Windows DLL available?

Dear Mr.Chen,
do you have a windows dll compiled?
We'd like to try out CKTSO-GPU.
Best regards,
Geri

Thank you, it's working. I tried it on a GEForce RTX 3070 Ti.
Refact. and Solve looks slower than on CPU, it's a Ryzen 9 7950.
System monitor shows GPU usage well.

With demo benchmark program it's much slower- see attached screens.
Do you know how we can improve it? Linux could work better? What is you experience?

This matches expected. Add20 is a very small and sparse case. The GPU module can only accelerate matrices which are large and slightly dense, like those matrices from large-scale circuit post-layout simulations. You can try other matrices like g2_circuit, twotone, etc.
Though GPU acceleration for sparse solvers itself is an extremely hard problem, I will try to improve this library by using some new ideas.
