DCompute: Running D on the GPU

Posted on

DCompute is a framework and compiler extension to support writing native kernels for OpenCL and CUDA in D to utilize GPUs and other accelerators for computationally intensive code. Its compute API drivers automate the interactions between user code and the tedious and error prone APIs with the goal of enabling the rapid development of high performance D libraries and applications.

DMD, Windows, and C

Posted on

Before diving into a series about C and D, a bit of a primer is called for. That’s where this post comes in. The primary goal is to help ensure a C environment is installed and working on Windows. It’s also useful to understand why things are different on that platform than on the others. Before we get to the why, we’ll dig into the how.

Unit Testing In Action

Posted on

Ten years ago, programming in D was like starting over in our company. And, of course, unit testing was part of it right from the beginning. D’s built-in simple support made it easy to quickly write lots of unit tests. Until some of them failed. And soon, the failure became the rule. There’s always someone else to blame: D’s simple unit-test support is too simple. A look at Python reveals that the modules doctest and unittest live side by side in the standard library. We concluded that D’s unit test support corresponds to Python’s doctest, which means that there must be something else for the real unit testing.

The Evolution of the accessors Library

Posted on

We’ve always used UML tools to visualize the internal structure and document details of software. That’s true for me not only at Funkwerk, but also in the companies I worked before I joined the team here in Karlsfeld. One of the major issues of documentation is that at some point in time it will diverge from the actual implementation and become outdated. Additionally, if you have to support old versions of your components you will have to take care of old versions of your documentation as well.

DMD 2.076.0 Released

Posted on

The core D team is proud to announce that version 2.076.0 of DMD, the reference compiler for the D programming language, is ready for download. The two biggest highlights in this release are the new static foreach feature for improved generative and generic programming, and significantly enhanced C language integration making incremental conversion of C projects to D easy and profitable.

Open Methods: From C++ to D

Posted on

I knew next to nothing about D. You see, I learned to program in Forth. Later I did some Lisp programming just for fun. To me, the idea of CTFE was natural right off the bat. So when Ali talked about static if and mixins, he definitely got my attention. In order to learn (and evaluate) D, I decided to reproduce parts of my C++ library yomm11.

D as a Better C

Posted on

There are large and immensely useful programs written in C, such as the Linux operating system and a very large chunk of the programs written for it. While D programs can interface with C libraries, the reverse isn’t true. C programs cannot interface with D ones. It’s not possible (at least not without considerable effort) to compile a couple of D files and link them in to a C program. The trouble is that compiled D files refer to things that only exist in the D runtime library, and linking that in (it’s a bit large) tends to be impractical.

That is, until Better C came along.

A DUB Case Study: Compiling DMD as a Library

Posted on

In his day job, Jacob Carlborg is a Ruby backend developer for Derivco Sweden, but he’s been using D on his own time since 2006. He is the maintainer of numerous open source projects, including DStep, a utility that generates D bindings from C and Objective-C headers, DWT, a port of the Java GUI library SWT, and DVM, the topic … Continue reading A DUB Case Study: Compiling DMD as a Library
