Abstract
The need of high-performance low-cost computing systems motivates intense r esearch in this field, and some very fine results have been achieved. By cl ustering cheap personal computers together, we placed a virtual supercomput er at our disposal. Currently, PC cluster are mainly programmed using messa ge passing programming models. The scalable coherent interface (SCI) interc onnect technology opens the possibility for shared memory models. To profit from all the advantages that SCI offers, an application programming interf ace (API) for SCI-based systems is needed. The SISCI API provides the neces sary tools for developing SCI-based systems applications like performance t ests and other similar utilities. This paper presents an easy application t hat uses the SCI API functions and was developed to measure the total bandw idth of a cluster. Four PCs with Pentium II and running under a Windows NT 4.0 server were connected via Dolphin's four-port switch. The application i s an example of what this SCI API can offer to any user who wants to develo p an SCI-based cluster application without the need of a wide knowledge on the SCI standard.
