Sipeed s 4A Cluster

 

Lichee Cluster 4A (hereinafter referred to as LC4A) is a high-performance RISC-V cluster computing platform developed by SiliconSpeed Technology. It can be used to build multi-node computing clusters, and can also learn Kubernetes, automation, edge artificial intelligence computing, local mini servers, and hosted applications. Excellent tool for programs, containers, etc. A single Lichee Cluster 4A can be equipped with up to 7 LM4A core boards. Each LM4A core board contains an NPU with 4TOPS@int8 AI computing power. A single core board supports up to 16GB LPDDR4X memory and 128G eMMC storage. The entire cluster has strong flexibility and reliability. Scalability.

 

Lichee Cluster 4A has an onboard eight-port Gigabit switch to provide high-speed connections and easily connect multiple nodes to form a powerful computing cluster. It also supports USB3.0 and SD card storage expansion, making it easy to expand additional storage or add peripherals. equipment.

 

Lichee Cluster 4A also comes with BMC (out-of-band management), which independently connects the system serial port and reset pin of each LM4A. BMC can reset a single computing node from the hardware, and can also execute commands through the serial port, such as executing ser2net or kermit to manage slots.

3.2. Motherboard frame diagram

lc4a_architecture

 

LicheeRV SOM (D1 C906@1GHz) has 5 native serial ports and two USB serial ports, which are independently connected to 7 SOMs.

 

Each LM4A's RST/BOOT can be controlled via an analog switch.

 

LM4A No. 1 has the second Gigabit port and HDMI port by default, which facilitates the SOM to perform task distribution operations for the entire cluster.

 

The motherboard can be powered by a 12V DC charging head (12V9A or above recommended), or by a standard ATX power supply.

3.3. Chassis introduction

 

It is recommended to choose the MINI-ITX chassis. This chassis has good appearance and heat dissipation performance, and is convenient for the deployment and display of computing clusters.

 

The chassis is adapted to the MINI-ITX motherboard, equipped with a 250W high-power power supply, and installed with a 12cm silent fan for heat dissipation, which can ensure that the CPU temperature is below 70 degrees when running at full load.

3.4. Hardware Installation Guide

 

By default, all SOMs have been installed on the LC4A during transportation. If you need to remove or upgrade the SOM, please refer to the following instructions.

3.4.1. Install core board

 

Pull the white lock buckle to both sides. Please confirm the gap before inserting to avoid damage caused by incorrect direction.

3.4.2. Install BMC

Install the burned image SD card to LicheeRV, then install the LicheeRV module to the seat next to the switch chip, and then tighten the screws.

3.4.3. Plug in power

Optional ATX power supply or DC movie power supply.

 

Make sure the buckle of the ATX power socket is fastened to avoid poor contact causing the connector to heat up.
