    SQL Analytics at GPU Speed

    Sirius is a GPU-native SQL engine. It plugs into existing databases such as DuckDB via the standard Substrait query format, requiring no query rewrites or major system changes. By offloading query execution to GPUs, Sirius achieves over 10× speedup at the same hardware rental cost!
