Not sure I understand what you're saying. If he was running normally then his results would be trickling in all the time as they all have different runtimes. To return work units in the last hour every day sounds planned to me. I just have no idea why anyone would want to do that.


I think the idea is that if we knew they had done so much work we'd mobilise more resources. By storing up results and dumping them just before the end we don't have time to respond. If it is a sieving challenge then it doesn't matter if you are first to report. If it is prime search challenge then you are saying you'd rather win the challenge than find the prime. I know my preference but the other is rational.

Why it was done each day I don't know.



There are numerous possible reasons a user might have a stair-stepped pattern in returning results. For example, those with metered internet connections may be connected only for portions of the day such that the work they do over several hours can be uploaded largely at once when they reconnect each day. In such cases, the user would never reached a smoothed pattern.

The CNT member in question for this year is certainly not the only user to have such a pattern in challenges in general, nor is that something unique to CNT team members overall.

CNT has certainly had some dumps in past challenges (i.e., a sudden upload of work at the end inconsistent with the pattern across the first 90% of the challenge). My point was that seems quite strongly not to have been the case in this challenge.

It wasn't exactly a planned dump. Venec ran that way all 7 days and just timed his last stair step increase perfectly for the challenge end.

I was happy with my performance, but disappointed that we just missed on 2nd as a team. The upcoming 3-day sprint will be fun...will have to see what I can put together to answer that CNT power.. ;)

Looks like the normal dump from the cnt folks happened a day early. Man I wish I had full use of my systems... any hoo...

Go AtP !!


$20 would buy you 20 TSC 3-core droplets over the remaining time in the challenge...

Can I request a boat as my luxury item?


Rick already beat you to it. :)

All the Journey, Eagles, Styx and John Denver songs.



Allowed a little longer list, all of those would be there for me as well.

Ok, I'll have a go at it...


1 Escape (Journey)
2 Point of No Return (Kansas)
3 Running on Empty (Jackson Browne)
4 Chronicles (Rush)
5 Back in Black (AC/DC)
6 Madman Across the Water (Elton John) *tough decision on this one as there are others I could easily substitute
7 The Lord of the Rings: Return of the King (various including Annie Lennox)
8 Rubber Soul (The Beatles)

Lord of the Rings (I can just read this one over and over)

The Tao of Pooh by Benjamin Hoff (I think this qualifies as a religious text--great read if haven't done so yet)

My luxury item would be a case with a very generous supply of food seasonings appropriate for seafood and tropical fruit/plants so that no meal would ever have to be bland.

Very Nice! You should be #1 in rank for TRP before the day ends as well!

Just spun up another 10 TSC instances to help close the gap with our Czech friends. That is going to tap me out for this event.


...And yes, we all know that this is a sickness! :)

With the TSC instances why is there such a massive variation in performance? Looking at Scott's tasks the same FFT size can run anywhere from 15K-30K seconds and in the end both provide the same credit.


These are VMs provided to TSC by Digital Ocean. They have other clients not related to PG who are running their own stuff across DO servers. I imagine that we take a performance hit when either others on the same physical server CPU are running software with similar demands/instruction set needs as PG or, indeed, when multiple PG users are sharing their 3-core instances on the same physical chip. This may be especially true for apps that are using the AVX512 instructions, like LLR.

The Czechs have jumped a bit ahead of us...but we have a secret weapon...Looks like Z-san just began switching over to TRP. :)

Will see what that affects then I'll look at adding a few more TSC maybe.
