TAU_TRACK_MEMORY_HEADROOM_HERE(3)
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();
