Hi,

Is there documentation someplace which tells me the details of the Barrier CPLEX log when the barDisplay is set to detailed (Diagnostic) output?

BarDisplay = 2

Like for example, what does the histogram of super-node widths mean?

Did you check this section in the user manual?

Yes I did. It gives me an overview in a very limited detail.

But it doesn't describe anything that we see in the detailed diagnotic output when we set the variable Bardisplay = 2.

The "Histogram of super-node widths" has to do with the parallel Cholesky factorization. If you search the internet for "parallel Cholesky factorization supernode" you will find papers on this, for example this one: http://www-users.cs.umn.edu/~agupta/doc/direct.pdf
