Second Workshop on Communication, I/O, and Storage at Scale on Next-Generation Platforms - Scalable Infrastructures -

Next-generation HPC platforms must have to deal with increasing heterogeneity in their subsystems. These subsystems include internal highspeed fabrics for inter-node communication; storage system possibly integrated with programmable data processing units (DPUs) and infrastructure processing units (IPUs) to support software-defined networks; traditional storage infrastructures with global parallel POSIX-based filesystems complemented with scalable object stores; and heterogeneous compute nodes configured with a diverse spectrum of CPUs and accelerators (e.g., GPU, FPGA, AI processors) having complex intra-node communication. The workshop will pursue multiple objectives, including: (1) develop and provide a holistic overview of next-generation platforms with an emphasis on communication, I/O, and storage at scale, (2) showcase application-driven performance analysis with various HPC fabrics, (3) present early experiences with emerging storage concepts like object stores using next-generation HPC fabrics, (4) share experience with performance tuning on heterogeneous platforms from multiple vendors, and (5) be a forum for sharing best practices for performance tuning of communication, I/O, and storage to improve application performance at scale and any challenges.
