Depending on the topologies of these memory networks we find everything from true data sharing with shared caches to distributed memory architectures which just pretend to be physical shared memory systems. In fact, most many-cores are hybrid systems that exhibit the characteristics of both distributed systems and SMPs. In this paper we argue in favor of middleware platforms for many-cores. We will discuss the needed functionality in contrast to common distributed system middleware and present micro benchmarks on several architectures to substantiate our claims.}, language = {en} } @misc{RottaPrescherTraueetal., author = {Rotta, Randolf and Prescher, Thomas and Traue, Jana and Nolte, J{\"o}rg}, title = {In-Memory Communication Mechanisms for Many-Cores - Experiences with the Intel SCC}, series = {TACC-Intel Highly Parallel Computing Symposium (TIHPCS), Austin/Texas, 2012}, journal = {TACC-Intel Highly Parallel Computing Symposium (TIHPCS), Austin/Texas, 2012}, abstract = {Many-core processors combine fast on-chip communication with access to large amounts of shared memory. This makes it possible to exploit the benefits of distributed as well as shared memory programming models within single parallel algorithms. While large amounts of data can be shared in the memory and caches, coordinating the activities of hundreds of cores relies on cross core communication mechanisms with ultra low latency for very small messages. In this paper we discuss two communication protocols for the Intel SCC and compare them to the MPI implementation of the SCC. Our micro-benchmark results underline that special purpose protocols for small messages make much finer levels of parallelism possible than general purpose message passing systems.
