# TAU\_TRACK\_MEMORY(3)

Initializes memory tracking system

## 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()
```
