Due to their excellent cost/performance ratio, clusters of PCs can be attractive high performance computing (HPC) platforms. However, their limited communication performance over standard LANs is restrictive for parallel applications. It is the goal of the SMiLE project (Shared Memory in a LAN-like Environment) at LRR-TUM to overcome this performance gap by adopting the SCI interconnect technology (Scalable Coherent Interface). With hardware-based distributed shared memory (DSM) and high performance communication characteristics (throughput in the range of tens of Mbytes/s and latencies in the range of a few microseconds), a cluster built on top of this interconnection technology is regarded as well suited for HPC.
