Re: Africa Rainfall

Hey Guys, how's it going?

Was about to say its a pity that Dave has left, but I just read that he's back which is great news. Honestly I don't think there's another team that has a WCG Stats site as comprehensive as what Dave has put together.

In about a week I will be rejoining the team and hopefully staying long term. I just built a new Server (2x 64c EPYC 7003) which I am going to only run on CPDN and WCG, so hopefully that will do some decent numbers.

That's very kind ncoded, thank you. It looks like I'm back for good then! I've even started crunching again, albeit one core on a low-end NAS. I'm thinking that I'll replace the graphs with Google Charts (which I don't think existed when I wrote the stats stuff in 2015). That will allow some better graphs, with interaction.

Hopefully other people will come back on board, particularly those with solar panels or broken boilers biggrin

By CPDN do you mean ClimatePrediction.net? I looked at their website when WCG first went offline, and then like now it appears to be dead in the water. There's been no news, or tweets or anything like that, for a couple of years, although it does still seem to be running. Am I looking in the wrong place? I hope someone is doing something with the data.

Re: Africa Rainfall

Boiler not getting looked at till Monday, seems nuts to just use electric heaters so supplementing with old servers. Annoyingly my Supermicro motherboards seem to have both died, one is totally dead the other is only running one CPU, don't think I'll be buying them again.
Still shopping for Solar panels, had 3 quotes so far, slowly refining options but price creeping up.
4kw, 9.5kwh battery = £12.3k
5.4kw 6.6kwh battery = £13.5k
6kw 10.5kwh battery = £16k
I was quite surprised how pricey they are, naivety on my part I'm sure.

Re: Africa Rainfall

Yes climateprediction.net is the main project, with the BOINC part being at cpdn.org.

I believe CPDN its actually the Worlds largest BOINC project, as confirmed in the last BOINC Workshop; although I am not sure what metric they used. CPDN is basically what the "BBC Climate experiment " project turned into.

The reason it looks dead is because very few tasks are issued. I would say perhaps on average just a few batches of 1-5K tasks every month or so. And when tasks are released they go pretty much instantly (within 3 hours) due to the large numbers of people waiting for tasks.

The project is one of the more demanding BOINC projects, both in terms of the length the tasks take to process, but also heavy Memory and L3 cache usage.

Most of the tasks that get issued are for Linux, which also require you to install the 32bit libraries.

CPDN is fairly unique in as much as they directly show you the exact Research publications that you have provided compute for. The only other project that does this is GPUGrid.

This is an image of what we see when we login, and view the user publications page:

Re: Africa Rainfall

Yep, that's the CPDN I've contributed to before (first time 2012, last time 2018). The website isn't looked after anymore it appears, but I guess they don't have to if the work units go very quickly anyway.

Re: I'm back!

FYI, I've just done a small makeover to the graphs on the "Recent" and "Projects" screens, courtesy of Google's more modern (and usefully interactive) charts library. I'll do the graphs on the "Compare" screen at some point soon.

Re: 3 years

Morning all. Hope everyone is OK.

While the team's output is lower than in previous times, it's still plodding along. A bit like my output! Hopefully as the availability of workunits seems more stable, a few more members will return.

Congratulations Alan for your contribution applause

Keep warm and safe everyone.
