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();

Fortran:

TAU_TRACK_MEMORY_HEADROOM_HERE();

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();
    

Python:

import pytau

pytau.trackMemoryHeadroomHere()
