Query: kEDM: A Performance-portable Implementation of Empirical Dynamic
  Modeling using Kokkos   Empirical Dynamic Modeling (EDM) is a state-of-the-art non-linear time-series
analysis framework. Despite its wide applicability, EDM was not scalable to
large datasets due to its expensive computational cost. To overcome this
obstacle, researchers have attempted and succeeded in accelerating EDM from
both algorithmic and implementational aspects. In previous work, we developed a
massively parallel implementation of EDM targeting HPC systems (mpEDM).
However, mpEDM maintains different backends for different architectures. This
design becomes a burden in the increasingly diversifying HPC systems, when
porting to new hardware. In this paper, we design and develop a
performance-portable implementation of EDM based on the Kokkos performance
portability framework (kEDM), which runs on both CPUs and GPUs while based on a
single codebase. Furthermore, we optimize individual kernels specifically for
EDM computation, and use real-world datasets to demonstrate up to $5.5\times$
speedup compared to mpEDM in convergent cross mapping computation.
