NDR InfiniBand host-channel adapters (HCAs) with PCIe Gen4 and Gen5 support various form factors, delivering single or dual network ports at 400 gigabits per second (Gb/s) for NDR, 200 Gb/s for NDR200, and lower speeds.
The NDR InfiniBand HCAs include advanced In-Network Computing capabilities with MPI All-to-All and MPI Tag Matching hardware engines and other fabric improvements for enhanced quality of service (QoS), including adaptive routing, congestion control, and more. The HCAs also include programmable compute cores, which enable offloading pre-processing data algorithms and application control paths to the network, providing higher performance, scalability, and enhance overlapping between compute and communication.
