Support for unified memory across CPUs and GPUs in accelerated computing systems is the final piece of a programming puzzle that we have been assembling for about ten years now. Unified memory has a ...

Suppose for a moment that you're an engineer designing a new 8051-based product. Not unexpectedly, the application's code size will greatly exceed the 64KB architectural limit of the 8051's program ...

Write program to run in parallel? Yes. Did you remember to use a Scalable Memory Allocator? No? Then read on … In my experience, making sure “memory allocation” for a program is ready for parallelism ...

Intel Xeon Phi processors have two features that I believe we will see in more and more designs for HPC systems in the future: high bandwidth memory, and options for subdividing the many cores into ...

High Bandwidth Memory (HBM) is the commonly used type of DRAM for data center GPUs like NVIDIA's H200 and AMD's MI325X. High Bandwidth Flash (HBF) is a stack of flash chips with an HBM interface. What ...

The C language has been a programming staple for decades. Here’s how it stacks up against C++, Java, C#, Go, Rust, Python, and the newest kid on the block—Carbon. The C programming language has been ...
