<div class="orbitron"><font size="+1">System Overview:</font></div>''EJFAT is a collaboration between Energy Sciences Network (ESnet) and Thomas Jefferson National Laboratory (JLab) for proof of concept engineering to program a Field Programmable Gate Array (FPGA) for network data routing of commonly tagged UDP packets from any data source to individual and configurable destination endpoints in an end-point compute work load balanced manner, including some additional tagging for stream reassembly at the endpoint. The primary purpose of this FPGA based acceleration is to load balance work to destination compute farm endpoints with low latency and full line rate bandwidth of 100 Gbs with feedback from the destination compute farm.

<div class="orbitron"><font size="+1">System Overview:</font></div>''EJFAT is a collaboration between Energy Sciences Network (ESnet) and Thomas Jefferson National Laboratory (JLab) for proof of concept engineering for accelerated load balancer (LB) using dynamic IP4/6 address forwarding. Dynamic because the forwarding address is chosen dynamically from a collection of destination endpoints based on near real-time destination workload conditions, and accelerated because the forwarding is accomplished with low fixed latency at line rates of up to 200Gbps per FPGA, where in general a functioning LB may consist of up to four FPGAs acting as one logical DP for a total bandwidth capacity of over 1 Tbps. The low, fixed latency is achieved by utilization of an appropriately programmed Field Programmable Gate Array (FPGA) to effect the Data Plane (DP) functions of the LB.

Welcome to the EJFAT Wiki

(ESnet / JLaB FPGA Accelerated Transport)


System Overview:

EJFAT is a collaboration between Energy Sciences Network (ESnet) and Thomas Jefferson National Laboratory (JLab) for proof of concept engineering for accelerated load balancer (LB) using dynamic IP4/6 address forwarding. Dynamic because the forwarding address is chosen dynamically from a collection of destination endpoints based on near real-time destination workload conditions, and accelerated because the forwarding is accomplished with low fixed latency at line rates of up to 200Gbps per FPGA, where in general a functioning LB may consist of up to four FPGAs acting as one logical DP for a total bandwidth capacity of over 1 Tbps. The low, fixed latency is achieved by utilization of an appropriately programmed Field Programmable Gate Array (FPGA) to effect the Data Plane (DP) functions of the LB.

  1. Price Estimate Spreadsheet
  2. Networking Diagram, Updated (PDF) (from Brent 2024-02-09)
  3. PR408549 : Requisition 1 of 2 :
    1. Statement of Work for Servers
    2. 1/13/2022: EJFAT team decided to solicit two bid responses, one with MLX NIC and one without. Response from Procurement is "I can ask for the two separate quotes. If you are going to purchase both option (with & without add-in cards), once I receive the quotes back, you will have submit a new PR to cover the option (without add-in cards)."
    3. 1/18/2022: Question from KOI Computers: "please clarify what the part number for the NVIDIA Dual Port ConnectX-6". Replied with part # MCX623106AN-CDAT.
    4. 1/24/2022: Requisition currently open for bid responses from vendors. Due date is COB 1/24/2022.
    5. 1/27/2022: PO awarded to Atipa for 6 servers and 1 file-server with FPGA and MLX SmartNIC. Expected delivery date from vendor is 5/31/2022.
