Exporting Topologies to Synthetic

Enumerations

enum  hwloc_topology_export_synthetic_flags_e { HWLOC_TOPOLOGY_EXPORT_SYNTHETIC_FLAG_NO_EXTENDED_TYPES, HWLOC_TOPOLOGY_EXPORT_SYNTHETIC_FLAG_NO_ATTRS }

Functions

int hwloc_topology_export_synthetic (hwloc_topology_t topology, char *buffer, size_t buflen, unsigned long flags)

Enumeration Type Documentation

Flags for exporting synthetic topologies.

Flags to be given as a OR'ed set to hwloc_topology_export_synthetic().

Enumerator:
HWLOC_TOPOLOGY_EXPORT_SYNTHETIC_FLAG_NO_EXTENDED_TYPES 

Export extended types such as L2dcache as basic types such as Cache.

This is required if loading the synthetic description with hwloc < 1.9.

HWLOC_TOPOLOGY_EXPORT_SYNTHETIC_FLAG_NO_ATTRS 

Do not export level attributes.

Ignore level attributes such as memory/cache sizes or PU indexes. This is required if loading the synthetic description with hwloc < 1.10.


Function Documentation

int hwloc_topology_export_synthetic ( hwloc_topology_t  topology,
char *  buffer,
size_t  buflen,
unsigned long  flags 
)

Export the topology as a synthetic string.

At most buflen characters will be written in buffer, including the terminating .

This exported string may be given back to hwloc_topology_set_synthetic().

flags is a OR'ed set of hwloc_topology_export_synthetic_flags_e.

Returns:
The number of characters that were written, not including the terminating .
-1 if the topology could not be exported, for instance if it is not symmetric.
Note:
A 1024-byte buffer should be large enough for exporting topologies in the vast majority of cases.
