Amesos2 transpose capability appears defunct
Created by: dridzal
I would like to use the transpose solve capability in @trilinos/amesos2 . After a few email exchanges with @srajama1 the conclusion is that this functionality may not work. For example, in Amesos2, in the file
test/solvers/KLU2_UnitTests.cpp
there is a line
amesos2_params.sublist("KLU2").set("Trans","TRANS","Solve with transpose");
If I look at KLU2, the "Trans"/"TRANS" pair is not allowed as an option. I get a runtime error. Similarly for the "Trans"/"CONJ" pair.
The parameter list validator suggests the "Transpose"/true(false) pair,
amesos2_params.sublist("KLU2").set("Transpose",true)
which doesn't throw an error, but also doesn't solve with the transpose.
The transpose capability is extremely important in numerical optimization. The @trilinos/rol team can create tests for it once available.
