Hi

A couple of days to go - what do we reckon it's going to be? Have a look at the FormulaBOINC site http://formula-boinc.org/sprint.py?lang=en&year=2017 and post a guess!

I'll start...

For no better reason than a guess, I'll go for Universe@home. No idea what it's like - seems I did a few a couple of years ago but can't remember anything about it. Not sure if I really want it or not!

Hi Mike

I don't think it'll be a GPU project this time as 3 of the 7 Sprints so far have been CPU/GPU projects. (And there are still another 5 left in the frame: Asteroids, Collatz, GPUGrid, MilkyWay, PrimeGrid) once SETI is crossed off (which it hasn't been yet).

That leaves CPU projects. Wanless is only supported by Linux so that's out. There's little or no work from these: BURP, Citizen Science Grid, FiND@Home, PRIMABOINCA, theSkyNet POGS and The dDM-Project.

Which leaves: Cosmology@home, DENIS@Home, Enigma@home, Leiden Classical, LHC@home 1.0, NFS@home, SRBase, TN-Grid, Universe@Home, VGTU@home, Yafu - all of which could do with being the chosen one (for any month, not just this one).

I think I'll plump for......Leiden.....or maybe LHC?....or maybe DENIS ?

Leiden then !!

I'll guess at LHC or at least hope for that as it is the only one I won't need to register as a new user for.

Since we're having guesses, I reckon it's between Enigma, LHC, NFS, SRBase or Universe.

My choice would be Enigma.

Hi all

Looks like DENIS might be out of the running as the website is down and not accepting any crunched data for the last 12+ hours. :-(

What work I have completed has a longish deadline of 30th June, so I hope the website is back up and running before then else the time would have been wasted.

Hi all

DENIS@home website now says:

"Your PHP installation appears to be missing the MySQL extension which is required by WordPress."

So, one hopes they made a backup of what ever they had online, as whatever they are using as the front-end seems to have been compromised.

OK, so they've announced LHC as the sprint project but I can't get any tasks for it. Every time I try it just says that there are no Sixtrack tasks available.

Well it took 20 minutes and about 30 updates but I got some now.

HI

I'm afraid I was hovering when it was announced and managed to snag 140 of them. AFAIR 6 track has been hard to get as they were concentrating on the projects that required the instalation of VirtualBox. I had it installed on the old PC but it used too much RAM and woiuldn't install at all. Didn't get round to installing on the new one.

Congratulations Chris, I'm still trying :(

If this keeps up I might have to try a different subproject.

Finally managed to get 120 on one host, still nothing on any of the others :(

They still have other work to be getting on with though :D

Hi all

I just got in from work and I'm happily downloading lots of LHC work ;-)

Don't forget to SUSPEND network activity until late tomorrow night !! so grab as many as you can - I've set my cache to 5 days !!

regards
Tim

PS: There are nearly 2 million LHC Six Track tasks available right now, so just be patient if you haven't got any yet !!

I've managed to get another eight! in an hour, at this rate it'll take me five days to get one days worth of cache!

Hi Mark

My octo-core grabbed 84 tasks and while my back was turned (and I was downloading some more MOO tasks) it uploaded 4, leaving me with 80 - they start off as needing about 4 hours each - and yet 2 were uploaded after just 40 minutes and one was finished after 25 mins !!

At that rate, I'll have crunched them all within about 8-10 hours.

I tried to download more, by increasing my cache to 10/10 and I got this message:

21/06/2017 23:33:20 | LHC@home 1.0 | This computer has reached a limit on tasks in progress


So, they are stopping anyone from building up too many in a cache.

regards
Tim

Hi Tim,

UBT - Timbo wrote:Don't forget to SUSPEND network activity until late tomorrow night !! so grab as many as you can - I've set my cache to 5 days !!

It would be nice to have the option! Almost all the tasks I manage to download are crunched and returned before any more appear :(

I've even had to resort to allowing some of the other sub-projects to be downloaded as three hosts have been asking for work for the past eleven hours and got none at all. I'm now checking finished tasks to see what's the second best choice as I don't see me getting very far with just six track work.

UBT - Timbo wrote:PS: There are nearly 2 million LHC Six Track tasks available right now, so just be patient if you haven't got any yet !!

Still 1.9 million of them left to be downloaded. Either they're topping up the server quickly or no-one's getting many ... I expect the latter.

I have two identical hosts, one has 576 six track work units downloaded, the other has 14. Both connected at the same time, both asking for work at the same time. The first one is now off the internet so it won't be uploading finished work, the second has work for about an hour.

Hi Mark

I suspect that LHC don't update their Server Status that often then....which then causes misery for everyone expecting work as they then assume that it's their PC or their settings that is the cause.

Despite my predictions, overnight, some of the LHC tasks have taken a lot longer to complete...whilst some indeed only took 30+ minutes, I've got a couple that took 9+ hours plus one that took 6 hours :-(

At least the credits given are proportional to time taken, UNLESS you find that for the quorum, someone else crunched the same tasks a lot faster and hence you get a much lower credit. :-(

The average time to crunch for the 32 core PC is about 1,500 seconds, but I've received lots of credits in the range 85-95 and for the same amount of time, lots in the range 4-5. (I know the BOINC credit system isn't fair, but it is what it is...just have to return work before someone else does (assuming they have a faster PC).

My 32-core was being totally starved of tasks, until about 5am this morning, so as a back-up, I was doing some Enigma tasks as I need to catch up a bit on that project. But I now have 320 tasks, so that'll keep it busy for the day !!

One assumes that FB gave LHC a "hint" that they would be chosen...but maybe LHC couldn't produce enough work in time?

Oh well....one assumes every team will be affected so no need for us to assume we'd been stopped from getting work (even if other teams had gobbled it all up before us !!).

Tim

Hi Tim,

Credits do seem pretty random, most of my tasks on the 32 core take ~300-400 seconds and receive anything from 0.84 credits to 20.49 although I did get a huge 117.77 credits for a 11,221.51 seconds workunit! :shock:

Just had a quick check on their server:
Untitled.jpg


Workunits available is 1.8 million when the status was updated at 08:14:47 UTC (about an hour ago)

Like you say, I think everyone is in the same boat.

Mark

[edit]
Just checked again and all's well and the workunit status has been updated again so it's pretty much real time.

Hi all

I've just got back from my monthly charity meeting in Cambridge and I've now enabled internet access to the PC's crunching on LHC...so expect to see a slight "surge" in our Team credits on the 2am stats ;-)

I took a look at the FB Sprint status page and we're currently in 7th place, just 68 credits ahead of "Rechenkraft.net" and 7,193 behind "L'Alliance Francophone".

EDIT: In fact the surge is 27,617 credits...enough to (maybe briefly) put us into 4th place with 51,168 - about 4,500 ahead of "Russia" and about 3,200 behind "SETI.USA" :-(

So, this might be a close race over the course of this weekend !!

regards
Tim

Hi Tim,

I finally managed to get enough work to allow me to turn internet access off then back on once the sprint started but only for a couple of hours or so. Nowhere near as big a 'surge' as you produced though :)

We started off in ninth place and were up to fifth by first thing this morning. Dropped down to sixth now as Seti.Germany have passed us but it's a relatively close thing between 6th to 10th positions.

Looks like it might be a repeat of the Moo sprint and end up very close and decided in the last few hours.

Mark
