Constraint Overview

Usage: add constraint to any job allocation (srun, sbatch, salloc) in the FPGA partition where you plan to execute a design on the designated FPGA cards.

e.g. srun --partition=fpga --constraint=xilinx_u280_xrt2.12 -A [YOUR_PROJECT_ACCOUNT]

1 Xilinx Alveo U280 Nodes
2 Intel Stratix 10 Nodes
3 Emulation

Xilinx Alveo U280 Nodes

Each node has 3 Xilinx Alveo U280 cards.

--constraint=

--constraint=
`xilinx_u280_xrt2.16`	Configured with XRT 2.16 drivers and usable for designs built with Vitis 23.2 and Shell xdma_202211_1
`xilinx_u280_xrt2.15` `xilinx_u280_xrt2.14` `xilinx_u280_xrt2.13` `xilinx_u280_xrt2.12` `xilinx_u280_xrt2.11` `xilinx_u280_xrt2.8`	Further constraints named by xrt version. Refer to Xilinx Vitis, XRT and U280 shell version combinations

Intel Stratix 10 Nodes

Each node has 2 Bittware 520N cards.

--constraint=

--constraint=
`bittware_520n_20.4.0_max`	Configured with BSP 20.4.0_max with external channels enabled.
`bittware_520n_20.4.0_hpc`	Configured with BSP 20.4.0_hpc with external channels disabled.
`bittware_520n_19.4.0_max` `bittware_520n_19.4.0_hpc` `bittware_520n_19.2.0_max` `bittware_520n_19.2.0_hpc` `bittware_520n_19.1.0_max` `bittware_520n_18.1.1_max` `bittware_520n_18.1.1_hpc`	Further constraints named by BSP version. Refer to Intel oneAPI versions and Bittware BSP version combinations and Intel FPGA SDK for OpenCL and Bittware BSP version combinations

Emulation

Emulation works on all Noctua2 nodes. For the FPGA partition, it’s mandatory to specify a constraint. With the emulation constraint, you state that you don’t rely on any specific FPGA shell or device driver to be active.

--constraint=

--constraint=
`emul`	Emulation only if you use the FPGA partition, but do not use the FPGA cards.
