Query: Alpaka - An Abstraction Library for Parallel Kernel Acceleration   Porting applications to new hardware or programming models is a tedious and
error prone process. Every help that eases these burdens is saving developer
time that can then be invested into the advancement of the application itself
instead of preserving the status-quo on a new platform.
  The Alpaka library defines and implements an abstract hierarchical redundant
parallelism model. The model exploits parallelism and memory hierarchies on a
node at all levels available in current hardware. By doing so, it allows to
achieve platform and performance portability across various types of
accelerators by ignoring specific unsupported levels and utilizing only the
ones supported on a specific accelerator. All hardware types (multi- and
many-core CPUs, GPUs and other accelerators) are supported for and can be
programmed in the same way. The Alpaka C++ template interface allows for
straightforward extension of the library to support other accelerators and
specialization of its internals for optimization.
  Running Alpaka applications on a new (and supported) platform requires the
change of only one source code line instead of a lot of \#ifdefs.
