Are Your Programs Doing What You Think They're Doing? Introducing Monitoring Tools for Multicore OCaml
As programs grow in size and complexity, they become more challenging to optimise. When the cause of a particular performance issue can theoretically be attributed to multiple sources, developers need concrete data to drive their decision making and avoid time-consuming guesswork. As you can imagine…

What are Data Races? And do They Threaten Your Business?
Imagine you have a brand-new coffee machine. One morning, you traipse excitedly down the stairs only to discover that, alas, your appliance has turned into a potato. The next day, it turns back into a coffee machine. And so it continues: on some days, it dispenses you perfect, frothy coffee; on othe…

Off to the Races: Using ThreadSanitizer in OCaml
OCaml Multicore opened up a new world of performance for developers, something that Nomadic Labs has tested with great results. Rather than relying on one core to do everything, the program can take advantage of multiple cores simultaneously for a significant performance boost. With new programming …
