Optimization techniques have been used to deploy very large memory (VLM) database technology on Digital’s AlphaServer 8400 multiprocessor system. VLM improves the use of hardware and software caches, main memory, the I/O subsystems, and the Alpha 21164 microprocessor itself, which in turn causes fewer processor stalls and provides faster locking. Digital’s 64-bit AlphaServer 8400 system running database software from a leading vendor has achieved the highest TPC-C results to date, an increased throughput due to increased database cache size, and an improved scaling with symmetric multiprocessing systems.
