With the US Department of Energy’s announcement of plans to base two future flagship supercomputers on
|
|
|
|
|
|
IBM POWER CPUs, NVIDIA GPUs, NVIDIA NVLink interconnect, and Mellanox high-speed networking,
|
|
|
|
|
|
many developers are getting started building GPU-accelerated applications that run on IBM POWER processors.
|
|
|
|
|
|
The good news is that porting existing applications to this platform is easy.
|
|
|
|
|
|
In fact, smooth sailing is already being reported by software development leaders such as

|
Erik Lindahl, Professor of Biophysics at the Science for Life Laboratory, Stockholm University & KTH,
|
|
|
|
|
|
developer of the GROMACS molecular dynamics package:

_The combination of POWER8 CPUs & NVIDIA Tesla accelerators is amazing.
|
|
|
|
|
|
It is the highest performance we have ever seen in individual cores,
|
|
|
|
|
|
and the close integration with accelerators is outstanding for heterogeneous parallelization.
|
|
|
|
|
|
Thanks to the little endian chip and standard CUDA environment it took us less than 24 hours to port and accelerate GROMACS._
