Most developers use automatic instrumentation without knowing how it actually works. This post breaks down the key techniques behind it—not to build your own, but to understand what’s really happening when things “just work.” Read the full articles on: Causely Blog, OpenTelemetry Blog

Maintenance involves functional checks, servicing, repairing, or replacing necessary devices, equipment, machinery, building infrastructure, and supporting utilities This definition from Wikipedia aptly describes what we, as maintainers, do. A significant portion of our time is spent on upkeep. While some of this work is enjoyable, many tasks are tedious and exhausting. To alleviate this, we are exploring ways to automate some of these tasks. One popular option is incorporating GitHub Actions into our repository. ...

While OpenTelemetry (OTel) is here to help you with troubleshooting and handling the “unknown unknowns”, it is also instrumental for managing route tasks like monitoring system metrics, like disk usage, server availability or SSL certificate expiration dates. This can be achieved by utilizing any one of the 90+ receivers available for the OpenTelemetry Collector, such as the Host Metrics Receiver or the HTTP Check Receiver.

OpenTelemetry is here to help us find the root cause of issues in our software quickly. We recently had an issue that we were able to fix by using one feature of OpenTelemetry to identify the root cause of bug in another feature. Read the full article on OpenTelemetry Blog

Apache HTTP Server and NGINX are the most popular web servers. It’s most likely that you are using one of them in your application. In a previous blog post, you learned how to use the OpenTelemetry Module for Apache HTTP Server to add observability to Apache HTTP Server. In this blog post, you will learn how you can get observability for NGINX! Read the full article on OpenTelemetry Blog ...

In applications of symbolic computation an often required but complex procedure is the computation of Gröbner bases and hence it is obvious to realize parallel algorithms to compute them. There are parallel flavours of the F4 algorithm using the special structure of the occurring matrices to speed up the reduction. In this paper we start from this and present modifications allowing efficient computations of Gröbner bases on parallel architectures using shared as well as distributed memory. To achieve this we concentrate on one objective: reducing the memory consumption and avoiding communication overhead. We remove unrequired steps of the reduction, split the columns of the matrix in blocks for distribution and review the effectiveness of the SIMPLIFY function. Finally we provide benchmarks with up to 256 distributed threads of an implementation which will be available at https://github.com/svrnm/parallelGBC. ...

In this paper we provide an parallelization for the reduction of matrices for Gröbner basis computations advancing the ideas of using the special structure of the reduction matrix. First we decompose the matrix reduction in three steps allowing us to get a high parallelization for the reduction of the bigger part of the polynomials. In detail we do not need an analysis of the matrix to identify pivot columns, since they are obvious by construction and we give a rule set for the order of the reduction steps which optimizes the matrix transformation with respect to the parallelization. Finally we provide benchmarks for an implementation of our algorithm. This implementation is available as open source. ...
