A learning experience toward the understanding of abstraction-level interactions in parallel applications

Alejandro Valero, Rubén Gran-Tejero, Darío Suárez-Gracia, Emanuel A. Georgescu, Joaquín Ezpeleta, Pedro Álvarez, Adolfo Muñoz, Luis M. Ramos, Pablo Ibáñez
2021 Journal of Parallel and Distributed Computing  
Each lab focuses on a single abstraction level, but shows students the interactions with the rest of the levels.  ...  Isolating such concepts in courses helps students not only to focus on specific aspects, but also to experience the reality of working with modern computer systems, where those concepts are often detached  ...  In the laboratory sessions of the course, OpenMP is presented and used as a tool for parallel programming of computers, as well as tools for performance measurement.  ...

APL since 1978

Roger K. W. Hui, Morten J. Kromberg
2020 Proceedings of the ACM on Programming Languages (PACMPL)  
Today, APL runs on PCs and tablets, Apples and Raspberry Pis, smartphones and watches. The operating systems, and the software application platforms that APL runs on, have evolved beyond recognition.  ...  As the demand for computing resources grew and costs dropped, APL first moved in-house to mainframes, then to mini-and micro-computers.  ...  of them as "abstract characters".  ...
