We revisit and use the dependence transformation method to generate parallel algorithms suitable for cluster and grid computing. We illustrate this method in two applications: to obtain a systolic matrix product algorithm, and to compute the alignment score of two strings. The product of two n × n matrices is viewed as multiplying two p × p matrices whose(More)

Nowadays several information retrieval services are being offered to mobile clients. Many of such services are implemented by groups of distributed servers and sometimes employ time-consuming data location and retrieval protocols among the servers. Moreover, many network applications have strong reliability requirements. This means that client-server(More)
In order to determine the clinical features of hepatocellular carcinoma in the elderly, a total of 622 patients with hepatocellular carcinoma, including 91 patients 70 years or older, were retrospectively analysed with reference to their ages at the time of diagnosis. The proportion of females increased and that of hepatitis B surface antigen-positive cases(More)
The systolic array paradigm has low communication demand because it does not use costly global communication and each processor communicates with few other processors. It is thus suitable to be used in cluster computing. The systolic approach, however, is vulnerable in a heterogeneous environment where machines perform differently. In this paper we propose(More)
