app does not execute properly on FW 256.96 but yes on 197.45

Hello,

I have an app that works perfectly using the FW 197 but with the new FW 258 simply returns me zero values.
The FW 258 are the problem, the app runs ok with other drivers or even with ATI cards.
Ten different programmers have revised the code and we simply cannot find an explanation for that behavior. No error or exception is neither thrown.
We truly think is a bug in your JIT compiler.

Where can I submit a link to the app for testing & conformance, pls? Cannot provide the source code, just the executable.
thx

Read through the forum and you’ll see that many things are broken in the new drivers. For example, constant memory does not work. That in itself could be the cause for getting zero output, as constant memory references within the kernel return zero.

I definitely use constant memory, so it’s possible, yep.
