+Note that there is no difference between running on a standalone host or in a farm. The processes are the same on each and every member of the farm. All nodes look for new Job tickets in the same folders and compete against each other getting a job assigned (depending on CPU settings, "farm host exceptions" etc.)

-==== Example Workflow Execution ====
+==== Priority flow chart and example ====
-{{:system:processes_tickets.png?200|}}
+Since the 1.1.0.0 FFAStrans release, all the jobs are processed regarding to their priority :
+\\  FFAStrans Workflow properties\Priority -> 0(Very Low)-1(Low)-2(Normal)-3(High)-4(Very High)  \\
+//**Each time a new higher priority branch (or job) is being put into queue, it will start before all lower priority queuedjobs *//
+//**Once a branch/job has been started, the priority does not matter anymore *//
+\\
+\\
+Example for 4 max active jobs on 1 host, 2 hosts with 2 max active jobs or 4 hosts with 1 max active job:

+==== Job Ticket Management ====
+{{gallery>:system:processes_tickets.png?700x350&800X800&lightbox}}
 This picture shows how the different processes work with Job Tickets.
+  - Various job starting methods create tickets (.json file) in either pending or queued folder
+  - Queued or pending tickets are being read by exe_manager
+  - exe_manager spawns a processors.a3x process for each ticket
+  - processors.a3x reads ticket, decides if the current host and CPU allows to execute the ticket and in case it executes the processor from the current ticket
+  - when the processor finished, processors.a3x parses from the workflow which processors are next to be executed and places the corresponding tickets into queued folder, the process starts over at 3
+==== The Status directory ====
+TOOD: processors.a3x checks for status pause or abort of a job split, exe_manager for ".start~%workflow_id%" to see if def_runner needs to be started
