NAME¶
hwlocality_gl - Interoperability with OpenGL displays
SYNOPSIS¶
Functions¶
static hwloc_obj_t
hwloc_gl_get_display_osdev_by_port_device (hwloc_topology_t
topology, unsigned port, unsigned device)
static hwloc_obj_t hwloc_gl_get_display_osdev_by_name
(hwloc_topology_t topology, const char *name)
static int hwloc_gl_get_display_by_osdev (hwloc_topology_t
topology, hwloc_obj_t osdev, unsigned *port, unsigned *device)
Detailed Description¶
This interface offers ways to retrieve topology information about OpenGL displays.
Only the NVIDIA display locality information is currently available, using the NV-CONTROL X11 extension and the NVCtrl library.
Function Documentation¶
static int hwloc_gl_get_display_by_osdev (hwloc_topology_t topology, hwloc_obj_t osdev, unsigned * port, unsigned * device) [inline], [static]¶
Get the OpenGL display port and device corresponding to the given hwloc OS object. Retrieves the OpenGL display port (server) in port and device (screen) in screen that correspond to the given hwloc OS device object.
Returns
-1 if none could be found.
The topology topology does not necessarily have to match the current machine. For instance the topology may be an XML import of a remote host. I/O devices detection and the GL component must be enabled in the topology.
static hwloc_obj_t hwloc_gl_get_display_osdev_by_name (hwloc_topology_t topology, const char * name) [inline], [static]¶
Get the hwloc OS device object corresponding to the OpenGL display given by name.
Returns
NULL if none could be found.
The topology topology does not necessarily have to match the current machine. For instance the topology may be an XML import of a remote host. I/O devices detection and the GL component must be enabled in the topology.
Note
static hwloc_obj_t hwloc_gl_get_display_osdev_by_port_device (hwloc_topology_t topology, unsigned port, unsigned device) [inline], [static]¶
Get the hwloc OS device object corresponding to the OpenGL display given by port and device index.
Returns
NULL if none could be found.
The topology topology does not necessarily have to match the current machine. For instance the topology may be an XML import of a remote host. I/O devices detection and the GL component must be enabled in the topology.
