Key kernels of high-order discretizations and communications towards exascale applications


This talk will discuss optimal implementations of key kernels for high-order discretizations that will deliver high accuracy at low cost and facilitate efficient numerical simulations for a broad range of applications on future high-performance computing platforms. Test problems will include spectral element discretizations of the positive definite Helmholtz equation and their fast tensor-product evaluations of the inner products using the Gauss-Lobatto-Legendre bases and Gauss-Lobatto quadrature. General communication kernels for the gather-scatter operations between neighboring elements will be also discussed, and their performance analysis and scalability on recent multi-core and accelerator architectures will be demonstrated.
