Figure 2 shows the computation time on 32 cores of various matrix multi- multi-plications: the numerical dgemm implementation of Plasma-Quark, the  imple-mentation of pfgemm of fflas-ffpack using OpenMP tasks, linked against the libkomp library
Table 1 sketches the different shapes of the associated routine calls in the main loop of each variant.

This paper presents a novel technique for reduction of a process model based on the notion of in- dication, by which, the occurrence of an event in the model reveals the occurrence

We then recall that isotropy does not uniquely determine the distribution of a sample on the sphere and show that the convergence rate in isotropic algorithms is improved by

The general approach chosen here, contrary to the way half-integral weight modular forms are implemented in Magma [BCP97] and Pari/GP [The19] (the latter has more features, such

We investigate certain finiteness questions that arise naturally when studying approximations modulo prime powers of p-adic Galois representations coming from modular forms.. We

For N = 5, 6 and 7, using the classification of perfect quadratic forms, we compute the homology of the Voronoï cell complexes attached to the modular groups SL N ( Z ) and GL N ( Z
