Room: Amphithéatre S113 The IEEE 754-2008 standard recommends correctly rounding elementary functions. However, these functions are transcendental and their results can only be approximated with error epsilon >0. If o_p is a rounding function at precision p , there may exist some arguments x, called (p,epsilon) hard-to-round arguments, such that o_p(f(x)−epsilon) be distinct of o_p(f(x)+epsilon), inducing an uncertainty on the rounding of f(x). Finding an error epsilon such that there are no (p,epsilon) hard-to-round arguments is known as the Table Maker’s Dilemma (TMD).

Room: Amphithéatre S113 OpenHMPP (HMPP for Hybrid Multicore Parallel Programming) - programming standard for Heterogeneous computing. Based on a set of compiler directives, standard is a programming model designed to handle hardware accelerators without the complexity associated with GPU programming. The OpenACC Application Program Interface describes a collection of compiler directives to specify loops and regions of code in standard C, C++ and Fortran to be offloaded from a host CPU to an attached accelerator. OpenACC is designed for portability across operating systems, host CPUs, and a wide range of accelerators, including APUs, GPUs, and many-core coprocessors.
