c tminfo.h -- worker and tile (tower) state arrays
c             used in tm.f routines
c
c     // tile information array
c
      integer tileInfo(4,MAXTILES), HOME,STATE,TX,TY
      parameter (HOME=1, STATE=2, TX=3,TY=4)
c
c     // possible states for a tile.  Actually, if >0 means ASSIGNED
c        to -that- numbered CM.

      integer DONE, READY
      parameter (DONE=-2, READY=-1 )
c
c DONE: a tile has been created/updated as part of the current update cycle
c READY: a tile is eligable for assignment of creation/update for current cycle
c >0     Asigned to a cm
c ====

c ==== worker status - we share the ASSIGNED interpretation with tile status,
c      that is: >0 ASSIGNED means assigned -that- tile number
c      -that- tile number.
c
      integer nextWorkerState(MAXCM), workerState(MAXCM)
      integer FREE, ASLEEP
      parameter (FREE=-2, ASLEEP=-1)
c
c FREE: worker is idle, ready for task assignment
c ASLEEP: worker is online but should not be assigned work
c >0    Assigned work in progress
