Cannot load .cubin module in CUDA Driver API

I am using 0.3.1 JCuda and 3.1 nvidia cuda sdk. I am trying to run JCudaRuntimeDriverMixSample.java from here. I compiled the .cu file with "nvcc -keep invertVectorElements.cu". I set the cuModuleLoad filename to the .sm_10.cubin file generated. When I run the compiled java file, I get CUDA_ERROR_INVALID_SOURCE. I am running nvidia driver version 256.53 on a GTS 450 gpu.

Have you tried loading the .ptx file rather than the .cubin file? As I understand it, .cubin files are already assembled for very particular architectures, whereas .ptx are JIT-compiled by the driver. (You can still use cuModuleLoad with .ptx). You're attempting to load the sm_10 version of the cubin - but do you have a compute capability 1.0 device?
