Niketan Pansare closed SYSTEMML-1152.
-------------------------------------
       Resolution: Won't Fix
    Fix Version/s: SystemML 1.0

Hi Nakul,

Since we anyways need to add custom kernels for other operations (such as rowsums, ...) and since corresponding kernels are already implemented, I would recommend not adding additional jcuda-vec dependency unless the current kernels are bottleneck.

Thanks,

Niketan.

> We should explore the use of [jcuda-vec|https://github.com/jcuda/jcuda-vec] to replace the set of custom kernels we write. The custom kernel already does a branch/switch-case on each invocation. This is probably not the most efficient thing we can do.
