It's great for the AP27 sub project that's for sure.

Thanks very much for organising this focus on the GCW project.

Till next time :)

Making a late start due to work commitments.
Better late than never I guess. :)

Thank you to those who helped organise this focused event on the PSP subproject.
I at least received a new badge out of it.

I've just realised the start time SUCKS for this comp!! LOL
I'll be at work! I'll miss out on at least 6hrs of crunching :(

That's a better alternative than starting early though.

What time do you start work?
Challenge starts at 6am (Melbourne, Sydney, Brisbane)


Start at 6am mate.
I'm up at 4:30am for work every day.

There are ways & means.


Yes...if only I could access BOINCTASKS from my phone!

She'll be right. I'm not a serious contender with these comps anyway. Its a bit of fun :)

I'm going to use the information about minFFT and maxFFT to run as most task as possible on the 12 core Xeon. Something tells me that running 2 tasks with 6 cores each may be the best option, but dependant on the FFT size, 3 task using 4 cores each might also be possible :)

I am guessing your xeon is similar to my X intel CPUs.
You will probably be best running only 1 task at once.
Unless you don't have enough cache (L2 + L3 for xeon?) but even then 1 task may still be best.
With L2 + L3 - I think - and I just made this up - L2 + 1/2 L3 - is going to work.
As an example, running all 16 cores on a 9960X, which then has 16Mb L2 cache - I know mid 20s will be fine, but high 20s and low 30s not. L3 cache on a 9960X is 22 Mb. 16 + 11 = 27 which is about right for as much 'working in cache' as you could hope for.
Edit: Mind you I run 2 x CUL or 2 x WO0 which uses about 32Mb and it only slows it down a bit - to about the speed of a 9980XE.


I'm guessing that's the power of AVX-512 right there.
My testing came up with the following -

AMD

3900X running 1 task x 12 cores = 41,000 sec run time.
3900X running 2 tasks x 12 cores = 66,000 sec run time.

1950X running 1 task x 16 cores = 46,000 sec run time.
1950X running 2 tasks x 16 cores = 87,000 sec run time.

3950X running 1 task x 16 cores = 52,000 sec run time.
3950X running 2 tasks x 16 cores = 74,000 sec run time.

I've yet to try dividing again but I have a feeling running 2 wu's will be best. Just a hunch. I'll test with the 3900X

Who has only ever used their own computers?


Me!
I'm just a family guy, at home with my own pc's. That's why I pay little attention to my rank with these "challenges". It's not apples vs apples and the results are usually the same.

I find it a bit of shame that cloud based stats are lumped in with people like myself.... but I guess it's hard to distinguish. (Cloud, vs a university, vs business computers, vs school, vs personal pc ownership etc)

BOINC is just one of those hobbies...... those with the deepest pockets win. Whether it be hardware or running costs. :)

Nice 3090 there Nick!
I was surprised to see the lack of 1st it's was getting but I'm sure there's a good reason for that.
I got 84% 1st with a 1660 super, so a 3090 should be abve 90%?


LOL... a 1660 is faster than my Radeon VII :D
