TAU_TRACK_MEMORY_HEADROOM_HERE

NAME

TAU_TRACK_MEMORY_HEADROOM_HERE - Takes a sample of the amount of memory available at a given point.

SYNOPSIS

C/C++:

TAU_TRACK_MEMORY_HEADROOM_HERE(void);

Fortran:

TAU_TRACK_MEMORY_HEADROOM_HERE(void);

DESCRIPTION

Instead of relying on a periodic interrupt to track the amount of memory available to grow, this call may be used to take a sample at a given location in the source code. Context events are used to track the amount of memory headroom.

EXAMPLE

C/C++ :

 ary = new double [1024*1024*50];
 TAU_TRACK_MEMORY_HEADROOM_HERE();
     
 

Fortran :

 INTEGER, ALLOCATABLE :: STORAGEARY(:)
 allocate(STORAGEARY(1:999), STAT=IERR)
 TAU_TRACK_MEMORY_HEADROOM_HERE();
