanx, i will look upto it, when my broadband will be working. Currently browsing through 2G Mobile. Hopefully broadband will be restored before CEP2 challenge. Power outage is not only problem i have to deal with.

CEP2 wu uploads can go over 50MB... which sucks balls is quite large and can take a while. Two of my remote rigs typically take 30-60min to upload a single wu due to using a borrowed free wifi signal that is fairly slow (don't run a lot of CEP2's on those rigs )

Here's a link to some info on how these wu's handle checkpoints:

Re: Progress of CEP2 Units lost when computer is turned off

--------------------------------------------------------------------------------
To complete that reply, all progress "since last checkpoint" is lost when switching off, for any science. For CEP2, the 3rd job and 12th job (#2 and #11 in the result log), are the two multi hour steps, no interruption allowed. LAIM has to be on for pausing retaining the task in memory and only hibernation or sleep allows resuming from the last second computed since the full memory state is stored to disk or held in memory at low power.

@sabre23: take care with any bandwidt/data limits you have with mobile internet, we do not intend to increase your bills.
@lufki: hibernation is the best computing related invention after the mouse.

I will fill in the middle column of the table in post 2 ASAP.

@brandonwh64, I believe that you wrote you are in for the prices, is this correct?

@Bow & Vinska: please tell me what your BOINC-names are. Else I cannot find you in the stats.

 

[TRWOV]

second FX8350 online

 

[Lukfi]

Anyway, I attached WCG again and downloaded a CEP2 WU. It doesn't run, BOINC Manager says it's running, but the CPU is idle and there's no progress.

 

[librin.so.1]

[...]
EDIT: gonna switch to all-CEP2 again for the challenge now. Gotta work those FAAH from my queue till the challenge starts

My WU queue is finally clear from all the FAAH WUs and is all-CEP2 now. Took me what? Three whole days?

[...]
@Bow & Vinska: please tell me what your BOINC-names are. Else I cannot find you in the stats.

Mine is librin.so.1 and Bow's is BowHunt3r, AFAIK.

Also, Chevalr1c, PROTIP:

To defeat the Cyberdemon, shoot at it until it dies.

Spoiler

To easily see the member's name, assuming he/she already has The Badge™:

Cheers!

Are You in the advanced view? i.e. Are You sure You have any WUs actually running?

Because, You might be affected by this, like I am. So if You're in the basic view, it might say it's running, while in reality it tries to access the feeder and get some WUs, but can't. This way, ending up with no WUs and just retrying until the feeder is up again.

 

[Lukfi]

I am in the advanced view. The WU was downloaded, but didn't actually run even though the status was "running".
