Explore building a Node.js addon with HPX, a C++ parallelization framework. This article covers the integration challenges, such as managing asynchronous operations and reducing performance overhead. Learn how batch predicate functions can enhance the performance of complex algorithms like countIf and sort, while simpler tasks see limited gains. Ideal for developers interested in combining JavaScript with parallel C++ capabilities, the guide includes practical examples and benchmark results.

This article explores the powerful parallelization and distributed computing capabilities of the HPX framework. Starting with installation on macOS, it walks through configuring, compiling, and testing HPX on a modest machine, highlighting key features like asynchronous programming, task-based parallelism, and HPX components. Whether new to HPX or looking for practical examples, this guide offers a hands-on approach to understanding and utilizing HPX in real-world scenarios.

In this installment we’ll be talking about Transactions. As we already know a Bitcoin Block contains a Header and a collection of Transactions. We’ve already learned about how important Headers are and how they constitute a back-linked block-chain that helps to maintain the integrity of recorded transactions. Now the two new questions are: What does a Transaction look like? and How do we use it to transfer coins from address to address? And just like in the previous article I’ll be presenting a simplified C++ code here, while the real C++ code will be pointed to via links to Bitcoin’s […]
Yesterday, I discovered an experimental Big Data processing framework written in C++ called Thrill. As most of you surely know, the well-known frameworks of this kind are mostly based on JVM, like Apache Spark or Apache Flink. This, of course, has many advantages, like easily accessible interfaces and a more domain-oriented approach, as we don’t have to deal with “Ceremony Code” or any internals that don’t touch our domain logic. However, everything comes at a cost and utilizing a VM is a price to be paid no matter how optimized your code is. It’s no wonder these projects often resort to […]
