It is not possible to move a running process. Load balancing in a cluster occurs BEFORE the process starts - by creating the process on the least busy machine.
On a multi-cpu box, the load is shifted among processors. Once the process starts.
One other possibility is to have the same process sleeping everywhere and have it waken to handle a single request on a selected machine.

cmappmgr
cmappmgr(1m) cmappmgr(1m)
NAME
cmappmgr - launches and monitors an application process on a node
SYNOPSIS
cmappmgr -node node_name [-cmappserver_timeout number_of_seconds] -service service_name
DESCRIPTION
cmappmgr launches and monitors the specified application process on a specified node. The cmappserver(1m) daemon process must be running
on the specified node, and there must be a routable TCP/IP network between the specified node and the local host where cmappmgr(1m) is run.
cmappmgr exits when the application process exits.
Options
cmappmgr supports the following options:
-node node_name
Name of the node on which to launch the application process.
-cmappserver_timeut number_of_seconds
The number of seconds that must elapse before cmappmgr times out the connection with cmappserver on the specified node.
This is optional. The default value is 10 seconds. The maximum value that can be specified is 600 seconds, and the mini-
mum value is 1 second.
-service service_name
The full command line for the application or process to be launched. Note that -service must be the last argument speci-
fied for cmappmgr as all strings following the argument are considered as part of the command line to launch the applica-
tion process. Quotation marks ("") are not required.
RETURN VALUE
cmappmgr returns the following value upon completion:
0 Successful completion.
>= 1 One or more error conditions occurred. The value generally reflects the exit code of the process. If, for any reason, the
process fails to launch on the specified node (for example, because of an error connecting to cmappserver), cmappmgr exits with
1.
EXAMPLES
To launch an xclock application on the node v-smp1:
cmappmgr -node v-smp1 -service /usr/bin/X11/xclock -display 16:89:255:19:0.0
