The result is that compute 2.1 devices can execute a warp in a superscalar fashion for any CUDA code without requiring explicit programmer actions to force ILP. ILP has been incorporated into the CUBLAS 2.0 and CUFFT 2.3 libraries. Performing an single-precision level-3 BLAS matrix multiply (...
In the remainder of this section, we outline the basic components of AMG in an aggregation context [37] and highlight the necessary sparse matrix computations used in the process. We restrict our attention to aggregation methods because of the flexibility in the construction, however our ...

If we look at the computation in matrix form, it's easy to see how the matrix multiplication can be split between multiple GPUs: If we split the weight matrix A column-wise across N GPUs and perform matrix multiplications XA_1 through XA_n in parallel, then we will end up with N ...
In the new design, each expert will conduct a dense matrix multiplication of the whole batch, and then rows not assigned to the expert will be zeroed out before accumulation. This results in a slight inefficiency for tensor parallel sizes below the number of experts - it means that we will...
So an IVar lets you communicate values between parallel Par computations, because you can put a value in the box in one place and get it in another. Once filled, the box stays full; the get operation doesn’t remove the value from the box. It is an error to call put more than once...
Multi-level parallelism for incompressible flow computations on GPU clusters We investigate multi-level parallelism on GPU clusters with MPI-CUDA and hybrid MPI-OpenMP-CUDA parallel implementations, in which all computations are don... DA Jacobsen,Inane Senocak - 《Parallel Computing》 被引量: 40...
actually computing i+1, i+2, etc. Redundant computations both waste registers and needlessly consume power. Note, however, that a combination of compiler & hardware optimizations could eliminate the physical replication of redundant values. I don't know the extent to which it's done in reality...
