NAME¶
TAU_TRACK_MEMORY - Initializes memory tracking system
SYNOPSIS¶
C/C++:
TAU_TRACK_MEMORY(void);
Fortran:
TAU_TRACK_MEMORY(void);
DESCRIPTION¶
For memory profiling, there are two modes of operation: 1) the user explicitly inserts TAU_TRACK_MEMORY_HERE() calls in the source code and the memory event is triggered at those locations, and 2) the user enables tracking memory by calling TAU_TRACK_MEMORY() and an interrupt is generated every 10 seconds and the memory event is triggered with the current value. Also, this interrupt interval can be changed by calling TAU_SET_INTERRUPT_INTERVAL(value). The tracking of memory events in both cases can be explictly enabled or disabled by calling the macros TAU_ENABLE_TRACKING_MEMORY() or TAU_DISABLE_TRACKING_MEMORY() respectively.
EXAMPLE¶
C/C++ :
TAU_TRACK_MEMORY();
Fortran :
call TAU_TRACK_MEMORY()
