Spmv with multile right hand sides

Web17 Apr 2012 · The main features of our implementation are: (1) it is based on CUBLAS library for accelerating inner products, and (2) two different kernels for SpMVs are tested (CUSPARSE and ELLR-T). Hereinafter, when CUSPARSE or ELLR-T routines are used, they will be referred to as CuBCG CS or CuBCG ET , respectively. Web11 Apr 2024 · Approaches trying to remedy this are generally based on reducing memory traffic [1], solving multiple right-hand sides (RHSs) [35], using mixed-precision algorithms [8] or adapting more compute-intensive methods [7], [30], [17].

Web2 Nov 2016 · I had a meeting this morning so I haven't had a chance to look again. If @bmpersc says that we need to get this out today, I have an idea for a temporary work-around (just disable optimizing for multiple right-hand sides). Otherwise, I would prefer to wait and take a look, working with the code's original author, who is unavailable today. WebThis paper implements three block algorithms for parallel SpTRSV on modern GPUs, and proposes an adaptive approach that can automatically select the best kernels according to input sparsity structures, which is highly efficient for multiple right-hand sides and iterative scenarios. 10 PDF View 1 excerpt, cites background how to expand artboard in photoshop https://benoo-energies.com
