char * | file_prefix |
In case we are going to gather multiple traces (e.g in the case of MPI processes), we may need to prefix the name of the containers. |
struct starpu_fxt_mpi_offset | file_offset |
In case we are going to gather multiple traces (e.g in the case of MPI processes), we may need to synchronize clocks and apply an offset. |
int | file_rank |
In case we are going to gather multiple traces (e.g in the case of MPI processes), this variable stores the MPI rank of the trace file. |
struct starpu_fxt_codelet_event ** | dumped_codelets |
In case we want to dump the list of codelets to an external tool |
long | dumped_codelets_count |
In case we want to dump the list of codelets to an external tool, number of dumped codelets. |
void starpu_fxt_autostart_profiling | ( | int | autostart | ) |
Determine whether profiling should be started by starpu_init(), or only when starpu_fxt_start_profiling() is called. autostart
should be 1 to do so, or 0 to prevent it. This function has to be called before starpu_init(). See Limiting The Scope Of The Trace for more details.
void starpu_fxt_start_profiling | ( | void | ) |
Start recording the trace. The trace is by default started from starpu_init() call, but can be paused by using starpu_fxt_stop_profiling(), in which case starpu_fxt_start_profiling() should be called to resume recording events. See Limiting The Scope Of The Trace for more details.
void starpu_fxt_stop_profiling | ( | void | ) |
Stop recording the trace. The trace is by default stopped when calling starpu_shutdown(). starpu_fxt_stop_profiling() can however be used to stop it earlier. starpu_fxt_start_profiling() can then be called to start recording it again, etc. See Limiting The Scope Of The Trace for more details.
int starpu_fxt_is_enabled | ( | void | ) |
Wrapper to get value of env variable STARPU_FXT_TRACE
void starpu_fxt_trace_user_event | ( | unsigned long | code | ) |
Add an event in the execution trace if FxT is enabled. See Creating a Gantt Diagram for more details.
void starpu_fxt_trace_user_event_string | ( | const char * | s | ) |
Add a string event in the execution trace if FxT is enabled. See Creating a Gantt Diagram for more details.
