Abstract: | In contrast to disk or flash based storage solutions, throughput and latency of in-memory storage promises to be close to the best performance. Kove®’s XPD® offers pooled memory for cluster systems. For I/O intensive HPC applications, in particular for those with inefficient I/O access pattern, this technology provides a number of benefits. Our MPI independent file driver enables high-level I/O libraries (HDF5, NetCDF) to utilize the XPD’s pooled memory. We evaluate the benefit of this driver for synthetic and for user-relevant workloads. Contributions of this poster are: 1. Description of I/O capabilities of the XPD 2. Elaboration of benefits for shared file access with MPI-IO and NetCDF Authors: Julian Kunkel, Deutsches Klimarechenzentrum Eugen Betke, Deutsches Klimarechenzentrum |
