Compressing Checkpoints in MITgcm Adjoint Computations Efficient computation of the gradients used for state estimation in the MITgcm general circulation model requires saving intermediate states to disk. We present some preliminary experiments on compressing these checkpoints in order to reduce the time to read and write checkpoints or to increase the number of checkpoints written …

Hugo Taboada defends his PhD thesis
Hugo Taboada will defend his PhD thesis entitled “MPI Non-Blocking Collective Overlap on Manycore Processor” on Tuesday, December 11th at 10:00 AM. Supercomputers used in HPC are composed of severals inter-connected machines. Usually, they are programmed using MPI which specify an API for messages exchanges between machines. To amortize the cost of MPI collective …

Nicolas Denoyelle defends his PhD thesis
Nicolas Denoyelle will defend his PhD thesis entitled “From Software Locality to Hardware Locality in Shared Memory Systems with Heterogeneous and Non-Uniform memory“, on Monday, November 5th at 2:00 PM. Through years, the complexity of High Performance Computing (HPC) systems’ memory hierarchy has increased. Nowadays, large scale machines typically embed several levels of caches and …

Optimal Cooperative Checkpointing for Shared High-Performance Computing Platforms joint work with Dorian Arnold, George Bosilca, Aurelien Bouteiller, Jack Dongarra, Kurt Ferreira and Thomas Hérault Abstract: In high-performance computing environments, input/output (I/O) from various sources often contend for scarce available bandwidth. Adding to the I/O operations inherent to the failure-free execution of an application, I/O from …
