Ah, so command1 command2 command3 must be executed sequentially, but the different instances can go in parallel.

Code:
for X in 1 2 3 4 5
do
        ( command1 ; command2 ; command3 ) &
done

wait

Again, be careful not to exceed the number of CPU's you have.

psradm(8)						      System Manager's Manual							 psradm(8)

NAME

       psradm, offline, online - Stops and starts processors in a multiprocessor system

SYNOPSIS

       /usr/sbin/psradm -f  [-v] [[-a] [processor_id...]]

       /usr/sbin/psradm -n  [-v] [[-a] [processor_id...]]

       /usr/sbin/online [-v] [processor_id...]

       /usr/sbin/offline [-v] [processor_id...]

OPTIONS

       The following options apply only to the psradm command: Specifies that all the processors except the master processor be put off line or on
       line.  Puts the specified processor off line.  Puts the specified processor on line.

       The following option applies to all forms of the command: Displays a message about the status of the operation performed on each processor.

DESCRIPTION

       On a multiprocessor system, the psradm command puts one or more processors off line (stops a processor) or on line (starts a processor).

       The processor_id variable specifies an integer that uniquely identifies a processor.  Use the psrinfo command to display processor  identi-
       fication numbers.

       The  offline  command puts one or more processors off line (stops a processor).	If no processors are specified, all processors that are on
       line are stopped except the master processor.

       The online command puts one or more processors on line (starts a processor).  If no processors are specified, all processors that  are  off
       line are started.

       Note that you cannot use these commands to start or stop the master processor in a multiprocessor system.

       You must be the root user to use this command.

       The /var/adm/wtmp file contains information about successful processor state transitions.

RESTRICTION

       Do not use the psradm command to disable CPUs when benchmarking performance, because the command does not provide an accurate reflection of
       the performance of a system that actually has fewer CPUs.  Accurate performance results are obtained only when you disable the CPUs at  the
       SRM console command level.

EXAMPLES

       The  following command puts processors 2 and 3 off line: # psradm -f 2 3 The following command puts all the processors on line: # psradm -n
       -a The following command puts all processors on line: # online -v
