Xeon Phi, based on the Intel Many Integrated Core (MIC) architecture, packs up to 1TFLOPs of performance on a single chip while providing x86__64 compatibility. On the other hand, InfiniBand is one of the most popular choices of interconnect for supercomputing systems. The software stack on Xeon Phi allows processes to directly access an InfiniBand HCA on… (More)
A ÿnite graph is said to be locally-quasiprimitive relative to a subgroup G of automorphisms if, for all vertices , the stabiliser in G of is quasiprimitive on the set of vertices adjacent to. (A permutation group is said to be quasiprimitive if all of its non-trivial normal subgroups are transitive.) The graph theoretic condition of local quasiprimitivity… (More)
We discuss the enumeration of function fields and number fields by discriminant. We show that Malle's conjectures agree with heuristics arising naturally from geometric computations on Hurwitz schemes. These heuristics also suggest further questions in the number field setting.
