BOBA: A Parallel Lightweight Graph Reordering Algorithm with Heavyweight Implications

Autor: Drescher, Matthew, Awad, Muhammad A., Porumbescu, Serban D., Owens, John D.

We describe a simple parallel-friendly lightweight graph reordering algorithm for COO graphs (edge lists). Our ``Batched Order By Attachment'' (BOBA) algorithm is linear in the number of edges in terms of reads and linear in the number of vertices fo

Essentials of Parallel Graph Analytics

Autor: Osama, Muhammad, Porumbescu, Serban D., Owens, John D.

We identify the graph data structure, frontiers, operators, an iterative loop structure, and convergence conditions as essential components of graph analytics systems based on the native-graph approach. Using these essential components, we propose an

Better GPU Hash Tables

Autor: Awad, Muhammad A., Ashkiani, Saman, Porumbescu, Serban D., Farach-Colton, Martín, Owens, John D.

We revisit the problem of building static hash tables on the GPU and design and build three bucketed hash tables that use different probing schemes. Our implementations are lock-free and offer efficient memory access patterns; thus, only the probing

Planar N=4 gauge theory and the Inozemtsev long range spin chain

Autor: Serban, D., Staudacher, M.

Publikováno v: JHEP 0406 (2004) 001

We investigate whether the (planar, two complex scalar) dilatation operator of N=4 gauge theory can be, perturbatively and, perhaps, non-perturbatively, described by an integrable long range spin chain with elliptic exchange interaction. Such a chain
