Long-time simulations with complex code using multiple nodes of Intel Xeon Phi Knights Landing

作者：

Highlights：

•

• The Intel Xeon Phi Knights Landing is a many-core processor with 68 cores.

• Performance is studied for a complex application problem modeling waves in a heart cell.

• Performance using the on-chip memory is excellent for one as well as several Phis.

• Using the Intel Phi requires hybrid code with MPI and OpenMP for best performance.

• The performance of the many-core Intel Xeon Phi enables large-scale simulations.
