Sextans is an accelerator for general-purpose Sparse-Matrix Dense-Matrix Multiplication (SpMM). One exciting feature is that we only need to prototype Sextans once, and the hardware supports an arbitrary SpMM. Following are software and hardware dependencies.
- Xilinx Vitis 2020.2
- Alveo U280 HBM FPGA
- Alveo U250 FPGA
