    3838ALMOS-MKH defines four types of threads :
    39  * one '''USER''' thread is created by a pthread_create() system call.
    40  * one '''KERNEL''' thread is created by the kernel to execute a kernel service in a cluster.
    41  * one '''RPC''' thread is activated by the kernel to execute pending RPC requests.
    42  * the  '''IDLE''' thread is executed when there is no other thread to execute on a core.
     39 * one '''USR''' thread is created by a pthread_create() system call.
     40 * one '''DEV''' thread is created by the kernel to execute all I/O operations for a given channel device.
     41 * one '''RPC''' thread is activated by the kernel to execute pending RPC requests in the local RPC fifo.
     42 * the  '''IDL''' thread is executed when there is no other thread to execute on a core.
