Composing Schedulers using Effect Handlers
Composing Schedulers using Effect Handlers Deepali Ande (IIT Madras) KC Sivaramakrishnan (IIT Madras and Tarides) OCaml 5 introduces effect handlers as a mechanism for con- current programming. With effect handlers, concurrency can be expre...
Continuous Monitoring of OCaml Applications Using Runtime Events
The upcoming 5.0 release of OCaml includes a new runtime tracing system designed for continuous monitoring of OCaml applications called Runtime Events. It enables very low overhead, programmatic access to performance data emitted by the OCaml runt...
Copying opam switches – it should Just Work™
Copying opam switches – it should Just Work™ David Allsopp (Tarides UK) OCaml’s ecosystem centres around compilation from source code, rather than precompiled binaries. The compiler itself is only provided as a source distribution and OCaml’...
