Been a slow week for me - and most of the team with a massive ppd
drop off over the weekend. Lots of red on the table this week :(

Welcome to both JHeaton and Cruize, both entering the ppd ranks mid table.

You may notice a small cull in the stats this week, with member with zero output being removed from the graphs. (but the table will always inc. the full 29 members)
Biffa and Colasanto both making a single days output and makeing the cut
by the skin of their teeth - *cough* stats junkies *cough* :p

WA high-tech business helps astronomers discover the Universe
A quest to study the earliest stars and galaxies in the Universe is underway, with Australia's local industry building the first major pieces of a
revolutionary new radio telescope in Western Australia, as part of the Murchison Wide-field Array.Murchison Wide-field Array (MWA) industry
partner and Fremantle-based high-technology company, Poseidon Scientific Instruments (PSI), has been awarded a $1.3m contract by Curtin
University to build 16 packages of sensitive electronics, using a smart design suited to the environmental and radio-quiet conditions of outback WA.

The MWA is being built by an Australian consortium led by The International Centre for Radio Astronomy Research (ICRAR), a joint venture
between Curtin University and The University of Western Australia, in close collaboration with US, Indian and New Zealand partners.

The MWA is located at the Murchison Radio-Astronomy Observatory, a site operated by CSIRO and a proposed core site for the multi-billion dollar
Square Kilometre Array (SKA).

The MWA will be the first of three official SKA precursor telescopes to be completed, proving the technology and science on the path to the SKA.
Australia and New Zealand are bidding to host the SKA, with the site location to be decided in February 2012.

There's a broken image under 'worldwide alliances' :(


Thanks for the news. Been a horrendous week for me as crunchers just don't want to keep running. :(

Borged a dual-quad xeon overnight. I figure it'll make up a fair whack of my output on its own. :D
 
Thanks for the news :)

There seems to have been a lot of downtime this week :( I have also had to reduce the number of windows I have open as I was seeing about a 15% increase in WU times on milkyway with this running on all cores.
 
Hi guys,
I just joined this project with my family's Athlon quad but it only seems to be using a max of 25% of the CPU, i.e. one core.
Is there a way to get it to use all 4 cores?

Are you only using the background app? That will only use one core, if you want to use all four cores you will have to open three browser apps as well.

I am, yes, annoying that it is limited to one core. Is there a way to use all 4 cores without using the browser client? If not I guess it can go back to folding on the other 3 cores.
 
That's fair enough, but it would be nice to have the option, like with F@H you can run 1 client, or multiple clients, or the SMP client to use all 4 cores.
No worries then, I'll leave one core to TheSkyNet and get it folding on the others rather than leave them doing nothing. Leaving the browser client open isn't really an option or I'd do that.
 
had lot's off can't connect brower windows this morning - and now have five clients running but only four windows.

tried closing them all down (nothing showing in task manager) open four new windows and five are active again - very odd
especially as dashboard say i have 3 running :D
 
just done the stats grab and we're all (berserker being the exception) about half our normal output.

The quote below if a reply to mine and other peoples posted issue.
The wait 5 mins if restarting mulipule browers it worth knowing

Hi All,

Sorry to hear you've been having issues connecting to theSkyNet. Rest assured I do keep an eye on the systems as much as possible, including weekends, but as I'm on GMT time this might not coincide with your daytime.

There were issues today with 1 server (we have 7) which I think explains your issues connecting. This is now fixed and all systems have been running as normal now for a good 2+ hours.

Another issue you should be aware of is that the clients limit themselves to a maximum of N= number of cores on the machine. Opening more than N results in clients which die after about 2 minutes. However, because of secuity restrictions the "live count" known to each client is obtained from their server and this can be a large number if you recently had some clients which were killed recently. The server does not know these clients are dead, and so reports to new clients that there are N others there - and so the new ones die almost immediately.

To be safe when running (or wanting to run) a lot of clients, don't expect more than N=number of cores to work, and if you find the need to terminate clients wait 5 minutes before loading them all up again.

Hope this helps

Rhys Newman
