    - #### IgniteStripedThreadPoolExecutor

          public IgniteStripedThreadPoolExecutor(int concurrentLvl,
                                                 String igniteInstanceName,
                                                 String threadNamePrefix,
                                                 Thread.UncaughtExceptionHandler eHnd,
                                                 boolean allowCoreThreadTimeOut,
                                                 long keepAliveTime)

      Create striped thread pool.
      Parameters:
        `concurrentLvl` - Concurrency level.
        `igniteInstanceName` - Node name.
        `threadNamePrefix` - Thread name prefix.
        `allowCoreThreadTimeOut` - Sets the policy governing whether core threads may time out and terminate if no tasks arrive within the keep-alive time.
        `keepAliveTime` - When the number of threads is greater than the core, this is the maximum time that excess idle threads will wait for new tasks before terminating.
        `eHnd` - Uncaught exception handler.
