TAU_TRACK_MEMORY_HEA(3) TAU Instrumentation API TAU_TRACK_MEMORY_HEA(3)

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();
