Hi, Matthew

Thanks, I have gotten it and I am studying it.

hi, everybody, I am translating English to Chinese.

http://en.wikipedia.org/wiki/MilkyWay@Home

The following text comes from wikipedia:

Using data from the Sloan Digital Sky Survey, MilkyWay@home divides starfields into wedges of about 2.5 deg. width and applies self-optimizing probabilistic separation techniques (i.e., evolutionary algorithms) to extract the optimized tidal streams. The program then attempts to create a new, uniformly dense wedge of stars from the input wedge by removing streams of data. Each stream removed is characterized by 6 parameters: percent of stars in the stream; the angular position in the stripe; the three spatial components (two angles, plus radial distance from Earth) defining the removed cylinder; and a measure of width. For each search, the server application keeps track of a population of individual stars, each of which is attached to a possible model of the Milky Way.


I can do it accuratly because I have no knowledge about this.

please show me some illustrations of the process.

best regard

First, the item "errers" was marked "Too many success results". But you cannot see anyone getting 1 credit.

Then, pay attention to computer 58276. Its runtime is zero and CPU time is 195,482.46 !?

What happen?

Hi, John Clark

well, that seems I have to downgrade Catalyst to 8.12 :-(

I hope it would not hinder CC......

But I insist my point that there is a bug in ati2dvag.sys! Because XP reports 'The device driver got stuck in an infinite loop.', when WMs were scheduled by BOINC. However, if I suspend all WUs of WM, then resume one after the previous WU was completed, thus the question was finally settled!

That's why I said 4850 cannot run WUs of WM continuously!

I hope Ati/AMD's driver coder could pay attention to this problem.

well, I got the file name is 'ati2dvag.dll' !

I hope this message can assist coders to hunt the BUG ! Beat it !

Thanks for your work.

Best Regart!

you have to use the AMD version of the app.

not the ATI named one.

HTH

Bill


I have rename the ATI files to AMD files.

Hi, Bill

Thanks for your message :)

....

But if I resumed a WU after the previous WU was completed, they will be done ?!

....


That means :

1. 4850 drived by catalyst 9.x can work.
2. It cannot run continuously except I launch the WUs manually one by one.

Why ?????

:(

Every time, When I resumed MW, I can and only can finish a WU. And then, the video card driver broke down after BOINC 6.10.11

launched the next one WU of MW ! At this time, Windows XP + SP3 turned the screen to blue background and said system was

ruined by Ati2*.sys (sorry, I forgot the file name). But if I resumed a WU after the previous WU was completed, they will be

done ?!

The program ati 2.0b - SSE2 runs on 4850 drived by 9.4 / 9.10 beta with PSU 400 !
This same environment running Collatz C (following call CC) is perfect !

Compred to CC, I ensure my system including software & hardware is ok ! What's going wrong ?

Thx !

When MW will relased CUDA app, all will be clear, We will be able to do direct comparision ATI vs Nvidia....

However, making cuda app takes sooooooooooooooooooooo long.....


I attached MW_gpu 3 mouths ago. I have ever recieved any CUDA WU. And now My account of MW_gpu has been deleted by server. It denied my login and refuse to accept I reattach it.......

I think CUDA is an impossible mission for MW_gpu......

It will come soon, some day, some month, some year. Only Travis knows. But there are enough CUDA projects like Seti/Seti beta, GPUGrid, Aqua !


I have no interesting in SETI.

GPUGrid doesn't like my 9600GT has only 64 SPs. It comments >= 96 SPs.

Aqua's CUDA WUs have run out!

I have never receive CUDA WUs since I join Milkyway_GPU in May 24, 2009.

It always say "Server error: feeder not running".

I have a 9600GT card. But I have never received GPU WU!

Why and how to get GPU WU ?
