Tycoon in Open Distributed Environments

Bernd Mathiske (3/93-3/96)

Goal

Exploitation of portable, typed persistent higher-order languages in the context of open distributed systems.

Work Items

1/92-12/92, Bernd Mathiske, [Math92]

Dynamic target code generation via C

1/94-8/94, Bernd Mathiske, [Info]

A portable and scalable runtime frame program implemented in C

• C-calls and transparent callbacks; Tycoon closures can be passed around and called in C as function pointers;
• Dynamic exception handling in C, Tycoon exception handling and mixtures of both;
• Multi-threading, persistence of threads;
• Basic persistent synchronization mechanisms.
