01640 M00S01605.smfex +++|* FOR RUNJOBS ITSELF TO USE REENTRANT ENTRY AND EXIT EVEN
01641 M00S01606.smfex +++|* THOUGH ITS SUBROUTINES ARE THEMSELVES REENTRANT.

01643 M00S01608.smfex +++|* NOTE THAT THERE IS NO ARCHITECTURAL PROTECTION AGAINST

01647 M00S01612.smfex +++|* SENSITIVE AND REASONABLE IN RESOURCE CONSUMPTION SINCE THIS
01648 M00S01613.smfex +++|* SUBSYSTEM EXECUTES AT A VERY HIGH PRIORITY.
01649 M00S01614.smfex +++|*
01650 M00S01615.smfex +++|* RUNJOBS PERFORMS TWO PRELIMINARY PHASES BEFORE INITIATING

01654 M00S01619.smfex +++|* PHASE CHECKS FOR SHUTDOWN CONDITIONS.
01655 M00S01620.smfex +++|*
01656 M00S01621.smfex +++|* THE PRINCIPAL FUNCTION OF RUNJOBS IS TO ADVANCE THE STATUS
01657 M00S01622.smfex +++|* OF EACH AVAILABLE TASK. WHILE THE SUBSYSTEM IS COMPILED
01658 M00S01623.smfex +++|* WITH A LARGE NUMBER OF TASKS IN EXISTENCE, THE NUMBER OF

