โฆ Synopsis
We present pSPADE, a parallel algorithm for fast discovery of frequent sequences in large databases. pSPADE decomposes the original search space into smaller suffix-based classes. Each class can be solved in main-memory using efficient search techniques and simple join operations. Furthermore, each class can be solved independently on each processor requiring no synchronization. However, dynamic interclass and intraclass load balancing must be exploited to ensure that each processor gets an equal amount of work. Experiments on a 12 processor SGI Origin 2000 shared memory system show good speedup and excellent scaleup results.

A coarse-grain parallel program typically has one thread (task) per processor, whereas a finegrain program has one thread for each independent unit of work. Although there are several advantages to fine-grain parallelism, conventional wisdom is that coarse-grain parallelism is more efficient. This p
