That one took a while... Next will be 7th star silver.

8th star next.

Next will be fourth star Ruby, or a seventh star, depending on how much work some projects generate.

So my guess was wrong.

No idea what will happen next. Maybe 5th star gold?

Busy few weeks at the moment with various DC competitions taking priority over chasing hours so next badge will probably take a while.

I doubled the number of running tasks from 4 to 8 (doubling their runtime to about 2 minutes), and it now seems to be tracking accurately. Thanks for the suggestion.

I'm running the project "Private GFN Server" (which, despite its name, is not private), and this project has two extremely short applications, GFN-13 Prime Search, and GFN-14 Prime Search. In order to ensure that my GPU is fully utilised, I'm running 4 of these at a time, GFN-13s taking about 1 minute each (so 15 seconds per task), GFN-14s taking about 2 minutes each (30 seconds per task).

Looking at my daily hours reported, I'm seeing drastic underestimation of these - particularly GFN-13. If I look at my last day of work on that computer (image available here), you'll see that there's ~16.6 hours of data there based on the NCI tasks. Collats Sieve is running on the integrated GPU, so you can ignore that. The only tasks there running on the dedicated GPU are Asteroids@Home, and GFN-13. Asteroids seems to be tracking correctly @ 5.25 hours, so there's around 11.35 hours left over, all of which were presumably occupied by GFN-13.

Now, theoretically, GFN-13 should be counting 4 hours for every actual hour it runs, since I'm running 4 tasks at a time. There's likely a fair amount of overhead involved in starting and running them considering how short the task is, but this is definitely not enough of a difference to turn ~45 hours into 0.38.

I haven't paid as much attention to GFN-14, but it seems like it may have had similar issues, although certainly far less drastic ones.

I don't really know what's happening here. Maybe WUProp is erroneously tracking CPU time, maybe it just can't cope with such short work units and misses most of them (this would explain GFN-14 tracking better), or maybe it's something else entirely, but the GFN-13 data is definitely massively under-reporting.

These tasks do run at 0.01 CPUs + 0.25 GPUs, so maybe it's recording the CPU time at a 0.01 "multithreaded" multiplier? 0.38 hours * 100 would be almost exactly what I'd expect, with the remaining handful of hours being easily explained by the start/stop overhead.

Looking at the global stats it certainly doesn't seem like the top users there are having that problem, though. I'm just confused at this point.

Well that didn't take long.

Just noticed that the previous post didn't work because this forum doesn't support https embeds (why?!), so that was actually meant to be:

and now:

Second badge next.

Those first four stars are going to be tough to upgrade for a while now. Not sure if I want to bother with that or fill out a full second badge first.

Returning from a six year hiatus to finally fill out that fifth badge slot.

It's very surreal to see the people I last saw talking about having to run unstable alpha apps for their 5th star "suddenly" on their 28th... Hopefully I can make up for lost time.

So what happens when you get a 6th star?


Nothing

It seems only fair that you get a second badge or some other way to incorporate a 6th into the existing badge


This was discussed when STE\/E and zombie hit 5 sapphire stars (which was at that time the highest possible badge), but it was decided that further stars would not be implemented due to the limited number of projects, and the necessity to participate in alpha projects with little work or have participated in now-defunct projects for badges beyond the 5th.


Would it be possible to add a row across the top of the Reported Data table listing the total Running time. I suppose if it's easy the Total Pending might as well be totalled too.


Free-DC does this - just replace "&name=xxx" with your userid, or use the in-built search function. Would be nice to have on the site proper though.

Ka-ching! Good night for me:

Third star to gold and fourth to silver simultaneously. Still a long way off getting that fifth star. I reckon I'm just going to farm as many PrimeGrid apps up to 2500+ hours as possible in an attempt to secure a bit of a buffer there.

After finally getting everything set up and connected to the internet after moving house, I have an emerald star!

Next will probably be a gold third star.

Ding!

On holidays in Melbourne right now, but one of my home servers has just uploaded a WU for CAS@Home that got me to this:

→

I'm only two apps away from turning the first one Emerald, one of which should be done in a day or two. I'm also relatively close to a third gold and fourth silver, but they won't be happening for a while, as I'm focusing on projects that my team needs help in at the moment (and also, I cbf playing with servers during my holiday).

Finally got an upgrade!

Only 5 apps from my first Emerald, 2 apps from my second Ruby, and 8 from my third Gold.

I got mine on eBay as a refurbished unit for about $100

Hot damn, don't suppose they have any more to sell? That price is insane!
