Jahanzeb Hashmi is currently a fifth-year Ph.D. student at The Ohio State University where he works at Network-Based Computing Laboratory (NBCL). Before joining NBCL, he was a graduate fellow at the Department of Computer Science and Engineering, Ohio State University. His research is mainly targeted at enabling high-level programming models and runtime systems to achieve high-performance and scalability on dense manycore architectures. He works on the areas related to shared-memory and shared-address-space communication, machine-aware communication protocols, and runtime optimizations and semantic enhancements related to MPI, PGAS, and MPI+X runtimes for modern CPUs and interconnects. Prior to joining OSU, he completed his MS in computer engineering at Ajou University, South Korea under the Korean Global IT fellowship where he worked on the performance evaluation and characterization of energy-efficient clusters for scientific workloads. He received his BS from National University of Science and Technology, Pakistan under the Prime Minister's ICT fellowship.
