Fix cudaErrorNotSupported: Feature Not Available

Overview

cudaErrorNotSupported indicates attempting to use a feature not available on the current GPU or driver.

Error Messages

CUDA error: not supported
cudaErrorNotSupported

Common Causes

• •Feature needs newer GPU
• •Driver too old
• •Feature disabled
• •Compute capability too low

Solutions

cudaDeviceProp prop;
cudaGetDeviceProperties(&prop, 0);
printf("Compute: %d.%d\n", prop.major, prop.minor);
printf("Cooperative launch: %d\n", prop.cooperativeLaunch);

if (prop.cooperativeLaunch) {
    useCooperativeKernel();
} else {
    useFallbackKernel();
}

Prevention Tips

• ✓Check capabilities at startup
• ✓Implement fallbacks
• ✓Document requirements

Code Examples

Before (Problematic)

No capability check.

cudaLaunchCooperativeKernel(...);  // May not be supported

After (Fixed)

Check first.

if (prop.cooperativeLaunch) {
    cudaLaunchCooperativeKernel(...);
}
