A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users.


I seriously doubt any Milkyway users are planning this.

Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways...


Nothing the like in here but free credits...

One common method of attack involves saturating the target (victim) machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.


Only the top 150 users gets decent credits.
Out of 49,310 hosts (computers) only 17,332 are active and only a fraction of those could or could not run scripts

While a typical web server can handle a few hundred connections/sec before performance begins to degrade, most web servers fail almost instantly under five or six thousand connections/sec. With a moderately big peer-to-peer attack a site could potentially be hit with up to 750,000 connections in a short order.


We are extremely far from this. So MW is not, never was and may never be under DOS attack from it's very own users.

With the clearing out of AP v5.03 are we perchance going to v5.05? Just a question.


Well it seem now SETI@HOME is facing some lack of work for Astro Pulse.
I haven't had an AP in 3 weeks.
All we are getting is resends.
Server has been dry of AP in like a month now.

For breakfast I love toast with butter and mustard on it with a giant glass of milk.
The strangest thing I have eaten would have to be austrich and crocodile jerky.

I have mixed emotions about this but I have to agree with Ice.


So what about ATI cards? Is it a mistake to buy one now? I can't say, I'm unlikely to buy any more, my buying contribution there is done.


Same here! My contribution, monetary speaking, is now done for the moment that is and will just wait what the future months bring.
For now I have a 4870 downstairs that has done as much work in a month, than it took my 2 computers to do in 1 year.

Having 2 gaming system and having been a "NVIDIA" guy all my life the decision to purchase a 4870 was based on both the gaming power and the crunching ability of this specific card.

And a GTX285 upstairs. So right now I am covered on the 2 different routes whether ATI or GPU will win the crunching battle.
My GTX285 was purchased for my gaming addiction at 1st shooter games and RPG's like Far Cry2 and Half Life and so on.

I had a 8600GT in the downstairs computer so it was time to make a decision and I chose to spend the money for a 4870.

Having said all that, I also admit it is gratifying in knowing one can contribute so much credit in so little time and the credit versus power consumption is well worth it.

Heck, it took me 2 year to get to 11 000 credit when I first started crunching for SETI with my now defunct Celeron. Needless to say the credit versus power consumption then was just abhorrent.

But science tends to go in one direction only and that is upward.
I wish it would be the same for my investment...

I think those who have spend money for whatever hardware should be rewarded as far as crunching/credits. In the same token let's not forget the ones who simply cannot afford better hardware and can only hope that an app will help them also.
Not too long ago I for one who could not afford a dime. But time changes.
Would I wish to have a farm of computers? Heck yeah. But this is simply not an option for me.

It says on the front page of MW@home that there would be a massive update today about MW GPU.
Where does this update would originate from? California or somewhere in the UK?
If from the UK that means it is already evening there. I am in Central Canada.
That would make UK to be about 8-9 pm right now.

Post:
Yes. You'r quite correct.
I would imagine at least $6000 for barebone kit up to .......
But like you said the pricing changed quite a bit in the last year.

I will stick to my Q9550 for now.

Look at this desktop personal supercomputer Here
4 cards is the max for today's MOBO. So far as I can see. The MOBO will have to be quite extended to accomodate 7 Cards the way they make them today.

No wonder you have to phone them guys for a pricing...
Must be quite the $.

Hahaha!
That was cool.
Now let's get ready for an avalanche of post....

1.4 million.....
One would only dream to achieve this (me)
But not with 2 computers.
Heh!! I am still happy to crunch whatever comes my way..

Blah!
Ignore the below comment.
I meant S@H Beta NOT MWGPU.
Wrong forum. Wrong Thread!
Too many forum reading = Brain confusion.

I tell you what.
Those MWGPU WU are really slowing my computer to a crawl..
Seem I get stuck with all the VLAR...
Aw well in the name of science.!!!
@ Misfit you said you "purged" thoose from your system and will not get anymore?
Is there a script to avoid getting those??

Any new news anyone about how MW GPU is developing?
Did Travis inadvertently created a Black Hole in which he got sucked in and disapeared from the surface of the earth?

The GTX285 gives you the most bang for the buck.
Allthough I have a Q9550 and GTX285 I find it becomes choppy when both cpu and gpu are crunching at the same time while I use the computer. I did set BOINC to stop gpu while computer is in use but all the family uses it constantly.
So for now I just use the cpu side of it to do AP and will undertake the gpu when MW gpu will be set and running.
In my region (Regina, Saskatchewan, Canada) there was a $300 difference between the GTX285 and the GTX295 so I opted for the GTX285 which is plenty for my gaming and any other everyday use.
Gpu is only a great addition to this system but I don't use it quite much as of yet.
