NVIDIA HPCG 基准利用 NVIDIA 高性能数学库：cuSPARSE 和 NVPL Sparse，在 NVIDIA GPU 和 Grace CPU 上实现稀疏矩阵向量乘法 (SpMV) 和稀疏矩阵三角求解器 (SpSV) 的最高性能。NVIDIA HPCG 基准支持高度可配置的命令行参数，以决定：GPU 和 Grace CPU 的问题大小 三维等级网格形状 执行模式： 纯 CPU、纯 GPU ...
图2 还显示了仅使用 NVIDIA HPCG GPU 的配置以及异构 GPU 和 Grace CPU 实施的性能,当 Grace CPU 处理可能与 GPU 工作负载重叠的较小问题时,与仅使用 GPU 的设置相比,后者的性能提升了 5%。Grace CPU MPI 排名可以额外处理 GPU 问题大小的 1/16,与在 CPU 上执行的官方 HPCG 基准测试相比,速度提升了 ...
另外虽然能效不如 AC922+V100 那种 CPU+GPU 结构, 但是 GPU 跑运算的最大问题还是控制流的性能不如 CPU, 实际跑很多场景这种 CPU SIMD 还是有优势的, 只能说纯粹刷算力 GPU 仍然是首选, 只要场景得当能效和价格都是可以的. 另外就是给 Apple 这样的可能未来会有 HEDT ARM 产品线的厂商摸清道路, 这个 SVE ...
The NVIDIA A100 (Compute) GPU is an extraordinary computing device. It’s not just for ML/AI types of workloads. General scientific computing tasks requiring high performance numerical linear algebra run exceptionally well on the A100. Intel Rocket Lake Compute Performance Results HPL HPCG NAMD and...
Regarding compatibility, NVIDIA's HPCG is supported at Grace CPU systems along with Ampere and Hopper GPU architectures. The software only works with Linux as well, which is something that limits its scope. However, it's still an interesting move by NVIDIA, and it shows their commitment to op...
Figure 1 shows an example of this design. The GPU and Grace CPU ranks have the sameyandzdimensions. Thexdimension is different, which enables assigning different local problems for the GPU and Grace ranks. The NVIDIA HPCG benchmark program offers you the flexibility to choose the 3D shape of...
NVIDIA HPCG Benchmark supports CPU-only, GPU-only and heterogeneous execution modes The scripthpcg-aarch64.shcan be invoked on a command line or through a Slurm batch-script to launch the NVIDIA HPCG Benchmarks. The scripthpcg-aarch64.shaccepts the following parameters: ...
国产异构系统上的HPCG并行算法及高效实现
NAMD is a very good molecular dynamics program with excellent parallel scalability. It makes a good benchmark because it is easy to setup and use and has good performance on a wide range of platforms. It was also one of the early codes to ta...
