Investigating half precision arithmetic to accelerate dense linear system solvers

The use of low-precision arithmetic in mixed-precision computing methods has been a powerful tool to accelerate numerous scientific computing applications. Artificial intelligence (AI) in particular has pushed this to current extremes, making use of half-precision floating-point arithmetic (FP16) in approaches based on neural networks. The appeal of FP16 is in the high performance that can be achieved using it on today's powerful manycore GPU...
