Summary
🤩
Rockstar🎓
Top SchoolPaul Hargrove is a veteran computer systems engineer and researcher with a Ph.D. in Scientific Computing from Stanford and over two decades of hands-on experience building systems software for high-performance computing. Based at Lawrence Berkeley National Lab, he leads development of PGAS tools like UPC++ and the GASNet-EX communication layer and directs the DOE-funded Pagoda effort toward exascale-capable runtimes. An early Linux kernel contributor, his long-standing kernel work includes the Macintosh HFS driver and POSIX FIFO support—code that shipped well before Linux 1.0—highlighting a rare blend of low-level systems craftsmanship and distributed-memory networking expertise. He has also led production-quality projects such as Berkeley Lab Checkpoint-Restart (BLCR) and steered industry standards work on RDMA and direct-access transports. Based in Las Vegas, Paul combines academic rigor with practical delivery, often focusing on one-sided RMA, RPC, and scalable checkpointing for preemptive scheduling and fault tolerance.
