Masoud Jami, né Gholami, of ZIB successfully defended his PhD thesis at the Institute of Computer Science, Humboldt-Universität zu Berlin on October 10, 2024. He enhanced C/R techniques by reducing overhead by more than 10% compared to state-of-the-art, and outperforms Reed-Solomon codes by combining XOR and partner checkpointing in terms of resiliency and computational overhead. His IOSIG plugin for GCC adds pragma annotations to specify I/O characteristics of certain streams, enabling injected code to choose optimal devices during runtime. His accurate I/O models of the Linux kernel that consider page caching behavior estimate I/O costs with over 80-90% accuracy.
Congratulations!
