Formula Boinc Sprints 2018

Now it's back down to 115 W (50 % of hardware threads used). This application leaves me puzzled.

IIRC, this is the first time since I joined this forum seeing Stefan puzzled.
This VGTU is so mysterious.

 

[biodoc]

I guess the French team was bunkering.

 

[biodoc]

Nice effort!

 

[ao_ika_red]

My theory is due to the nature of CMT, some part of the core is taking big performance hit. So, I need some validation from anybody here that also uses Bulldozer CPU and its derivatives.

And somehow, I proved myself wrong.
When I ran just 2 tasks concurrently, it needed 13 hrs+ per task compared with 4 tasks @24 hrs+ per task. I'll try again with 4 tasks configuration, but this time I put my memory in overdrive mode.

Team Planet 3DNow! is active in the sprints and partially in the marathons too. I added a link to their forum in post #50. Judging from their sprint points so far, adoption of AMD's latest and greatest CPUs among P3DN members seems lacking.

Somebody in L'AF's forum was wondering why CNT aren't more active. Of course with a project so easy to bunker like VGTU, CNT should normally drop big bunkers late in the game. But since CNT are currently desperately trying to remain ahead of SETI.Germany at PrimeGrid, I don't expect them to perform too well in this sprint.

Day one of VGTU sprint is in. We are doing well and in fourth. L'Alliance Francophone is putting up a fight for third in the sprint and second in the marathon. Can we find more, more, more?

Unfortunately some time today I believe the smoke came out of a piece of hardware. I am not exactly sure which component gave up the ghost as of yet, machine was running "not right"......lagging, unresponsive and such. I blamed it on Teamviewer and the WIFI connection when it started being a POC. Gathering hardware to get it back up and running though (hopefully) pending what went wrong. (read as too much accumulated "extra parts")

RIP SSD, back up and running GTG

Welp......dead just dead she served a good hard life......RIP old girl you did well.

 

[StefanR5R]

Wow. I am reading some very outdated info about VGTU at other teams' forums.

"It's about cryptography."
(VGTU is more of an umbrella project, with focus on IT/ CS/ Applied Mathematics. They had a cryptography research application going until Summer 2017. Now they are researching optimization algorithms, with a civil engineering problem as a benchmark.)

"Only Intel CPUs perform well on it."
(Current AMD CPUs work as if they were specifically designed for VGTU's current application.)

"You need to switch off Hyperthreading."
(AFAICT, there is a small HT benefit on recent Intel CPUs. Not to mention proper scaling with AMD's SMT.)

When I ran just 2 tasks concurrently, it needed 13 hrs+ per task compared with 4 tasks @24 hrs+ per task. I'll try again with 4 tasks configuration, but this time I put my memory in overdrive mode.

Third batch results are in.
Faster memory do the trick (1600CL9 before, 2133CL12 after, no sub-timings alteration). I can shave off my completion time from 23-24 hrs each to 20-21 hrs each. I can see that my core clock now often jumps to 3-3.5GHz instead of just locked in 2.7GHz.

A bit late, but here is day two of VGTU.
Hanging on in fourth, which is great as we are split between two races this time around. If we ever get to throw all our resources at one project....look out!!!!
Gaining good points on the teams above us in the marathon.....ssssssssshhhhhhhh

1 Gridcoin ..............................25 .........4,764,338
2 SETI.USA .............................18 .........2,285,410
3 L'Alliance Francophone ......15 .........1,388,653
4 TeAm AnandTech ...............12 .........1,040,087
5 Overclock.net ......................10 ............822,794
6 Planet 3DNow! ......................8 ............267,337
7 UK BOINC Team ..................6 .............239,416
8 Rechenkraft.net ....................4 ...............87,749

WOW, my stats say I have done 108,175 of that one million @! With one threadripper ?

Man, these two know how open their floodgates properly.

User count according to stats-free-dc's last update:

SUSA: 10 users yesterday, 8 users today
LAF: 16 users yesterday and today
TeAm: 14 users yesterday, 12 today​

"Math awareness" according to PrimeGrid:

SUSA: 0.6 M
LAF: 1.3 M
TeAm: 7.9 M​

While I'm trying to get a few more VGTU tasks done now, I am already looking forward to the next sprint which is not concurrent to any other event.

 

[ao_ika_red]

I'm a bit worried about OcUK. Once our formidable rival in Sprints, now they look very, um, silent. Are they bunkering or something?

 

[StefanR5R]

I recall they are taking a sabbatical from Formula BOINC.

Try different ISP. I also had the problem earlier and solved that by using my mobile phone's internet.

I tried that, but it didn't work. I think that may be how I got the problem in the first place.

 

[TennesseeTony]

Check your timezone is accurate, but I have no idea why. My memory is such crap, when I get a thought, I just run with it.

 

[Ken g6]

My clock is fine.

I never want to do VGTU again, unless I get the chance to rewrite their application.

 

[Orange Kid]

The final results are in for sprint two...VGTU.
We ended in a respectable fourth.
The Czech team edged out Rechenkraft for the number 8 spot and USA came on in the last moments to push SETI.Germany out of the points all-together.
Another sprint is set for this week......

1 Gridcoin ................................25 6,973,715
2 SETI.USA ..............................18 3,470,778
3 L'Alliance Francophone .........15 2,038,047
4 TeAm AnandTech ..................12 1,517,274
5 Overclock.net .........................10 982,034
6 Planet 3DNow! .........................8 490,681

EDIT, The second F1 and Vettel repeats with another win!!!
April 8: Bahrain Grand Prix
1. Sebastian Vettel, Ferrari

Just like the F1 race, I was anxiously waiting until the deadline as we're so close with OC.net but unfortunately I fell asleep in front of my PC.

What a race it was. Sorry for Kimi's mechanic though. Wishing him a speedy recovery.

Daylight Saving has me screwed up. The project will be announced at 9am CST right?
