Abstract :
The need of high performance low-cost computing systems motivates intense research in the field and some very fine results have been achieved. By clustering cheap personal computers together we place a virtual supercomputer at our disposal. Currently, PC cluster are mainly programmed using message passing programming models. The SCI interconnect technology opens the possibility for shared memory models. In order to profit from all the advantages that SCI offers, an Application Programming Interface for SCI based systems is needed. The SISCI API provides the necessary tools for developing SCI based systems applications like performance tests and other similar utilities. This paper presents an easy application which uses the SCI API functions and was developed to measure the total bandwidth of a cluster. Four PCs with Pentium II and running under Windows NT 4.0 were connected via Dolphin´s 4-port switch
