+
+By default, SMPI benchmarks computational phases of the simulated application (i.e., CPU bursts in
+between MPI calls) so that these phases can be simulated. In some cases, however, one may wish to
+disable simulation of application computation. This is the case when SMPI is used not to simulate
+an MPI applications, but instead an MPI code that performs "live replay" of another MPI app (e.g.,
+ScalaTrace's replay tool, various on-line simulators that run an app at scale). In this case the
+computation of the replay/simulation logic should not be simulated by SMPI. Instead, the replay
+tool or on-line simulator will issue "computation events", which correspond to the actual MPI simulation
+being replayed/simulated. At the moment, these computation events can be simulated using SMPI by
+calling internal smpi_execute*() functions.
+
+To disable the benchmarking/simulation of computation in the simulated application via this runtime automatic
+switching, the variable \b smpi/privatize_global_variables should be set to no
