UCX

UCX refers to a family of high-performance communication frameworks developed by NVIDIA. Its primary purpose is to accelerate the movement of data between different hardware accelerators, such as GPUs and CPUs, and across nodes in a cluster. UCX is designed to be a flexible and efficient solution for distributed computing applications, particularly in the fields of artificial intelligence, machine learning, and high-performance computing. It provides a unified API that abstracts away the complexities of underlying network interconnects like InfiniBand, Ethernet, and shared memory. This allows developers to write applications that can run efficiently on various hardware configurations without significant code changes. The framework is optimized for low latency and high bandwidth, crucial for scaling applications across multiple processors and machines. UCX supports various communication patterns, including point-to-point and collective operations, and integrates with popular deep learning frameworks and HPC libraries. Its modular design allows for easy extension and customization to meet specific application needs.
