HPC Storage & I/O Optimization
Data Placement on Heterogeneous & Multilevel Storage Systems
Hello! I am Hocine Mahni, a PhD researcher at the Lab-STICC laboratory, affiliated with ENSTA | Institut Polytechnique de Paris.
My research focuses on data placement strategies for heterogeneous and multilevel storage systems, particularly in the context of high-performance computing. I am interested in improving I/O efficiency, storage resource utilization, and data management policies for large-scale scientific applications.
