Renowned expert in system performance optimization, known in the tech community as the "God of Performance," Brendan Gregg has officially joined OpenAI. The author of the industry textbook "High Performance Computing," Gregg will directly join the ChatGPT performance team after his appointment, helping OpenAI overcome computational bottlenecks behind large models through remote work in Australia.
Gregg's arrival has caused a significant stir in the AI community, with OpenAI President Brockman openly expressing his excitement and admitting he has been a long-time fan of Gregg's work. As a legendary figure who invented "Flame Graphs" and deeply promoted Linux kernel eBPF technology, Gregg has transformed system diagnostics from "mysticism" into science during his tenure at top tech companies such as Sun Microsystems, Netflix, and Intel, solving numerous complex low-level performance issues.
When asked about his motivation for joining OpenAI, Gregg said that AI has become a tool used daily by people across all industries, and the massive traffic pressure has made traditional general computing tuning methods less effective. In his view, with super clusters consisting of tens of thousands of GPUs, it is necessary to break the norm and find a new performance balance between scalability and speed. Additionally, he revealed that joining OpenAI was actually fulfilling a "science fiction dream"—to make ChatGPT become the arrogant yet powerful supercomputer from his childhood idol's show.
