Imagine writing parallel code that can run on any platform - CPUs, GPUs, DPUs, specialized accelerators, etc - without any language or vendor extensions, external libraries, or special compilation tools. It’s no longer just a dream - you can do it today in Standard C++!
Parallelism is increasingly common in software, from supercomputer simulations to mobile applications. But writing parallel code is increasingly challenging due to an explosion of diversity in hardware, a trend that’s likely to continue into the future. To meet this challenge, the C++ Committee has developed C++ Standard Parallelism, a parallel programming model for Standard C++ that is portable to all platforms, from your smartwatch to your supercomputer, and delivers reasonable performance and efficiency for most use cases.
Our vision of C++ Standard Parallelism consists of three key components:
- Common parallel algorithms that dispatch to vendor-optimized parallel libraries
- Tools to write your own parallel algorithms that run anywhere.
- Mechanisms for composing parallel invocations of algorithms into task graphs.
In this talk, we’ll dive into the roadmap for C++ Standard Parallelism - we’ll discuss what we already have that you can use today, what’s coming down the line, and where the future may lead us.
