There are multicore safe locks for file access and heap allocations, however, so TempleOS is symmetrical in some sense. See $LK,"::/Demo/MultiCore/LoadTest.HC"$.
Only tasks on $FG,2$core0$FG$ can have windows, but other cores can help render them.
Only tasks on $FG,2$Core0$FG$ can have windows, but other cores can help render them.
Each core has an executive $FG,2$seth task$FG$ which is the father of all tasks on that core. Adam is the seth task on core 0.
Each core has an executive $LK,"Seth Task",A="FF:::/Doc/Glossary.DD,Seth Tasks"$ which is the father of all tasks on that core. $LK,"Adam",A="FF:::/Doc/Glossary.DD,Adam Task"$ is the $LK,"Seth Task",A="FF:::/Doc/Glossary.DD,Seth Tasks"$ on $FG,2$Core0$FG$.
You give a job to a seth task with $LK,"JobQue",A="MN:JobQue"$() and get the res with $LK,"JobResGet",A="MN:JobResGet"$(). You spawn a task on another core with $LK,"Spawn",A="MN:Spawn"$().
You give a job to a $LK,"Seth Task",A="FF:::/Doc/Glossary.DD,Seth Tasks"$ with $LK,"JobQue",A="MN:JobQue"$() and get the res with $LK,"JobResGet",A="MN:JobResGet"$(). You spawn a task on another core with $LK,"Spawn",A="MN:Spawn"$().
Note: You must use the $FG,2$LOCK$FG$ asm prefix when changing shared structures in a multicore environment. The $LK,"LBts",A="MN:LBts"$(), $LK,"LBtr",A="MN:LBtr"$() and $LK,"LBtc",A="MN:LBtc"$() insts have $FG,2$LOCK$FG$ prefixes. The compiler has a $FG,2$lock{}$FG$ feature but it doesn't work well.
