Combining checkpointing and data compression for large scale seismic inversion Seismic inversion is a class of adjoint-based optimization problems that process up to terabytes of data, regularly exceeding the memory capacity of available computers.Data compression is an effective strategy to reduce this memory requirement by a certain factor, particularly if some loss in accuracy is …

Talk by Paul Hovland (Argonne Nat Lab) on December 13th
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 …
