Hi ya’ll,

I’m a bit new to this CUDA thing. I’m trying to use atomicXor, but it doesn’t seem to be working. The error that it’s giving me is : error: identifier “atomicXor” is undefined >.< . Does this mean that it’s just not on my device (Nvidia 9800 GT2)? If anyone can toss me a hint I’d really appreciate it!

Compile with -arch sm_11
