Digital Technical Journal

This volume of the Digital Technical Journal (Vol. 8, No. 2, 1996) focuses on four key engineering developments from Digital Equipment Corporation:

• Spiralog File System: A new clusterwide, log-structured file system integrated with OpenVMS 7.0, designed for high data availability and performance.
• OpenVMS 64-bit Virtual Memory: Enhancements to the OpenVMS operating system to support 64-bit virtual addressing on Alpha architecture, while maintaining binary compatibility for 32-bit applications.
• High-Performance Message Passing: The implementation of message-passing systems (PVM and MPI) for MEMORY CHANNEL clusters to enable low-latency communications.
• Speech Recognition Software: The design of user interfaces for the Digital Speech Recognition Software (DSRS) product integrated into the UNIX desktop environment.
