52 This will provide a summary of the bandwidth with different number of MPI
70 uses a different memory bus:
121 evolving and compilers on different machines were not identical. Using C function pointers
139    - We employ continuous integration testing of the entire PETSc library on many different
186      sequential; you don't call a different routine for each format.
197 ### How come when I run the same program on the same number of processes I get a "different" answer?
200 different runs the order at which values arrive at a given process (via MPI) can be in a
201 different order, thus the order in which some floating point arithmetic operations are
202 performed will be different. Since floating point arithmetic is not
203 associative, the computed quantity may be slightly different.
210 The discussion above assumes that the exact same algorithm is being used on the different
211 number of processes. When the algorithm is different for the different number of processes

1306 ### How does PETSc's `-help` option work? Why is it different for different programs?
1322 root rank**. Different programs may take different paths through PETSc source code, so
1323 they will encounter different providers, and therefore have different `-help` output.

2136 different `$PETSC_ARCH` for this build so you can easily switch between the two).
