The DADO Machine Software

The "iron" behind DADO is only one part of the story. My project at Columbia successfully developed a wide range of software systems for DADO.

The Kernel Operating System

The Kernel OS for DADO allowed the machine to serve as an "attached peripheral" to a host implementing several modes of parallelism including SIMD, SPMD, MSIMD and MSPDM. DADO introduced Single Program Multiple Data mode of parallelism to massively parallel architectures.

Parallel Languages

The kernel also directly supported a number of parallel high level languages including parallel variants of LISP, C and PL/M. These were fully functional and broadly applicable programming languages.

Application environments

With these we developed a number of application environments including a parallel version of OPS5 to run production system programs at high speed, DQL to run a limited range of SQL queries, LPS a logic programming system, as well as dynamic programming, dynamic time warp matching and clustering for a wide range of statistical pattern matching tasks, at very high speeds.
