Typedef Documentation

typedef Link* SD_link_t

Link datatypeA link is a network node represented as a name, a bandwidth and a latency.

A route is a list of links between two workstations.

typedef struct SD_task* SD_task_t

Task datatypeA task is some computing amount that can be executed in parallel on several hosts.

A task may depend on other tasks, which means that the task cannot start until the other tasks are done. Each task has a state indicating whether the task is scheduled, running, done, ...

Tasks

Enumerator
SD_NOT_SCHEDULED	Initial state (not valid for SD_watch and SD_unwatch).
SD_SCHEDULABLE	A task becomes SD_SCHEDULABLE as soon as its dependencies are satisfied.
SD_SCHEDULED	A task becomes SD_SCHEDULED when you call function SD_task_schedule. SD_simulate will execute it when it becomes SD_RUNNABLE.
SD_RUNNABLE	A scheduled task becomes runnable is SD_simulate as soon as its dependencies are satisfied.
SD_RUNNING	An SD_RUNNABLE task becomes SD_RUNNING when it is launched.
SD_DONE	The task is successfully finished.
SD_FAILED	A problem occurred during the execution of the task.

enum e_SD_task_kind_t

Task kinds.

SD_TASK_COMP_SEQ	sequential computation
SD_TASK_COMP_PAR_AMDAHL	parallel computation (Amdahl's law)
SD_TASK_COMM_PAR_MXN_1D_BLOCK	MxN data redistribution (1D Block distribution)
