  • Develop and optimize system-level code using C++ and other languages to support HPC needs.
  • Apply advanced compiler optimizations and profiling tools, such as Intel VTune and perf, to identify and resolve performance issues.

Networking and Infrastructure:

  • Employ high-performance, low-latency network interfaces like Solarflare or Mellanox and apply kernel bypass techniques using DPDK or PF_RING.
  • Maintain precise time synchronization using Time-Sensitive Networking (TSN) and protocols like Precision Time Protocol (PTP) and GPS-based NTP servers.
  • Utilize and manage network monitoring tools like Corvil to track and reduce latency.
