Title: I/O scheduling for HPC: finding the right access pattern and mitigating interference
Abstract: Scientific applications are executed in a high performance computing (HPC) environment, where a parallel file system (PFS) provides access to a shared storage infrastructure. The key characteristic of these systems is the use of multiple storage servers, from where data can be obtained by the clients in parallel. The performance observed by applications when accessing a PFS is directly affected by the way they perform this access, i.e. their access pattern. Additionally, when multiple applications concurrently access the PFS, their performance will suffer from interference.
In this seminar, I’ll discuss my previous and current work with I/O scheduling at different levels of the I/O stack, adapting policies to applications’ access patterns and working to mitigate interference
