21) Message boards : Number crunching : Two Trillion events reached by the Test4Theory BOINC-CernVM project !!! (Message 1696432)
Posted 28 Jun 2015 by Profile ivan
Just received this message. Congratulations to all involved!

Date: Sun, 28 Jun 2015 06:40:57 +0100 From: Ben Segal <xxx@cern.ch> Subject: Two Trillion events reached by the Test4Theory BOINC-CernVM project !!! Dear all, Today we reached the total of 2 Trillion events simulated since 2011 by Test4Theory volunteers for the CERN PH-TH project MCPlots. We just announced this on the Test4Theory project News forum, and thanked our volunteers, but maybe a wider announcement would be in order? For example, back in September 2013 when we passed the 1 trillion mark, a lot of tweeting was done and CERN published an excellent article about the project: http://home.web.cern.ch/about/updates/2013/09/crowd-sourced-computing-platfo rm-reaches-one-trillion-events . And since then most of the LHC experiments have started BOINC-CernVM projects. Anyway, please feel free to forward this message as appropriate. Best wishes and thanks to all those who have helped to achieve this result, Ben and the Test4Theory team

Thanks for the info, Matt. Getting some cricket graphs back up would help us armchair quarterbacks second-guessing what's happening at any given instant. :-)

A midsummer's night dream?
Tullio

Night dream right. It's so much light.

Yeah, I spent a day^H^H^Hweek in Trondheim one summer. ...and took a 3-week cruise from Mawson to Melbourne starting about December 7th another year.

Strange...
I have a strange feeling of emptiness.

Mmm. Came in this morning to find my wall of gkrellm monitors largely black. Well, the 12-core is down at the moment; I tried finally to put it and the dual-20-core servers into a rack yesterday, but it seems when I rebuilt the rack I put the uprights fractionally closer than the standard rack dimensions, and the 10C's rack rails are about 5mm too long, fully collapsed, to fit.
But one 20C's display is blank, and the other shows only three jobs running.
After a bit of panicking, I eventually realised the fault was in Berkeley, not North Heathrow. Should be a trifle quieter in the server room today.

I'm expecting a quotation on something not quite that big soon. Chap in the department had an Intel box for evaluation a couple of years ago -- it had a solid row of dual-width PCI-e slots across the back of the unit.
I'm...

I can live in my office if I sell my house, right?

I'm sure it's been done...

*sigh* Oh well, then. Lesson learned. I don't know what the max value for <save_stats_days> is... but 36500 is apparently too much. 3650 works, so for now, I'm going to try 5000 and see if that works. Let that be a lesson to all of you, in case any of you were wondering about that, or thinking of extending your stats out a bit longer. You can absolutely for sure do 10 years... but I don't know how much farther you can go on that.

Sounds suspiciously like it might be 32767 for some reason -- max value for a signed 16-bit integer.

In use, the days get multiplied by 86400 and the result needs to still be a positive 32 bit integer. So it seems 2^31/86400 = 24855 would be the maximum.

Ah, yes, that sounds more plausible. Thanks Joe, I was hoping S@H wasn't still running on 16-bit PDP-11s!

Yes, that's about it. Another way of describing the UK system is to say that if you want the charity to get 1,000, you only have to write a check for 800.

Richard, your spell-chequer is borked!

ivan, I just don't even like to think what the hell you used to get to where you are. It makes me do things like think how my wife would react if I re-mortgaged the house to buy a rack full of Titan X...

Well, you've got the same RAC as me, but a few more computers :-) Time was I always had faster/better computers at home than at work, but that's changed. At least I'm allowed to run "stress testing" at low priority, it's all Science after all. That pair of 20-core machines I got recently help, but with a 100 WU limit, they don't hold much of a cache!

Graham Middleton, I have you firmly in my sights. According to boincstats I'm only about a month from overtaking you to 21st place in the UK. :-)
Well as I said to the meet last week, I'd just slipped up another place overall -- in less than a month I'll be up another.
And from there? WORLD DOMIN...
Sorry, was I doing megalomania again? I do apologise!

My UK domination is under threat from my friends at Imperial College, "keeping their server room warm" by running S@H while there's not enough LHC jobs to crunch. Thankfully we started 13 TeV running last week, so maybe they'll get back to HEP stuff soon. Otherwise they'll overtake me around August. I must speak sternly to them at our meeting early next month -- they should be doing CMS@Home(pre-beta) instead!

Just to report that the mini-meet in London went very well with 7 people being there.

Who were they Chris?

I don't remember.
I think it was me, Anniet, Chris S and Graham Middleton down one side of the table; Uli, Woodgie and Havoc down the other -- but I may have got the aliases wrong (problem with long-distance high-speed motorcycling sans earplugs -- you lose high frequency hearing and catching conversation in a noisy background is difficult). (I thought there were eight at one point, but that may have just been the £5.xx/pint Punk IPA -- I went around to Clerkenwell Green later and in The Crown local lager was 'only' £5.00 :-). <sheesh!>
Bernie is going to get a lot of spam in my name as I used his mobile phone number to verify my usage of the "free" WiFi...

Or yell "I'm an Alien"
Always tell the truth,
#I'm an alien, I'm a legal alien. #I'm a nAustralian in Lon-don.

And after the anal probing, they will buy you a beer :))
Ah, yes:
#It's no fun, being an illegal alien!

I'll be the long-haired old geek in the CMS cap.

There will be a mini or maxi Seti Meet on the second of June in London at noon at the Anchor Pub by the London Bridge.
Chris kindly reserved us a table.

Remind me how to recognise you. :-)
As reported elsewhere, I have to go to an art exhibition in Clerkenwell Green at 18:00, so I'll be hanging around in the city all afternoon. Any plans for, e.g., a visit to the Science Museum? (BTW, I have free public transport within London, so anything considered -- apart from a trip back out to Uxbridge which would require an almost immediate return the City.)

Posted 28 May 2015 by Profile ivan
Well, the VBS file generated an error again. Same thing, different character. I don't know how to generate the invalid character, but it was the fancy version of the ("). I also found another invalid character. Not sure what it was or even how to describe it. So once again I fixed the file and saved it. This time I brought up the command prompt window and manually ran the file. No error this time and it worked as advertised. It restarted sidebar.exe. WooHoo! :D

If you cut-'n'-pasted from a web-site you may have picked up Unicode or other characters that look like normal ASCII characters on the screen but are encoded differently. I sometimes encounter this when e.g. copying article titles from a journal's page to put in my publication list.

After Looking at the BOINC Log File its saying, "Unsupported Drivers" Or something along those lines and fah is completely failing on me. Under the Driver Manager in Mint 86_64 I have no device listed at the top of the Pop up Box for Mate Rebecca 17.1 so it looks like I'm going to have to do some digging around to get the GPU Drivers installed Manually.

Try this post to help you get started.

Just tested with IE/Chrome/FF on Windows and LG Browser/CM Browser on Android and the site works with every browser.... except IE. I wonder if it works on Edge. Anybody here who can test?

Running Spartan/Edge right now on my Win10 test box -- I can see the referenced page without problem.
