typedef void(* orte_ess_base_module_abort_fn_t)(int status, bool report) __opal_attribute_noreturn_funcptr__ |
Abort the current application.
Aborts currently running application, NOTE: We do NOT call the regular C-library "abort" function, even though that would have alerted us to the fact that this is an abnormal termination, because it would automatically cause a core file to be generated. The "report" flag indicates if the function should create an appropriate file to alert the local orted that termination was abnormal.
typedef int(* orte_ess_base_module_ft_event_fn_t)(int state) |
Handle fault tolerance updates.
[in] | state | Fault tolerance state update |
ORTE_SUCCESS | The operation completed successfully |
ORTE_ERROR | An unspecifed error occurred |
typedef opal_paffinity_locality_t(* orte_ess_base_module_get_proc_locality_fn_t)(orte_process_name_t *proc) |
Get the locality flag of the specified process.
MPI procs need to know whether a proc shares a common socket, board, node, computing unit, or cluster. This function provides a means for an MPI proc to query the locality of another proc.
typedef orte_vpid_t(* orte_ess_base_module_proc_get_daemon_fn_t)(orte_process_name_t *proc) |
Get the vpid of the daemon who hosts the specified proc.
In order to route messages to the correct place, the RML and routed modules need to know the vpid of the daemon that hosts the intended recipient. This API accesses the pidmap/nidmap to retrieve that info
typedef int(* orte_ess_base_module_proc_get_epoch_fn_t)(orte_process_name_t *proc) |
Update the epoch.
The epochs of the processes are stored in the process_name struct, but this will get the most up to date version stored within the orte_proc_t struct. Obviously the epoch of the proc that is passed in will be ignored.
typedef char*(* orte_ess_base_module_proc_get_hostname_fn_t)(orte_process_name_t *proc) |
Get the hostname where a proc resides.
MPI procs need to know the hostname where a specified proc resides. Different environments provide that info in different ways - e.g., they may provide a callable utility to return the answer, or download a map of information into each process. This API provides a means for each environment to do the "right thing".
NOTE: To avoid memory waste, this function returns a pointer to a static storage. IT MUST NOT BE FREED!
typedef int(* orte_ess_base_module_update_nidmap_fn_t)(opal_byte_object_t *bo) |
Update a nidmap.
When a job is dynamically launched via comm_spawn, the pre-existing daemons need to update their knowledge of the node map that contains info on what daemon resides on which nodes
typedef int(* orte_ess_base_module_update_pidmap_fn_t)(opal_byte_object_t *bo) |
Update the pidmap.
When a job is dynamically launched via comm_spawn, the pre-existing daemons need to update their knowledge of the process map within the job so they can properly do things like route messages. This API allows daemons - and anyone else who wants to - to add a pidmap for a new job
