19. 06. 2015Multi-RAPL - Sharing RAPL energy counters between applicationsTill SmejkalTU DresdenVortrag zum Forschungsprojekt
In this talk I will present how an adaption of the Linux scheduler allows us to use the RAPL energy counters to measure the energy usage of any program while it is running in an, apart from the scheduler, unchanged environment. This facilitates us to collect accurate energy statistics for them, without the influences of other parallel running programs, while they are executed in their normal environment. While such measurements yield significant errors if one uses pure RAPL, Multi-RAPL can provide good results, as it will be shown with energy consumptions for parallel executions of the benchmarks from the NAS Parallel Benchmark suite. 19. 06. 2015RDMA-accelerated Key-Value-stores demystifiedHannes WeisbachTU DresdenVortrag zum Forschungsprojekt
In this talk I will give a brief introduction into the RDMA architecture, programming with libibverbs/librdma_cm, and implementing client-server scenarios. I will subsequently discuss design trade-offs in Pilaf and Hydra, my own RDMA Key-Value-store implementation, and show why HERD achieves superior performance to both implementations. |
