Indirection Stream Semantic Register Architecture for Efficient Sparse-Dense Linear Algebra
Sparse-dense linear algebra is crucial in many domains, but challenging to handle efficiently on CPUs, GPUs, and accelerators alike; multiplications with sparse formats like CSR and CSF require indirect memory lookups. In this work, we enhance a memory-streaming RISC-V ISA extension to accelerate sparse-dense products through streaming indirection. We present efficient dot, matrix-vector, and matrix-matrix product kernels using our hardware, enabling single-core FPU utilizations of up to 80% and speedups of up to 7.2x over an optimized baseline without extensions. A matrix-vector implementation on a multicore cluster is up to 5.8x faster and 2.7x more energy-efficient with our kernels than an optimized baseline. We propose further uses for our indirection hardware, such as scatter-gather operations and codebook decoding, and compare our work to state-of-the-art CPU, GPU, and accelerator approaches, measuring a 2.8x higher peak FP64 utilization in CSR matrix-vector multiplication than a GTX 1080 Ti GPU running a cuSPARSE kernel
Managing death
Drawing on provocative case studies, personal interviews, and detailed research, James Hoefler examines the medical, legal, ethical, and clinical aspects of right-to-die issues. Beginning with the legal struggle of a woman whose son existed in a persistent vegetative state (PVS) for seventeen years, the author moves into a broader look at consensus among professional organizations, from the AMA to the President's Commission to the National Center for State Courts; beliefs of mainstream religious groups; public opinion; issues surrounding end-stage Alzheimer's and other organic brain disorders that can slowly lead to PVS; and the role of artificial nutrition and hydration in these casesHoefler concludes with recommendations on how to improve the quality of right-to-die decisionmaking. An absorbing read with a minimum of technical jargon, this book is a valuable guide to care givers, public policy students, medical ethicists, family members, and anyone facing questions about an individual's right to di

Scaling betweenness centrality using communication-efficient sparse matrix multiplication
Betweenness centrality (BC) is a crucial graph problem that measures the significance of a vertex by the number of shortest paths
leading through it. We propose Maximal Frontier Betweenness Centrality (MFBC): a succinct BC algorithm based on novel sparse matrix multiplication routines that performs a factor of p 1/3 less communication on p processors than the best known alternatives, for
graphs withn vertices and average degree k = n/p 2/3. We formulate, implement, and prove the correctness of MFBC for weighted graphs by leveraging monoids instead of semirings, which enables a surprisingly succinct formulation. MFBC scales well for both extremely sparse and relatively dense graphs. It automatically searches a space of distributed data decompositions and sparse matrix multiplication algorithms for the most advantageous configuration. The MFBC implementation outperforms the well-known CombBLAS library by up to 8x and shows more robust performance. Our design methodology is readily extensible to other graph problems
