WebJan 1, 2015 · We take the hash-based SpGEMM implementation as the baseline for the comparison. The main performance gain comes from using a dense array instead of … WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
WebApr 5, 2024 · This Hash SpGEMM for multi/many-core processors differs from the GPU version as follows. While a row of output is computed by multiple threads in the GPU version to exploit massive number of threads on GPU, each row is processed by a single thread in the present algorithm. Hash SpGEMM on GPU requires some form of mutual exclusion … WebIt is well known that SpGEMM is a memory-bound operation, and its peak performance is expected to be bound by the memory bandwidth. Yet, existing algorithms fail to saturate the memory bandwidth, resulting in suboptimal performance under the Roofline model.
Webaccelerator for SpGEMM computation: (1) the inner product and outer product algorithms, which perform well for dense matrix multiplication, are not necessarily the ideal algorithms for SpGEMM due to the low densities of the sparse matrices involved in the computation; (2) the SpGEMM computation is highly memory-bound and the traditional sparse ... WebApr 5, 2024 · We firstly identify and mitigate multiple bottlenecks with memory management and thread scheduling on Intel Xeon Phi (Knights Landing or KNL). Specifically targeting multi- and many-core processors, we develop a hash-table-based algorithm and optimize a heap-based shared-memory SpGEMM algorithm.
