Abstract	The authors introduce an efficient indexing organization which provides for parallel retrievals. Given a p-processor massively parallel computer, the organization allows a maximum of p retrievals to be performed concurrently and thus achieves an approximate speed up of p in the best case. The index structure is based on the multi-B-tree index structure. It is compatible with current automatic retrieval and query processing techniques. It is also compatible with a variety of file organizations. In addition to an indexed attribute which the authors refer to as primary attribute, a secondary attribute can be included in the index as no additional cost. Updates are achieved with a high degree of efficiency as well. The parallel organization of a multi-B-tree index improves considerably the performance of the index. The method discussed here can be easily applied to standard B+ tree, B/sup */ tree and other B tree variations.
