Deliver Uncompromised Performance across Diverse Workloads Using These Developer Resources

You’ve probably heard the buzz about oneAPI, an industry initiative to create a single, unified, heterogeneous programming model to simplify coding for CPU, GPU, FPGA and AI architectures. The oneAPI initiative is based on an open specification and standards to encourage multi-vendor adoption.

Alongside the initiative, Intel has developed a reference implementation of oneAPI with a set of with a set of toolkits (currently in beta) to address the growing and diverse needs of data-centric workloads.

Like any other new technology and approach, developers almost certainly will have questions about oneAPI: how to get it, how to use it, what its full capabilities are, who’s supporting it … the list goes on.

What follows is a roundup of oneAPI resources, designed to help you get started and build skills simplifying your cross-architecture programming efforts.

Answering a Compelling Need for Heterogeneous Computing

Today, most performance-driven programming is targeted to single architectures and doesn’t easily allow for code to be reused on other architectures. This limits choice and makes development inefficient, time-intensive, and costly.

What's inside Intel oneAPI Base ToolkitAs time-constrained developers well know, no single architecture is best for every workload. They require a mix of scalar, vector, matrix, and spatial (SVMS) architectures deployed in CPU, GPU, FPGA, and other accelerators.

That’s where Intel oneAPI products come in: delivering the tools needed to deploy applications and solutions across those SVMS architectures. This set of toolkits—a base kit and specialty add-ons—simplify programming and help developers improve efficiency and innovation.

These oneAPI resources will help you get started with a heterogeneous approach to programming for diverse architectures:
