- Abstract:
- We discuss some performance issues of the tiled Cholesky factorization on non-uniform memory access-time (NUMA) shared memory machines. We show how to optimize thread and data placement in order to improve performance. The final result is 50\% faster than PLASMA and 75\% faster than MKL.
