This PostDoc will be carried out in the framework of the PEPR NumPEx project devoted to High Performance Numerics for the Exascale.
Nowadays, most numerical simulations are performed in IEEE 754 binary64 precision (double precision). But this approach can be costly in terms of computing time, memory transfer and energy consumption. Precision autotuning makes it possible to optimize the numerical types in a program. The PROMISE software (http://promise.lip6.fr) provides a mixed precision version of a program by taking into account the requested accuracy on the results. During this PostDoc, several directions will be explored to improve algorithms for precision auto-tuning and numerical validation. A complete description is given in the associated file.
