NVIDIA Rivermax SDK

Performance Boost

Minimal dependency on CPU strength—frees up CPU cycles for application usage.

Powerful & Flexible SDK

Unified streaming SDK glues together the NIC and GPU to enable interconnect, orchestration, and SMPTE ST 2110 specification compliance.

Right On Time

It’s all about timing—utilizing ConnectX or the DPU family of nano-seconds accurate PTP.

• Kernel bypass technology – Hardware-based direct copy between an application’s user-space memory and the network interface
• Packet handling offloads by hardware
• GPUDirect—zero memory copy to GPU, reducing PCIe transactions, CPU usage, jitter and latency
• Hardware packet pacing for any data stream
• Single CPU core receives or sends 8 UHD 2160p60 or 32 FHD 1080p60 streams
• Performance scales linearly both in terms of CPU loading and network bandwidth

Rivermax’s GPUDirect utilizes the high speed PCIe interface to pass the data directly to and from the GPU without burdening the CPU cores

• Rivermax with GPUDirect supports 8 streams of UHD 2160p60 with one CPU Core
• Saves CPU cycles and increases GPU processing capacity
• Zero Memory Copy to/from GPU
• 65% CPU reduction (for 10Gbps)
• Reduces PCIe transactions
• Reduces PCIe transactions
• Cuts processing latency
• Less CPU Cores = Lower overall power requirements
• Supported on Linux and Windows

The novelty of RoCE/RDMA UDP/IP Multicast for media and data streaming
