Heading Towards the (Alternate) Wedding Church
Chapel is a modern programming language designed for high-performance and scalable parallel computing, emphasizing ease of use and expressiveness for distributed systems [1][2]. This article provides an overview of Chapel's syntax and usage for distributed computing and parallelism, as well as a comparison to CUDA.
## Chapel Syntax and Usage for Distributed Computing and Parallelism
Chapel simplifies the expression of parallel computation using `forall` loops, which automatically distribute work across available processors. The language also provides abstractions for data locality and distribution, such as domains and arrays that can be distributed over multiple locales (nodes). Special syntax for parallel reductions is built-in, ensuring safety and clarity when aggregating results across parallel tasks.
For instance, to perform a parallel reduction in Chapel, you would use the following syntax:
```chapel var sum = + reduce [i in 0..
- The Chapel programming language, designed for high-performance computing and scalable parallel tasks, simplifies the expression of parallel computation using loops, whose purpose is to distribute work across available technology, such as processors.
- In parallel with Chapel's ability to automatically distribute arrays over locales, it also offers a built-in syntax for parallel reductions, ensuring safety and clarity when aggregating results across multiple technology.
