Hi,
I installed both CAL and Brook+. When I want to run any sample app, I get the message "amdcalrt.dll missing". I searched my whole hard disks for that file, but didn't find it, nowhere
Where do I get this file from?
I also tried 'repairing' the SDK installation, but this didn't help.
Thanks in advance!
Ok I checked the version I downloaded. It was 6.11.
There seems not to be any better version.
I have a Radeon 9250. Maybe there isn't a better version for that junk card.
In an other PC I have an X1650 Pro.
Will it work with this one?
Thanks!
Ok thanks but tell me why won't I get 'hardware acceleration' with an X1650 Pro? I bought the computer with this card 22 month ago, that's not THAT a long time. I'm sorry, but when even my existing X1650 Pro isn't supported, why should I still buy ATI cards? There's a competitor of ATI (I won't tell the name here ) which has CUDA, which is (at the current time) much better than ATI Stream I think. Sorry, ATI
Do you see? Even their forum doesn't work right (you should have seen this message before I re-posted it to get it right)

1.3 too supports CPU backend and can be used if you set BRT_RUNTIME=cpu or selected automatically if runtime is failed to initialize CAL backend.
Ok, I don't want to prefer nVidia or ATI, I think it's good when there's competition, this increases the general product quality and decreases the price for the end-user.
But somehow Brook+ and CAL don't convince me that much
Somehow this looks like a big hack to me - quickly released to avoid that nVidia spreads.
Somehow CUDA (and also the nVidia website) looks more planned and well-deviced to me.
One advantage of ATI is the much lower price.
You know, I'm new to GPU computing. But here in the ATI Stream forum I read this:
>>>
Brook 1.3 does not support multple gather streams
so that is illegal to write:
------------------
kernel void multiscatter(double input<>, out double output1[], out double output2[])
{
int index = 33;
output1[index] = input * 2.0;
output2[index] = input * 3.0;
}
-----------------
Unfortunately, this can be quite common requiring the programmer
to split the code above into multiple kernels and doing
duplicate work.
<<<
Ok, so I have to do the duplicate work. What am I doing this whole GPU stuff for? To get my app faster. And then, because of lacking software features I must do the duplicate work with ATI Stream.
Not that great
Ok thanks for the help. But allow me two questions, please answer them directly:
-are you staff from ATI?
-what is better, ATI Stream or nVidia CUDA?
I'm mean, I know
Happy new year!
Aha. But in the nVidia forum there was a guy that said he didn't like Brook+ any more when he tried out CUDA. Here's the quote what he said:
>>>
Yes, this is the Stanford implementation of Brook, a C-language extension for data-parallel calculations. The original Stanford compiler (called BrookGPU) generated code which used OpenGL/DirectX calls and shader languages to control the GPU, rather than a more direct layer, like PTX or CAL. BrookGPU was a great environment, but the implementation was limited by the capabilities of graphics cards at the time. There is nothing like shared memory, scatter/gather operations are very awkward, and you have to use vector-operations to get maximum performance.
If you are stuck with some older cards (not sure if the Radeon 9 is too old) and feel like experimenting, you might want to play with the original BrookGPU to get an appreciation for how revolutionary the GeForce 8 and CUDA were. (or not, you could just take our word for it...) I programmed in BrookGPU for a few weeks, then the 8800 GTX and CUDA came out, and I never looked back.
<<<
But I just checked the prices. nVidia GTX260: ~270€, ATI Radeon 4870: ~220€. I don't know exactly which one is faster, but I think they are comparable. Hmm I don't know, I must buy a new card anyway. Now I face the decision ATI or nVidia.
No idea. What do you think?
Happy coding and again a happy new year (here there are only 5 hours left of 2008...)
Install 1.3 Brook+ and 1.2.1 CAL.
That's strange. Is this after setting BRT_RUNTIME=cpu?
I'm using a 4870.
Yesterday I installed Catalyst 9.2 (9-2_xp32_dd_ccc_wdm_enu_75974.exe) and I got an error for missing amdcalcl.dll and it was really not I stalled (I searched the whole hard disk).
Now I installed 8.12 (the seperate package version) and everything works fine. Have I downloaded the wrong 9.2 Version?
It's just a library renaming issue.
Don't worry, they're already aware and it will be fixed in SDK 1.4.
