Now then, a little fan and case optimizing and the beast is down to 78C GPU and 76C Mem (running 900/1000).

Just got my 4890 runnin' - the sapphire 900MHz version.
Loud, hot and seems fast... check here

What do you think - is 90C still ok?

[edit]
LOL - forgot to plug in one of the case fans...
85C now.

looks like the cpu is faster...

Or the GPU calculates quite a bit more ;)

CPU(intel core2 e6750) vs GPU(nv geforce 9600gt) computation times linux_x86_64 on stripe-20. Could you explain this?

CPU:
real 4m15.913s
user 4m6.327s
sys 0m0.800s

GPU:
real 15m45.243s
user 15m30.878s
sys 0m0.484s

about makefile
what the difference?
48: LINUX_LDFLAGS_i686 = -L/usr/X11R6/lib -L/usr/local/lib
53: LINUX_LDFLAGS_x86_64 = -L/usr/local/lib

OK, so even though I can run SSE3 apps on this chip running under WinXP, when I fired up the client running on Ubuntu 9.04 indeed it did not list SSE3 as a feature of my CPU, only SSE2. So now the question is, which app do I want?


open a root treminal, type
cat /proc/cpuinfo
and look if SSE3 will show up for the cpu.

The 0.18 mkII marked for Linux 32 bit or the 0.18d (older) marked for Linux 32/64 bit. I'm running the 64 bit OS so as far as I can see it's a choice between one of these two but I'm not sure which one.


I didn't make any 64bit SSE2 - assuming that any 64bit capable cpu is SSE3 capable.
BTW, mkII or not doesn't really matter.

The linux client is simply inefficient compared to win32.

I thought the fastest version of Speedimic is quite close.

Just looked it up, speedimics own Q9550 (45nm, 2.83GHz) is taking about 1030 seconds for a 27.77 credit WU under Linux.

He has another host (Q6600, 65nm, appears to be overclocked to 2.7-2.8GHz from the benchmark values) completing the same tasks in about 1150 seconds under Windows. It is a somehow bad comparison because of the different clockspeed and that the 45nm CPUs should be faster per clock than their 65nm counterparts, but nonetheless it is clear that his Linux version can't be that bad.


To be honest, the win-apps by ClusterPhysik are a bit faster.
Those Q6600ers aren't OC'd (the benchmark results might be a little off because of the 6.1 BOINC client)
If I recall it right, Cluster made some more modifications which didn't make it into stock code...

As stated before my apps are compiled from stock source and approved by Travis.

@mfl0p:
The compiler flag "-fp-model fast=2" doesn't make any difference - nighter in speed nor in accuracy (at least on my test box).

I'm not sure if we can do this having GPU milkyway as just a separate application or not.


Your plan sounds good and maybe the answer. One thing though, will you have any controls in place to avoid those using GPU's to only do those particular workunits? With the way things are now its a free-for-all trying to get work.

I guess what I am trying to say is that will your backend be able to tell that the client is running the GPU application and only send work appropriate as well as knowing that the CPU applications are requesting their work specific loads?
...


That's good question, as BOINC doesn't recognise ATI cards as coprocessors.
For the backend a ATI-gpu-cruched Wu must be looking like a cpu-crunched WU...

Just setting up a box for a friend - and could not resist to try his 4850. :))

Well, reading about it is definetly different to seeing it... this IS fast.

I gess I got to my one too. Any recommendations? I'm not looking for the fastest, more like "best bang for the buck"

yep, tried a comeback 2 weeks ago... half the wus didn't even dl and the forum looks like project staff has forgotten where it is...

Oh yea, I forgot to mention, 3 of the 6 images are animated (all made by me) - I'm working on the others :P


hmm... won't improve the situation for me. :(

I'll try to get another browser...


Goto 'Your Account', 'Community preferances' & check 'Hide signatures'.


no, I won't see the planes then. ;)

Just installed Opera mini - by far not as pretty and handy as Chrome - but I can read the posts.
Put in your sig whatever you like :P

As I previously mentioned, I got the zslip sites for an invention I had/have in mind, but turned over the sites to MilkyWay science (not the invention, just use of the sites). zsling initially was to get the most images/links in a BOINC project signature - I have 6 images and 5 links in my MilkyWay signature, which, as you know is restricted to 250 characters. Now, is that optimization or what :P

LOL, now I know why the browser of my G1 freaks out when it comes showing your posts. Must be that animated stuff...

Are you planning on offering the coproc information in the xml stats at all ?

Seti implemented a server-side change in the code to do this and gpugrid followed..

Allows the stats sites to display the information on the host pages like here

Bok


...or have separate stats for GPU like suggested here: Separated stats for CPUs and GPUs.
