By the way, I have a Polish name, but neither I, my parents nor my grandparents speak/spoke it.

Physik is a Polish name? :)

I'm running HD3850's in two boxes right now, for an avg. of 20K WUPD.

At USD 59.99, or ~ GBP 37.00, this thing is a steal: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102794

Can anyone tell me how i can see if my card is being found by mw or boinc
I have 2 x 4770 ati cards but they are only be able to install with cat 9.4 or 9.5

Look at the Task Details for a completed WU done by your box with the 4770's. Here is one for my Q6600 with a HD3850:

12) Message boards : Number crunching : MW power outages (Message 22725)
Posted 19 May 2009 by Profile caferace
Post:
From the front page, in case you missed it:

Power Outages (Continued)
May 19, 2009

Looks like the power is going to be out until tomorrow morning with another outage tomorrow afternoon. I'll post more information as we know about it.

Another Power Outage
May 19, 2009

There's another power outage today at 4PM EST, which will bring the server down again. I'll try to get it up and running right after the power comes back.

Back up and running
May 18, 2009

The reason we went down today a few times was that there were power outages on campus while they were doing things to the electrical system. Hopefully things should be up and running smoothly now.

So, down in one hour, back up again sometime 12-16 hours or so...

It only means that much more science is getting done that much faster.

Science and politics mix poorly.

16) Message boards : Number crunching : Why does MW scan a random port with each server contact? (Message 21679)
Posted 9 May 2009 by Profile caferace
Post:
It appears that the mystery packets are coming in "new not syn", which is said most likely to be caused by a broken TCP implementation. They are all part of the exchange with the server but for some reason come in with no sync bit. I doesn't seem to cause any stutters in the overall transaction, I can upload, report, and if there's work available, download it. I read a couple articles that claimed that MS IIS strayed from accepted TCP protocols and use the 'new not' syn' scenario as some sort of speed up mechanism for it's servers.

FWIW, Milkyway is running Apache. Yay. :)

But now it's Friday evening, the Cubs are on, as is my low alcohol light. So I officially make this a "tomorrow problem". :)

Hmm. Not a baseball fan, but a refreshing beverage sounds like a fine idea.

I'll be done with my part hopefully tonight or tomorrow. Then it's up to Travis to get the apps up. I'm not sure if he's done with them yet but hopefully they're ready for alpha testing.

Dave, I think part of the reason people are curious is because of the new "no jobs available" messages we're getting right now.
