Thanks! That's what I thought. Bah. I'll try to push this with them ... it really would be nice if it was a more flexible implementation anyway. Like logging ... it opens a .o and .e file for each kernel, which gets pretty ugly when launching 65 kernels over and over again. :)
Thanks again for the help, I'll make sure to credit all of you (I love reading this list, so useful) when they implement any changes.
