# executorgetconcurrencylevel

Purpose
Fetch the currently configured concurrency level of the Xpress Executor 3 component.
Synopsis
`function executorgetconcurrencylevel(exec:Executor):integer`
Argument

exec | The Executor to query

Return value
The number of executions that can be performed concurrently on a single Xpress Executor gear
Example

    declarations
      concurrencylevel: integer
    end-declarations
    concurrencylevel := executorgetconcurrencylevel( myexecutor )
    if myexecutor.status<>EXECUTOR_OK then
      writeln("Error returned by Executor: ",myexecutor.lasterror)
      exit(1)
    end-if

Further information
1. After calling, check the value of exec.status for any errors.
2. "Concurrency Level" is the number of executions that can be performed concurrently on a single gear; if the Xpress Executor component is scaled over multiple gears then the total number of concurrent executions will be concurrencylevel*numgears
3. If you start an execution when the maximum number of executions are concurrently executing, new executions are queued and will start when other executions complete.
4. This will always be 1 if the Executor is configured in local mode.
