Arun Viswanathan has been appointed the vice president of AI infrastructure at megachip company Cerebras Systems.

Viswanathan was previously the group VP of engineering on the core engineering team at Juniper Networks, where he spent 14 years.

At Juniper, he led Juniper's Routing Protocol Daemon (RPD) team. Prior to that role, he spent more than eight years at Force10 Networks as VP of engineering, where he worked on ASIC-based products.

Cerebras Systems develops wafer-scale chips, with its Wafer Scale Engine 3 boasting four trillion transistors and 900,000 'AI cores,' alongside 44GB of on-chip SRAM. Sold as part of the CS-3 system, the company claims the chip is capable of 125 peak AI petaflops.

As well as selling the chips, the company is developing multiple US supercomputers as part of a $900 million deal with G42.

Last month, Cerebras confidentially filed for an IPO with the SEC - although share price and market cap have yet to be revealed.
