PetscLogEventRegister() is 666 intended for logging user events to supplement this PETSc 667 information. 668 669 PETSc can gather data for use with the utilities Jumpshot 670 (part of the MPICH distribution). If PETSc has been compiled 671 with flag -DPETSC_HAVE_MPE (MPE is an additional utility within 672 MPICH), the user can employ another command line option, -log_mpe, 673 to create a logfile, "mpe.log", which can be visualized 674 Jumpshot. 675 676 The classid is associated with each event so that classes of events 677 can be disabled simultaneously, such as all matrix events. The user 678 can either use an existing classid, such as MAT_CLASSID, or create 679 their own as shown in the example. 680 681 If an existing event with the same name exists, its event handle is 682 returned instead of creating a new event. 683 684 Level: intermediate 685 686 .keywords: log, event, register 687 .seealso: PetscLogEventBegin(), PetscLogEventEnd(), PetscLogFlops(), 688 PetscLogEventActivate(), PetscLogEventDeactivate(), PetscClassIdRegister() 689 @*/ 690 PetscErrorCode PetscLogEventRegister(const char name[],PetscClassId classid,PetscLogEvent *event) 691 { 692 PetscStageLog stageLog;
