The floating point speed of

The floating point speed of the whole project is going down.... Now is the lowest in 8 weeks and sinking fast. I am worried that it means that a lot of people is quitting the project. I suggest that it will be wise for the developers to say something before it becomes a permanent trend... I think if they talk honestly people will understand and collaborate on a beta test, or at least come back a week or two later, when everything will be working right.

Maybe it's going down because computers aren't connecting as much since the work units are so big?

I mean, my computers used to connect daily for work. Now, some go several days without needing to connect.

And I'm desperately trying to make my Debian cooperate with the cheap trashy modem my new ISP provided... as that host is an AMD, I'd really prefer running Linux, but it simply won't let me go online and get BOINC and a few WUs...


Well, if it's an option for you and you have 256kB memory left, you could just run Windows and install VMWare Player, like I did. You could do a small Linux installation, get 35% more credits and 35% more benefit for the science. :-)
And the best, if one knows how to do it, it takes just about an hour.

If you like to do so and you have any questions, then come over to our team forum - it's a lot easier for me to write in my mother language. ;-)

What hardware platform are you running on? IIRC someone else tested on his dualboot and only found a few % difference between windows and his linux distro.

I run dual boot, but for work I mostly need Windows(XP pro).
Win on AMD loses about 40% and more with the new app.
So I run 2 instances of VMWare player on my X2. I have also looked up a couple of host to verify this.

Like I already wrote in this thread I got the following results:
Host is an AMD X2 4400+@2,63 GHz

Os Win XP pro:
old app: 23.12 credits/h
new app: 14.11 credits/h !!!

Guest: OpenSuSE VM 1,2:
new app: 21,72 and 21,75 credits/h :-)

I have to add that my router,

I have to add that my router, a Celeron 433 ist much faster with th new app:

old: 1.49 cr/h
new: 2.82 cr/h (extrapolation)

:-))

This clearly proves, that there is no SSE used in the new app.

Whoa. Definately going to have to setup some VMs myself at some point in the near future.

Not really. All it proves is that the margin between the two is much narrower. IIRC one of the changes made for this build was that the compiler was set with autovectorization turned on which generates SSE code without the developer having to do as much setup work in advance. Since the einstien apps have been designed to automatically switch between x87 and SSE code depending on CPU capabilities you'd need to actually decomile the app to see if it does or doesn't.

I have Rosetta already loaded, and if the AMD is an inferior CPU running E@H THAN I"LL JUST SWITCH

Now now... Don't want to be a CW... ;-)

As an aside, has anyone tried out Virtual PC 2007?
