Jan Ciesko
Scalable Algorithms
Biography
Jan Ciesko is a Senior Member of Technical Staff at Sandia National Laboratories in the scalable algorithms group. He holds a master’s degree in computer science from Friedrich-Alexander Universität in Germany and a Ph.D. from Universitat Politècnica de Catalunya (BarcelonaTech) in Spain. Jan works on programmability and performance portability of software on modern supercomputers. He is the developer of PGAS support in the Kokkos Performance Portability Framework and leads development efforts of the Qthreads user-level threading library. He periodically contributes to Kokkos, MPICH, Libevent, Open MPI and other software packages. He participates in industry forums such as NVIDIA Corporation’s Summit on Summit, Sierra, and Perlmutter (SoSSP), and the Open MPI Forum and has developed collaborations with industry and academic partners including AMD Research, HPE, GeorgiaTech, and the University of Tennessee (UTK) to cover Sandia’s research interests in his field. Before joining the Sandia National Laboratories, he was a post-doc at the Barcelona Supercomputing Center. His work has been published at IPDPS, ICS, HPEC, IWOMP and ExaMPI.
