- we were not 16-byte aligning cuDoubleComplex variables. error showed up "much later" in cuGetVector (error 11) and cudaDeviceSynchronize (error 4). Did binary search to find source of error. How do we program so that errors show up "immediately"? cuda_safe_call?
- if we have 1 number used by many threads should it go into shared memory? constant memory? we would think constant memory would be the right answer. shared memory would give a bank conflict.
- cuda-gdb generates output for kernel launches. slows down the code dramatically? becomes unusable.
