But ARM servers lack software support as most server applications are written for x86 chips. But Hadoop, OpenStack and the LAMP stack already support ARM, and native Java support is coming in 2015.
Nvidia at ISC is also announcing CUDA 6.5, a set of proprietary parallel programming tools that can harness the joint computing power of CPUs and GPUs. CUDA 6.5 adds support for ARM processors.
Beyond AppliedMicro, Nvidia is keeping a close watch on other ARM-based server chip makers such as Broadcom and Cavium, Buck said. He hinted that GPU support could also come for those chips.
Nvidia faces competition from AMD, which is developing an ARM server processor and sells graphics processors such as FirePro for the supercomputing space. Nvidia lacks a CPU specifically for servers and is not developing one, Buck said.
