This post shows how to run on RISC-V CPUs with vector extensions.</li> </ul> <h2 id="h2-1-introduction">Introduction</h2> <p><a href="https://riscv.org/" title="RISC-V" target="_blank" rel="noopener noreferrer">RISC-V</a> is an open standard instruction set architecture (ISA) based on the principles of reduced instruction sets (RISC). RISC-V is freely available under open licences, allowing anyone to design, modify and implement RISC-V processors.</p>https://foojayio.github.io/website/today/the-tornadovm-programming-model-explained/Tue, 28 May 2024 11:01:14 +0000https://foojayio.github.io/website/today/the-tornadovm-programming-model-explained/<h2 id="h2-0-key-takeaways">Key Takeaways</h2> <p><img src="https://raw.githubusercontent.com/jjfumero/jjfumero.github.io/master/files/blog/24-02-prog-model/back.jpg" alt="" loading="lazy"> </p> <ul> <li><a href="https://github.com/beehive-lab/TornadoVM/" target="_blank" rel="noopener noreferrer">TornadoVM</a> offers an API for parallel programming on modern hardware that tackles data parallel, task parallel and pipeline parallel applications.</li> <li>TornadoVM offers different abstractions to developers to be able to express parallel applications in Java, identify the methods to offload, and dispatch the application on the corresponding accelerators.</li> <li>Task-Graphs and Execution Plans are the main building blocks of TornadoVM applications, allowing developers to compose complex graphs of computations and interact with the TornadoVM runtime to enable/disable profiling, enable debugging, or enable dynamic reconfiguration to select the best possible accelerators for the compute graphs.</li> </ul> <p>In this blog post, I will explain how developers can start programming with TornadoVM and interact with the TornadoVM runtime.</p>
