Investigation of hardware compression on IBM Power9 - Dr. Jerome Kieffer et al
From the HDF5 European Workshop for Science and Industry, held 17-18 September 2019 at ESRF Grenoble.
This contribution presents how the gzip compression engine integrated into the IBM Power9 processor can be used with the HDF5 storage to provide faster saving of actual diffraction data compared to the software compression.
The default compression provided as part of HDF5 will be compared with meta-compressors like Blosc. A few pre-compression filters will be presented and their performances compared with HDF5.
