WebMar 27, 2016 · Sparse matrix-vector multiplication (SpMV) is an important operation in scientific computations. Compressed sparse row (CSR) is the most frequently used format to store sparse matrices. However, CSR-based SpMVs on graphic processing units (GPUs), for example, CSR-scalar and CSR-vector, usually have poor performance due to … WebNov 28, 2015 · In CSR(scalar) format, a thread is assigned to process each row. By doing so, some difficulties may occur (such as thread divergence) leading to performance degradation. To solve this problem, CSR(vector) format was proposed .
