Dec 1, 2025December 2025 accomplishments focused on Kunlun backend operator support and test infrastructure improvements in InfiniCore. Key features delivered include Kunlun backend support for Softplus and GELU elementwise operations, with a new Softplus backend kernel and descriptor files, plus a GELU kernel integrated with elementwise execution across multiple data types. In addition, test infrastructure improvements in topkrouter refactored a test function to remove an unnecessary synchronization call, boosting code clarity and runtime performance. Impact includes broader Kunlun device coverage for core arithmetic ops, faster validation cycles, and more maintainable test suites. Technologies demonstrated include backend kernel development, descriptor-driven op definitions, cross-backend integration, and Python test refactoring for performance optimization.
