Abstract [en]

The Single Chip Cloud computer (SCC) is an experimental processor from Intel Labs with 48 cores connected with a 2D mesh on-chip network. We evaluate the performance of SCC regarding off-chip memory accesses and communication capabilities. As benchmark, we use the merging phase of mergesort, a representative of a memory access intensive algorithm. Mergesort is parallelized and adapted in 4 variants, each leveraging different features of the SCC, in order to assess and compare their performance impact. Our results motivate to consider on-chip pipelined mergesort on SCC, which is an issue of ongoing work.
