Release 27.2000.2046 |
|
|
NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) |
[Beta] NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) technology improves the performance of MPI operations by offloading collective operations from the CPU to the switch network, and by eliminating the need to send data multiple times between endpoints. |
|
Link Speed |
Added QDR/FDR support in Quantum switch systems when using optical cables of up to 30m. Note: QDR speed is only supported when using the FDR cables. See Validated and Supported FDR Cables |

|
Release 27.2000.1004 |
|
|
Link Speed |
Stability improvements for HDR link. |
|
Subnet Manager (Adaptive Routing) |
Added support for Adaptive Routing. Adaptive routing (AR) allows optimizing data traffic flow. The InfiniBand protocol uses multiple paths between any two points. Thus, when unexpected traffic patterns cause some paths to be overloaded, AR can automatically move traffic to less congested paths according to the current temporal state of the network. |
|
Adaptive Routing |
Added support for Private Linear Forwarding Tables (PLFT). This capability helps SM to optimize traffic. |
