hi all..

If i have code which runs well standalone with CUDA, and i want to run it at comparable speeds from within Houdini, are there any reasons why i might want to consider running it with VEX if porting is less important than raw speed? It seems like a straightforward question, but i'm wondering whether there are any hidden costs to data marshalling and the like which might favor VEX.

I'm being lazy i guess.. on the off-chance that maybe there is something that isn't obvious.

thanks

There is at least one limitation. If you are using Amazon EC2 via HQueue you cannot currently use a GPU setup (or HDK nodes) without further work from Amazon. Neither of their standard racks currently support GPUs.
