PROFILE

Ben Wibking

During March 2026, contributed to the modular/modular repository by delivering AMD CDNA2 architecture support in Mojo, specifically targeting the MI250X GPU. This work involved updating target configurations and ensuring compatibility across multiple subsystems, laying the groundwork for production-ready CDNA2 workloads. A smoke-test kernel workflow was implemented to validate kernel builds on the new target, following established MI300X patterns to enhance reliability. The development process emphasized compiler design, GPU programming, and performance optimization using Mojo, with a focus on robust test coverage, code quality, and adherence to contributor guidelines. No customer-reported bugs were addressed, as efforts centered on feature delivery.

March 2026 (2026-03) focused on expanding Mojo’s hardware support with a major feature delivery for the modular/modular repo. The team added AMD CDNA2 architecture support with a dedicated MI250X target, enabling enhanced GPU programming capabilities and broader hardware compatibility across Mojo components. The work included a targeted configuration update and associated compatibility work across subsystems, setting the foundation for CDNA2 workloads in production. A smoke-test style verification was added to validate kernel builds on the new target, aligning with MI300X patterns and ensuring reliability before broader adoption. No explicit customer-reported bugs were recorded this month; efforts were concentrated on feature delivery, test coverage, and quality controls. Overall, this month strengthened Mojo’s CDNA2 readiness, reduced risk for future AMD-generation targets, and positioned the project to support customers deploying MI250X-based workflows.
