## Why It Matters
Delta matters as a documented example of an Intel-manufactured supercomputer with clearly recorded TOP500-style performance metrics and configuration details. Its inclusion with a TOP500 system identifier (547) makes it a reference point for historical comparisons of supercomputing systems and their measured performance. The entry also ties Delta to OSF/1, a Unix variant from the Open Software Foundation, and to the Tru64 UNIX operating system family, situating it within a specific lineage of Unix-based high-performance computing environments. The presence of repeated performance records across multiple dates (1996–1998) provides a consistent snapshot of its measured (Rmax) and theoretical peak (Rpeak) performance values over time. For researchers, educators, and system historians, Delta is useful because it combines manufacturer attribution, operating system information, core count, and standardized performance figures in one place.
