Performance analysis of using GPU computing in MATLAB to simulate electromagnetic fields generated by current carrying wire

摘要

This paper documents a performance analysis of using CUDA in MATLAB to simulate the magnetic field generated by current running through a wire using the Biot-Savart law. It was found that the number of threads executing in a CUDA kernel varies the execution time linearly and the number of threads per block should be set to a power of 2 to optimize performance during runtime.
