The Future of Render Farms: Leveraging GPU Expansion for Greater Efficiency
GPU technology is advancing rapidly, and businesses that leverage GPU expansion in their render farms are better positioned to meet future demands. From real-time rendering to AI-driven content creation, GPU expansion can effectively improve the efficiency of render farms.
The OpenCloudOS Community Welcomes A New Member - LR-LINK
Recently, Linkreal Co., Ltd (hereinafter called LR-LINK), as a deep cultivator in the board industry, signed CLA (Contributor License Agreement) and officially became a member of the OpenCloudOS community. This action marks an important step taken by LR-LINK in deepening industry cooperation and promoting open sharing of technology, and opens a new chapter for LR-LINK to work with developers to create an open source ecosystem.

Increasing growth in 5G RAN and edge deployments is driving demand for high-precision timing synchronization across the network. Meet these challenging requirements head-on with a standards-based PCIe adapter that provides greater flexibility at a lower price point than single-purpose timing appliances.Most 5G RAN deployments use 1588 PTP, SyncE, or both to ensure required timing synchronization.The LRES6080PF-SFP28 TimeSync card is based on the Intel E810 NIC controller and Microchip PLL and supports 4 port of 25/10/1GbE . It uses 1PPS and 10MHz to synchronize the host
system with an external clock source, and supports both 1588v2/PTP and SyncE synchronization methods. It achieves high clock accuracy in master and slave modes, while additional hardware enhancements ensure reliability and accuracy, and provide greater flexibility and simplicity for timing synchronization deployments.
Main features
Clock synchronization:
- Quad-port SFP28 for 25G/10GbE
- Supports PTP Transparent Clock (TC) Boundary Clock (BC) OC (Master/Slave)
- IPv4 (IEEE-1588v2)/SyncE based PTP
- GNSS integration supports frequency, phase and time synchronization with GNSS systems
- 10Mhz and 1PPS outputs for measurements
- Complete hardware and software time synchronization solution based on industry-leading DPLL, servo stack and PTP1588
- Integrated precision OCXO +/-5ppb for long term retention < 1.5us over 4 hours without physical layer assistance
LAN and virtualization capabilities:
- RDMA: iWARP and RoCEv2 support, selectively configurable for each port.
- SR-IOV (Single Root I/O Virtualization): 8pf, 256VFs, 768vsi, 256 queues/ PF, 2K queue pairs
- DPDK: Supports advanced packet forwarding and efficient packet processing
