Solving the Cardiac Model Using Multi-core CPU and Many Integrated Cores (MIC)

Simulation of the cardiac model through mathematical methods is a computationally demanding task, due to its higher spatial and temporary resolution requirements. Adopting the hybrid CPU and MIC programming platform may meet these requirements, since the brand new KNC provides higher computational power. We explored the hybrid CPU and MIC computational model based on a chosen PDE-ODE Solver. First, we adopt the parallel strategies including OpenMP, AVX, memory align to our experimental case on the CPU. Then we complete offload mode on our hybrid platform and acquired a speedup of 24. In the end, we complete the COI mode aiming to overcome the startup overhead of offload mode and acquired the computational performance of 61.11 DP Gflops on our CPU with single MIC platform and the speedup has reached 24.5.
