General FAQ

Rivermax is a licensed closed-source library. An SDK is provided which includes example reference code and the API layer.

Rivermax supports Linux, Windows and Containerized/Virtualized environments like VMware and OpenStack. Rivermax can run on x86 or Arm architectures. ConnectX-6 Dx and Bluefield-2 are the main supported platforms.

The Rivermax SDK can be used by any data streaming application. Rivermax provides very high bandwidth, low latency, GPU-Direct and zero memory copy. Applications that need to support IP-Enabled TV Studio Media (SMPTE ST 2110) is a good example use case for the Rivermax SDK. Some popular use cases are: video broadcasting, video wall-display, high BW camera ingest, retail camera input analytics, healthcare DICOM-RTV and H264/5 compressed data.

Yes. Using Rivermax, each frame must be committed with a time parameter set to a system time value (in nanosecond resolution) stating when it must be sent. The system time gets synchronized to a PTP GrandMaster using third party software. PTP time synchronization is supported for Linux, Windows over bare metal and virtualized environments.
Rivermax version 1.8 introduces accurate timing for Windows and virtualized environments using the BlueField-2 DPU.

Yes. Rivermax supports GPU-Direct over Ethernet IP/UDP.
This solution is highly optimized to move data between the NIC and the GPU directly without CPU intervention nor the need to transfer it via host memory.
Rivermax supports splitting and reconstructing headers and payload. This can be used to place headers in host memory while placing only the payload in GPU memory should an application choose to do so.
This enables having the payload contiguous in GPU memory and at the same time reduces CPU processing to a minimum.
GPU-Direct is supported on Linux and beginning with Rivermax version 1.8 on Windows.

Rivermax is “JT-NM Tested”. It has been tested for SMPTE ST 2110-20/30/40, 2022-7 compliance. Rivermax also supports ST2022-6 and ST 2110-31. The full report can be downloaded from the JT-NM.org:
