As of August 2022, Grid'5000 features 2 nodes, each equipped with one AMD/Xilinx FPGA.
Hardware description
The Grenoble site of Grid'5000 hosts 2 servers (Servan cluster) equipped with an AMD/Xilinx FPGA. FPGA are AMD/Xilinx Alveo U200, which are PCIe Accelerator card.
Detailed specifications are provided here (cards with passive thermal cooling).
Technically, the installation of those FPGAs in the Servan nodes has the following characteristics:
- JTAG
- JTAG programming is provided on Xilinx Alveo U200 via a USB port on the card. In the Grid'5000 configuration, it is cabled back to hosting machine itself. Thus, programming of the FPGA of e.g. servan-1 can be done (e.g. with Vivado) from e.g. servan-1 itself.
- Network
- Both Ethernet ports of the FPGA are cabled to the site network along with all servers of the site (including the servan server NICs).
- Ethernet ports are not shown as NICs in the operating system of the hosting machine (unless FPGA is programmed as to do so).
- Ethernet ports are cabled to 100Gbps ports on Grenoble site router/switch. Switch ports are configured with Auto-Negotiation disabled and Speed forced to 100Gbps (not working otherwise, as far as we tested).
- Kavlan is supported on the FPGA Ethernet ports just like any NIC of a server of the site (including the servan servers NICs). FPGA ports are named servan-1-fpga0, servan-1-fpga1, servan-2-fpga0, servan-2-fpga1 in kavlan. IP addresses are provided via DHCP to the FPGA ports in kavlan where the DHCP service is available.
- Note: using the 100Gbps capability of the FPGA ports requires acquiring a free of charge Xilinx licence.
- Wattmetre
- The servan cluster is monitored by a wattmeter, providing the energy consumption of each server, including the FPGA.
- Energy consumption can also be retrieve using Xilinx tools (e.g. xbutil, xbtop)when FPGA are used with XRT (see below).
