Rockstar🎓
Top SchoolTerry Cojean is a Technical Expert in High-Performance Computing with eight years of experience building and optimizing parallel and heterogeneous software for scientific simulation and sparse linear algebra. A lead developer on the Ginkgo project, he has driven modern C++ design, accelerator support (AMD HIP, Intel DPC++), benchmarking, and CI to make numerical algorithms performance-portable across GPUs and manycore CPUs. His work on Spack improved packaging and testing for Ginkgo, reflecting a pragmatic DevOps mindset alongside deep algorithmic expertise. Earlier research at Inria produced novel moldable-task runtimes that improved task granularity and outperformed existing dense linear algebra libraries on heterogeneous systems. Based in Toulouse, France, he blends reproducible-research practices with a focus on sustainable, extensible HPC software.
