Exploring the Capacity of a Modern SMT Architecture to Deliver High Scientific Application Performance ⋆
- …Abstract. Simultaneous multithreading (SMT) has been proposed to improve system throughput by overlapping instructions from multiple threads on a single wide-issue processor. Recent studies have demonstrated that heterogeneity of simultaneously executed applications can bring up significant performa…

Tuning Blocked Array Layouts to Exploit Memory Hierarchy in SMT Architectures
- …Abstract. Cache misses form a major bottleneck for memory-intensive applications, due to the significant latency of main memory accesses. Loop tiling, in conjunction with other program transformations, have been shown to be an effective approach to improving locality and cache exploitation, especial…

Understanding the performance of sparse matrix-vector multiplication
- …In this paper we revisit the performance issues of the widely used sparse matrix-vector multiplication (SpMxV) kernel on modern microarchitectures. Previous scientific work reports a number of different factors that may significantly reduce performance. However, the interaction of these factors with…
