## Summary

AMD has released the ROCm HRX Loom SDK, a specialized compiler and intermediate representation (IR) stack as part of its ROCm advancements. Loom compiles kernels and asynchronous device programs, links model programs, and specializes them for execution on AMD CPUs, GPUs, and NPUs. It supports AMDGPU HSA emission for GPU execution, SPIR-V/Vulkan for portable execution, and x86 and WebAssembly, though the latter is still maturing.

The Loom SDK includes a compiler, runtime, Python APIs, and command-line tools. Users can install models and assets via `loom-fetch` and serve requests over HTTP with `loom-serve`. The first tagged release of Loom is now available on GitHub and can be installed via Python’s `pip` as the `hrx-loom` package. AMD describes Loom as part of its broader ROCm HRX system, aimed at agentic workload optimizations.

## Key points

- Loom SDK compiles and specializes programs for AMD CPUs, GPUs, and NPUs
- Supports AMDGPU HSA, SPIR-V/Vulkan, x86, and maturing WebAssembly
- Available via GitHub and Python’s pip as `hrx-loom` package

## Why it matters

Loom expands AMD’s ROCm ecosystem, enabling developers to optimize workloads across AMD’s hardware stack, potentially accelerating AI and HPC applications.
