I am working on a machine with Ubuntu 9.04 x86_64 and an 8800 GTS 320mb.
I’ve been debugging my code by compiling it with -g and -deviceemu, then running regular old gdb on it. this has worked so far because I’ve gotten the same error messages in device-emu as when working with the gpu.
But now the GPU gives me an unspecified kernel launch while the device-emu works fine.
What would you do in this situation to debug?
I think the errors are NaN related but thats not easy to find the source in a 2000 line code.
