NAME

       xprt_release_xprt_cong - allow other requests to use a transport

SYNOPSIS

       void xprt_release_xprt_cong(struct rpc_xprt * xprt, struct rpc_task * task);

ARGUMENTS

       xprt
	   transport with other tasks potentially waiting

       task
	   task that is releasing access to the transport

DESCRIPTION

       Note that "task" can be NULL. Another task is awoken to use the transport if the transport's congestion window allows it.

NAME

       pvm_tasks - Returns information about the tasks running on the virtual machine.

SYNOPSIS

       C    int info = pvm_tasks( int where, int *ntask, struct pvmtaskinfo **taskp )

	    struct pvmtaskinfo {
	    int ti_tid;
	    int ti_ptid;
	    int ti_host;
	    int ti_flag;
	    char *ti_a_out;
	    } taskp;

       Fortran	 call pvmftasks( where, ntask, tid, ptid, dtid, flag, aout, info )

PARAMETERS

       where   Integer specifying what tasks to return information about.  The options are:

		       0      for all the tasks on the virtual machine
		    pvmd tid  for all tasks on a given host
		      tid     for a specific task

       ntask   Integer returning the number of tasks being reported on.

       taskp   Returns	pointer  to  an array of structures which contain information about each task including its task ID, parent tid, pvmd task
	       ID, status flag, and the name of this task's executable file.  The status flag values are: waiting for a message, waiting  for  the
	       pvmd, and running.

       tid     Integer returning task ID of one task

       ptid    Integer returning parent task ID

       dtid    Integer returning pvmd task ID of host task is on.

       flag    Integer returning status of task

       aout    Character string returning the name of spawned task.  Manually started tasks return blank.

       info    Integer status code returned by the routine.  Values less than zero indicate an error.

DESCRIPTION

       The  routine  pvm_tasks	returns information about tasks presently running on the virtual machine.  The information returned is the same as
       that available from the console command ps.  The C function returns information about the entire virtual machine in one call.  The  Fortran
       function  returns  information about one task per call and cycles through all the tasks.  Thus, if where = 0, and pvmftasks is called ntask
       times, all tasks will be represented.

       Note that in Fortran the reported value of ntask and the set of tasks do not change until the function resets at  the  end  of  a  complete
       cycle.  The user can reset pvmftasks() at any time by calling it with ntask = -1.

       If pvm_tasks is successful, info will be 0.  If some error occurs then info will be < 0.

EXAMPLES

       C:
	    struct pvmtaskinfo *taskp;
	    int i, ntask;

	    info = pvm_tasks( 0, &ntask, &taskp );
	    for (i = 0; i < ntask; i++)
		      printf("t%x
", taskp[i].ti_tid);
       Fortran:
	    Do i=1, NTASK
		CALL PVMFTASKS( DTID, NTASK, TID(i), PTID(i), DTID(i),
	    &		       FLAG(i), AOUT(i), INFO )
	    EndDo

ERRORS

       The following error condition can be returned by pvm_tasks

       PvmBadParam
	      invalid value for where argument.

       PvmSysErr
	      pvmd not responding.

       PvmNoHost
	      specified host not in virtual machine.
