Description
The AMGX becomes very slow at the stage
"Parsing configuration string: selector=AGGRESSIVE_PMIS " after I increased the matrix size (matrix B). The dimension of matrix are as follows:
A: NumGlobalRows 7921 NumGlobalNonzeros 745121
B: NumGlobalRows 12321 NumGlobalNonzeros 1687841
For A, it is fast. but for B it is very slow .
Do I have some method to increase this setup process.
I have tried to change the selector to "SIZE_2" , but the systems feedback the infors " the selector is not well for this matrix"
Regards

Research direction
Begin by reproducing the AMGX setup stage for the reported A and B matrix dimensions, focusing on the configuration string with selector=AGGRESSIVE_PMIS. Compare it with the attempted SIZE_2 selector and determine whether the project documents a supported way to reduce setup time; done means explaining the difference or identifying a validated configuration change.