01662 M00S01627.smfex +++|* EACH TASK CAN HAVE ANY OF THE FOLLOWING STATUSES --
01663 M00S01628.smfex +++|*
01664 M00S01629.smfex +++|* 1. IT MAY BE EMPTY. AN EMPTY TASK WILL BE ASSIGNED TO A
01665 M00S01630.smfex +++|* USER IF THERE ARE USERS IN THE SCHEDULING (SWAPIN) QUEUE
01666 M00S01631.smfex +++|* AND NO SHUTDOWN CONDITION EXISTS. IN ASSIGNING A USER TO A
01667 M00S01632.smfex +++|* PREVIOUSLY EMPTY TASK, THE TASK STATUS IS CHANGED TO
01668 M00S01633.smfex +++|* "START" OR "SWAPIN" BASED ON THE USER'S PROGRESS.
01669 M00S01634.smfex +++|*
01670 M00S01635.smfex +++|* 2. IT MAY BE DELAYING. A DELAYING TASK MISSES THE CPU FOR
01671 M00S01636.smfex +++|* PRECISELY ONE SMFEX CPU RECALL CYCLE, AND TYPICALLY IS
01672 M00S01637.smfex +++|* WASTING REAL TIME WHILE POLLING ON COMPLETION OF AN I/O
01673 M00S01638.smfex +++|* FUNCTION. IN VIEW OF THE BRUTE FORCE REQUIRED TO RESTART A
01674 M00S01639.smfex +++|* DELAYED TASK, THIS STYLE OF WAITING FOR I/O IS NOT USED
01675 M00S01640.smfex +++|* OFTEN WITHIN THE EDITING CODE, BUT IT IS FULLY SUPPORTED BY
01676 M00S01641.smfex +++|* THIS EXECUTIVE. RUNJOBS RESTARTS A DELAYED TASK AS SOON AS
01677 M00S01642.smfex +++|* IT IS DISCOVERED, BY CHANGING THE TASK STATUS TO "RUN".
01678 M00S01643.smfex +++|*
01679 M00S01644.smfex +++|* 3. A TASK MAY BE IN AUTO RECALL. THIS TASK WISHES TO MISS
01680 M00S01645.smfex +++|* THE CPU UNTIL SMFEX DETECTS THAT THE SPECIFIED COMPLETION
01681 M00S01646.smfex +++|* BIT HAS BEEN TOGGLED BY ANYBODY. THIS IS THE METHOD
01682 M00S01647.smfex +++|* GENERALLY USED WITHIN THE EDITOR TO WAIT FOR I/O, SINCE IT
01683 M00S01648.smfex +++|* AVOIDS WASTING CPU TIME TO START UP A DELAYED TASK WHICH IS
01684 M00S01649.smfex +++|* LIKELY TO DROP RIGHT BACK INTO DELAY. ONCE SMFEX VERIFIES
01685 M00S01650.smfex +++|* THAT THE DESIRED EVENT IS COMPLETE, IT RESTARTS A RECALLED
01686 M00S01651.smfex +++|* TASK BY CHANGING THE TASK STATUS TO "RUN".
01687 M00S01652.smfex +++|*
01688 M00S01653.smfex +++|* 4. A TASK MAY BE IN "START" STATUS. THIS TASK IS READY
01689 M00S01654.smfex +++|* FOR THE CPU, FOR A USER WHO HAS NOT YET EXECUTED ANY
01690 M00S01655.smfex +++|* MULTI-USER EDITING CODE. THE TASK WILL GET THE CPU AT THE
01691 M00S01656.smfex +++|* EDITOR'S MAIN ENTRY POINT. NO SWAP PAGE EXISTS YET, AND
01692 M00S01657.smfex +++|* DISPATCHING DATA IS IN MODEL FORMAT.
01693 M00S01658.smfex +++|*
01694 M00S01659.smfex +++|* 5. A TASK MAY BE IN "SWAPIN" STATUS. THIS TASK HAS
01695 M00S01660.smfex +++|* PREVIOUSLY EXECUTED AND SWAPPED OUT. THE TASK THEREFORE
01696 M00S01661.smfex +++|* WANTS THE CPU AT THE ENTRY POINT OF THE SWAPPING CODE.
01697 M00S01662.smfex +++|* SINCE THE SWAPOUT AND SWAPIN CODE ARE ONE AND THE SAME,
01698 M00S01663.smfex +++|* TASK CPU DISPATCHING IS EFFECTED BY RETURNING TO THE SWAP
01699 M00S01664.smfex +++|* CODE WHERE CONTROL WAS PREVIOUSLY SURRENDERED. THAT SWAP
01700 M00S01665.smfex +++|* CODE WILL READ IN THE SWAP CODE AND ALTER THE MEMORY IMAGE
01701 M00S01666.smfex +++|* FOR THE TASK ON THE FLY, THEN RETURN OUT THE THE EDITING
01702 M00S01667.smfex +++|* CODE WHICH HAD CAUSED THE PREVIOUS SWAPOUT.
01703 M00S01668.smfex +++|*
01704 M00S01669.smfex +++|* 6. A TASK MAY BE IN "RUN" STATUS. THIS TASK HAS BEEN
01705 M00S01670.smfex +++|* SWAPPED IN FOR SOME TIME, AND IS PRESENTLY COMPLETING A
01706 M00S01671.smfex +++|* DELAY OR RECALL. SINCE THE MEMORY IMAGE FOR THE TASK IS

01709 M00S01674.smfex +++|* THE EDITING CODE WHERE THE TASK HAD PREVIOUSLY PAUSED.
01710 M00S01675.smfex +++|*
01711 M00S01676.smfex +++|* EACH TIME A TASK GETS THE CPU, IT CAN FINISH ITS TIME SLICE
01712 M00S01677.smfex +++|* IT THREE WAYS -- (1) THE ENTIRE EDIT SESSION MAY END, IN
01713 M00S01678.smfex +++|* WHICH CASE THE TASK EXITS VIA LABEL "AFTEREDIT" FOR CLEANUP
01714 M00S01679.smfex +++|* PROCESSING, OR (2) THE TASK MAY COMPLETE A TRANSACTION,

01721 M00S01686.smfex +++|*
01722 M00S01687.smfex +++|* IN SUMMARY, THERE ARE THREE WAYS FOR A TASK TO BE ASSIGNED
01723 M00S01688.smfex +++|* THE CPU (START OF SESSION, START OF TRANSACTION, OR RESTART
01724 M00S01689.smfex +++|* AFTER DELAY) AND THREE WAYS FOR A TASK TO FORFEIT THE CPU
