By exploiting both data and pipeline parallelism, our prototype indexer efficiently builds a partitioned inverted compressed index, a suitable data structure commonly utilized by modern Web Search Engines. We discuss implementation issues and report the results of preliminary tests conducted on a SMP PCs.
