But then people have dead environmental variables hanging around for years they forget about.
This is exactly why we turn off environmental variables in PETSc ./configure because so many people have crap in there they don't even know about.

(The error message was garbled for some reason, which slowed things down. As soon as I saw "%-pc_type_hypre" I knew what the problem was.) As you can see below he spent a day doing this.

The error messages showed "Unknown statement in options file: (%-pc_type hypre )" even though my petsc.rc doesn't have that line. I checked petsc.rc files in XGC source file directory as well as working(running) directory, but that line doesn't exist. Also the default .petscrc doesn't exist in both directories. It seems Petsc is looking at a certain directory, but cannot check where it is.

Considering "invalid argument" in the message, I guess the petsc.rc included in the xgca_chang-hinton_test.tar doesn't work. Unfortunately, the characters for the unknown option shown in the message is broken. Do you have working petsc.rc?

Making the collision time step variable is a bit complicated because the collision operation is usually run together with all other sources like heating, etc. Therefore, the distribution function is evaluated only every sml_f_source_period time steps. If a collision operation is supposed to run at a different time step, f will not be available with the current code. However, in order to test whether it is worth to pursue this approach, I wanted to implement variable collision time steps in the simplest possible way, i.e. sml_f_source_period=0 and all sources except the collision operation deactivated. The collision interval must have an upper limit which I set to 10 time steps in my test. The interval for load-balancing should be a multiple of this upper limit in order to be efficient. If this approach helps to improve performance, we can think about how to implement variable collision intervals in a cleaner way.
