2.16: What is deadbeef?

"When running the debugger (dbx), you may have wondered what the 'deadbeef' is you occasionally see in registers. Do note, that 0xdeadbeef is a hexadecimal number that also happens to be some kind of word (the RS/6000 was built in Texas!), and this hexadecimal number is simply put into unused registers at some time, probably during program startup."

So it doesn't appear to be a problem. No sites came up saying it's a virus or the result of a hacker. And when you think about it, all the letters are hexadecimal ... A-F. Smilie

Need Script to Use CPUs on a HPUX server to simulate Workload Manager on HPUX.

I am running HPUX and using WLM (workload manager). I want to write a script to fork CPUs to basically take CPUs from other servers to show that the communication is working and CPU licensing is working. Basically, I want to build a script that will use up CPU on a server. Any ideas?

ipcrm

IPCRM(1)						    BSD General Commands Manual 						  IPCRM(1)

NAME

     ipcrm -- remove the specified message queues, semaphore sets, and shared memory segments

SYNOPSIS

     ipcrm [-M shmkey] [-m shmid] [-Q msgkey] [-q msqid] [-S semkey] [-s semid] ...

DESCRIPTION

     ipcrm removes the specified message queues, semaphores, and shared memory segments.  These System V IPC objects can be specified by their
     creation ID or any associated key.

     The following options are used to specify which IPC objects will be removed.  Any number and combination of these options can be used:

     -M shmkey
	     Mark the shared memory segment associated with key shmkey for removal.  This marked segment will be destroyed after the last detach.

     -m shmid
	     Mark the shared memory segment associated with ID shmid for removal.  This marked segment will be destroyed after the last detach.

     -Q msgkey
	     Remove the message queue associated with key msgkey from the system.

     -q msqid
	     Remove the message queue associated with the ID msqid from the system.

     -S semkey
	     Remove the semaphore set associated with key semkey from the system.

     -s semid
	     Removes the semaphore set associated with ID semid from the system.

     If the id or key argument is ``all'' then all entries of the appropriate type are removed.

     The identifiers and keys associated with these System V IPC objects can be determined by using ipcs(1).
