I got a problem with a fluid dynamics application programmed in c++ and cuda.
It works on my new computer, with SDK 5.0 and a CUDA Capability Card of 2.1 (Nvidia GT610).
Unfortunately i also have to run it on a CUDA Capability Card of 1.1 card, a Nvidia Quadro FX 570. And it seems not to work on the old hardware. Does anybody have an idea, why the exacly (!) unchanged cuda kernels doesnt work any more on the older FX570??? SDK is also 5.0 on the old computer, VS MS 2010 is on both computers the IDE.
“Not working” means that the kernels seem not to be active, because my data has not changed. On each computer i compile to debug mode and 32bit. On the new computer, everythings works just fine and as expected.
