Duel GPU's cut my render time in half. NVLink Bridge is $80 and it's only effect is adding together the VRAM of both cards, so instead of 24 I would have 48gb of vram. 24 is plenty for everything I do right now. My softwares leverage duel GPUs 100%. Feeling a little bi...
you need to have thebest computer for 3D modelingthe market has to offer as well as one of the latest NVidia RTX GPUs. If you want to use this software with several RTX GPUs, you’ll also need an NVLink (SLI Bridge) since Arnold doesn’t properly scale across multiple cards without ...
which means GPU clock is always behind CPU clock. My hardware spec is A100 80GB x 4 with NVLink Bridge (GPU 0-1, 2-3 connected)Sign up for free to join this conversation on GitHub. Already have an account? Sign in to comment
you MUST have an NVLink (SLI Bridge) Arnold doesn’t scale well across cards without them. If you plan on sticking with Arnold CPU, you’re gonna want a process with a ton of threads. Maybe of the
BTW,here’sone more post about “p2p on RTX2080 not working without NVLINK bridge”. @njuffa, AFAIU, after all, the issue is not related to some unexpected incompatibility with 3rd party hardware. This functionality was simply intentionally removed. ...
以PCIe-topo和NVLink-topo机型为例,展示通过ACSpeed优化原理和优化性能效果。具体说明如下: PCIe-topo机型 问题分析 以没有P2P互联的8卡机型的GPU拓扑结构为例,GPU0~GPU7的各卡连接如下图所示。由于卡与卡之间没有P2P互联,且多卡共用PCIe带宽,在涉及多卡通信的分布式训练中,特别是通信数据量较大的场景,容易出现因...
