Hardware and software requirements¶
x86_64 or ppc64le CPU architecture
NVIDIA data center GPUs, of the SM70 (Volta) or SM80 (Ampere) architecture
All GPUs should be
or connected via GPUDirect RDMA over Infiniband using a Mellanox adapter (CX-4 or later)
Note that being merely connected via PCIe does not guarantee peer-to-peer access between GPUs. Also note that NVLink is not required for peer-to-peer access, but it is the preferred transport.
cuFFTMp is shipped as part of the HPC SDK 22.3 and requires
Linux 64 bits
On x86_64, CUDA 11.2 or later. On ppc64le, CUDA 11.4 or later.
