What preprocessing methods are supported for PCG

[Yangshen-bot]

I learned from AMGX_ Conference that PCG currently supports several preprocessing methods as shown in the figure. I would like to know if other preprocessing methods are also supported, such as SSOR or diagonal preprocessing. The reason why I am asking this is because several preprocessing methods currently seem to have not been very helpful for my problem.

Just sharing a bit of my experience. You can directly do it on the raw data by yourself before upload to AMGX's matrix object.
