@ -124,9 +124,8 @@ multiple threads can be launched by each MPI task running on a CPU.
To build with Kokkos support for NVIDIA GPUs, NVIDIA Cuda software
version 6.5 or later must be installed on your system. See the
discussion for the :doc:`USER-CUDA <accelerate_cuda>` and
:doc:`GPU <accelerate_gpu>` packages for details of how to check and do
this.

@ -393,8 +392,8 @@ Generally speaking, the following rules of thumb apply:
* When running on CPUs only, with multiple threads per MPI task,
performance of a KOKKOS style is a bit slower than the USER-OMP
package.
* When running on GPUs, KOKKOS is typically faster than the USER-CUDA
and GPU packages.
* When running large number of atoms per GPU, KOKKOS is typically faster
than the GPU package.
* When running on Intel Xeon Phi, KOKKOS is not as fast as
the USER-INTEL package, which is optimized for that hardware.
