dc.description.abstractEn | The ever-growing level of parallelism within the multi-core and multi-processor nodes in clusters leads to the generalization of distributed memory banks and busses with non-uniform access costs. These NUMA effects have been mostly studied in the context of threads scheduling and are known to have an influence on high-performance networking in clusters. We present an evaluation of their impact on communication performance in multi-Opteron machines. NUMA effects exhibit a strong and asymmetric impact on high-bandwidth communications while the impact on latency remains low. We then describe the implementation of an automatic NUMA-aware placement strategy which achieves as good communication performance as a careful manual placement, and thus ensures performance portability by gathering hardware topology information and placing communicating tasks accordingly. | |
