This table summarizes the options that may be passed to the
{\tt ESMF\_TimerInit} call.  Each option takes an associated value of
either 1 (true/enable) or 0 (false/disable).

\begin{tabular}{lll}
{\tt \bf Option} & {\tt ESMF\_RESERVED[\#]} & Not to be used.  Reserve values for library. \\
                 & {\tt ESMF\_USRSYS} & (Tracks/reports) Unix user and system time.  \\
                 & {\tt ESMF\_WALL} & Wall clock time (absolute run-time).  \\
                 & {\tt ESMF\_LD1CACHE\_MISS} & Level 1 cache misses.  \\
                 & {\tt ESMF\_LD2CACHE\_MISS} & Level 2 cache misses.  \\
                 & {\tt ESMF\_CYCLES} & Cycles spent in process/(thread).  \\
                 & {\tt ESMF\_ELAPSED\_CYCLES} & Total cycles spent (all processes).  \\
                 & {\tt ESMF\_FP\_INSTR} & Floating point operations. \\
                 & {\tt ESMF\_LOADSTORE\_INSTR} & Load and store operations. \\
                 & {\tt ESMF\_INSTR} & Sum of all completed instructions. \\
                 & {\tt ESMF\_STALL} & Sum of all cycles the process/(thread) is stalled. \\
