29 ///< the maximum number of nodes supported
95  * \brief Obtains the maximum number of nodes the system can handle
97  * \return maximum nodes supported
108  * \brief Obtains the number of all memory nodes in the system
110  * \return number of memory nodes in the system
112  * returns the number of memory nodes in the system. This count includes any nodes
118  * \brief obtains the nodes the domain is allowed to allocate memory from
120  * \returns bitmask representing the allowing nodes
122  * returns the mask of nodes from which the process is allowed to allocate memory
138  * \brief bitmask that is allocated by the library with bits representing all nodes
162  * \brief returns the number of nodes on which the calling domain is allowed to
165  * \returns number of nodes the domain is allowed to use
185  * \brief parses a character string list of nodes into a bit mask.
249  * fall back to other nodes if no memory is available on the the preferred node
268  * \param nodemask bitmask representing the nodes
270  * All new memory allocations are page interleaved over all nodes in the interleave
273  * This bitmask is considered to be a hint. Fallback to other nodes may be possible
278  * \brief binds the current task and its children to the nodes specified in nodemask.
280  * \param nodemask  bitmap representing the nodes
292  * \param nodemask  bitmap representing the nodes
294  * The task will only allocate memory from the nodes set in nodemask.
296  * an empty mask or not allowed nodes in the mask will result in an error
301  * \brief returns the mask of nodes from which memory can currently be allocated.
303  * \return bitmap of nodes from which can be allocated
335  * \brief allocates size bytes of memory page interleaved on all nodes.
348  * \brief allocates size bytes of memory page interleaved the nodes specified in
352  * \param nodemask subset of nodes to consider for allocation
442  * Passing -1 permits the kernel to schedule on all nodes again
447  * \brief runs the current domain only on nodes specified in nodemask.
449  * \param nodemask bitmap representing the nodes to run the domain on
477  * s a flag that says whether the functions allocating on specific nodes should
484  * \brief reports the distance in the machine topology between two nodes
489  * \returns distance between two nodes
583  * \brief allocates a bit mask to represent the nodes in the system
731  * \param nodes  list of nodes to which the pages can be moved
740                          const nodeid_t *nodes,
744  * \brief migrate a domain from one set of nodes to another
747  * \param fromnodes  bitmap representing the current nodes
