I have downloaded and installed the stream sdk v1.2.0,

i've checked that all enviroment paths, as mentioned in the FAQ on this forum,  are set, same goes for VS settings. I have no problem compilling, but when I run one of the samples I get the follwing error:

Unable to initialize CAL runtime, falling back to CPU

i'm running on Win XP(32bit) SP3 with catalyst 8.9 on HD4870 1GB

what to do?

Hi,

   can you be precise, like in which sample you got that problem?

GAYAM.

it get this in all the brook+ samples i've tried to run. I've tried the binary search sample to name one.

I had a similar problem, I installed 1.2 patch for WinXP 64 bit in the main page (contains both 32 and 64 bit versions) and changed paths to 32 bit directories.

thanks a bunch, only now when I run any brook+ sample like simple_matmult or binary_search. I get a Unhandled exception at 0x00597f54 in simple_matmult_d.exe: 0xC0000005: Access violation writing location 0x00000040. on runtime

by attaching a debugger i found out it happens as soon as the programs calls the streamRead() function

any ideas ?

I have the same problem, and my GPU is 4850HD, the Catalyst 8.8, xp SP2, 32bit.

What can I do?

The "Unable to initialize CAL runtime, falling back to CPU" error usual suspects are:

- Do not use Windows Remote Desktop connection

- Do not run UltraVnc with Video Hook Driver turned on

- If using XP64, use the 1.2 patch as given in the forum

- In Linux, make sure X-windows is running.

- Check the driver installation. CAL will definitely not work if driver is not installed properly.
