Formula-BOINC Sprint #10 13th-16th July 2017

Postby UBT - Timbo » Mon Jul 03, 2017 9:49 pm

Hi all

The next FB Sprint will be held as from Thursday 13th July at 23:00 UTC (12 midnight BST) until Sunday 16th July at 23:00 UTC (12 midnight BST).

We did really well in the 9th Sprint, for which the chosen project was Collatz, earning a commendable 4th place.

If you want to join in, then check the Formula-BOINC website around 12 midnight BST on Wednesday 12th July and the next project will be announced.

Oh great, another night up until 1AM configuring hosts :(

Why can't they start these sprints at 7PM? :D

Hi

What about these ones then?

Hi both

I think I've figured out the timings of these Sprints.

Obviously there is a date link to the respective F1 race on the Sunday afternoon, which normally starts at 2pm local time (although there are a couple of night races, which don't fall in line with this) and will normally end within 2 hours of this.

The race ending at 4pm local time, is when the end of the Sprint occurs. But the catch is, in what time zone, is the Sprint based?

From what I can gather, for some European races, that end by 4pm local, the corresponding Sprint ends at a time which 5 hours later. (ie 2100 UTC).

If it's 4pm locally in Europe say, then a 9pm time zone would be somewhere like Moscow.

For the Canadian GP, which ends at 4pm local, which is 9pm UTC, the Sprint ends at 4am on the following day - again that places it around Moscow time zone.

So, that's all I can say - FB uses whatever local time it is in Moscow, (when the respective race ends) to set the start and ending times for each Sprint.

regards
Tim

Hi all

Seems like the FB website has got a Python scripting error...just as they were about to announce the chosen project for this weekend :-(

Hope they fix it in time.

Hi Tim,

I'd noticed that, seems I could have had an early night after all!

Hi Mark

And now the entire FB website has errors - it was just the Sprint section before...though it might be that some pages were in my local cache...

Hi Tim,

I think it's the whole website, I can still go back pages and fetch the cached versions but any reloads bring up the error page.

I suspect it's the banner at the top which is supposed to state the sprint project and can't find it.

Oh well, got to be up for work in the morning so suspended network access on most hosts at the moment and hoping they're already on the right projects. If not, it might be a busy morning tomorrow! :D

Hi

Well this is interesting. The my PC hates the CPU version of this and shuts down as soon as it starts! So it's just the GPU version I'll be doing!.

Hi Mike

TBH, I would only put the GPU to work on GPU-supported projects - Asteroids offer a fixed number of credits per completed task and for the CPU, the "payback" per task isn't worth it compared to the time taken per task (IMHO). Times of circa 5,000 to 10,000 seconds are quite usual... :-(

GPU tasks can be completed much faster (between 4 to 10 times) and the credits are "OK" without being exceptional. But every team will be in the same boat, so no issues there. ;-)

So, I've got me some Asteroid GPU tasks and I'll do a side crunch on SRBase on the CPU's.

Have now set PC to "suspend network activity" until after midnight tonight, so all the credits earned today, will be awarded tomorrow and will count towards the Sprint total :-)

regards
Tim

Hi All,

Asteroids it is then :)

It does seem strange that of the top five hosts on Asteroids, only one of them has a GPU and that's a GTX670 from 2012! I think Asteroids is one of the few projects where the GPU application isn't a big step up from the CPU one.

For example, a host with an E5-2683 @ 2.4 GHz completes a task in roughly 6000 seconds while its GTX1070 takes about 1000 seconds. Not a huge difference in processing times compared to other GPU enabled projects.

I'm going to try both CPU an GPU tasks to begin with and see how they work out.

Hi Mark,

Fair enough :-)

My i7 was doing Asteroid CPU tasks in about 7,000-9,000 seconds, (I seem to recall), while I have 2x GTX970's, which are turning in tasks every 1,400 seconds.

So, 480 credits per CPU task every 1.5 hours, compared to 960 credits, every 24 minutes for the GPU.

Of course, with a multi-CPU PC, such as a Xeon, the numbers do work out better for CPU's as you can crunch (say) 32 tasks in the same 1.5-2 hour time period, with a subsequent benefit of 32x 480 credits = approx 16,000 per period.

That's around 192,000 credits per day, via CPU. :-)
Or around 28,800 credits, per day, per 1x GPU

Tim

Hi Tim,

I would have expected a GPU task to have been at least ten times faster than a CPU task but that's definitely not the case for asteroid tasks.

Once I get back onto the internet I can have a look at some of my actual numbers but I suspect the 32 core Xeons are going to do well on this sprint :D

Unfortunately, I don't have a GPU but, from memory, I think I get about 15K/day on Asteroids and, as Tesco say, 'Every little helps'.

Hi Chris,

With Asteroids, you don't miss out as much with not having a GPU as with some other joint CPU/GPU projects so have at it :)

I wouldn't call 15k a day 'little' :shock:

All figures are relative I suppose but compared to some of the 'heavy bats' in the team it feels quite small to me. However, I enjoy it and it keeps me out of mischief...

I've just noticed on the Asteroids server that there are zero tasks waiting to be sent. Fortunately I have a full cache but I'm not sure it will last for the entire sprint. Hopefully more will become available but if work is in short supply it could skew the results a little.

I remember being extremely pleased to reach the heady figure of 1k a day when I first started, in those days though it was unheard of to have more than one core in a CPU!

Chris.

They quite frequently run out of work but I would have thought someone would have warned them about the sprint? The other problem is having a wingman, you could quite happily finish off a hundred WUs then have them sit there and not be validated until after the sprint has finished.
