Nvidia’s new Turing architecture marks a significant departure for the company, offering dedicated ray tracing and tensor processors. On their workstation cards this make sense. But for consumers, is the added complexity and power worth the benefits?
Russ White considers the challenges of using GPU clusters in high performance computing. Aside from possibly lacking software to take advantage of it, the other challenge lies in the connection network. Ethernet is the default standard for this, but requires additional overhead. Russ sees using PCI Express as a much more efficient solution. He considers a PCIe switch from Liqid to dynamically compose infrastructure.
