With GNU xargs, you can use the -P option to run jobs in parallel. So
would run your program with each line of input provided as the arguments to myprogram, and 4 jobs would be started at a time.
To distribute among several Linux nodes, you can build a cluster, as Neo suggested.
OR you can use ssh/rsh to distribute run the jobs on the other hosts. First, make a file containing the hostnames of your cluster. If a host has 2 CPUs, have the hostname entry twice. If it has 4 cores, have 4 entries of that hostname.
From here you can go in different directions, but ultimately, you run one rsh/ssh process her line in this hosts file.

bos_exec
BOS_EXEC(8) AFS Command Reference BOS_EXEC(8)NAME
bos_exec - Executes a command on a remote server machine
SYNOPSIS
bos exec -server <machine name> -cmd <command to execute>
[-cell <cell name>] [-noauth] [-localauth] [-help]
bos e -s <machine name> -cm <command to execute>
[-ce <cell name>] [-n] [-l] [-h]
DESCRIPTION
The bos exec command executes the indicated command on the file server machine named by the -server argument. Its intended use is to reboot
the machine, using the /sbin/reboot command or equivalent.
OPTIONS -server <machine name>
Indicates the server machine on which to execute the command. Identify the machine by IP address or its host name (either fully-
qualified or abbreviated unambiguously). For details, see bos(8).
-cmd <command to execute>
Specifies the complete local disk pathname of the command to execute (for example, /sbin/reboot). Surround this argument with double
quotes ("") if the command contains one or more spaces.
-cell <cell name>
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see bos(8).
-noauth
Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag with the -localauth flag. For more details, see
bos(8).
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The bos command interpreter presents the ticket
to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see
bos(8).
-help
Prints the online help for this command. All other valid options are ignored.
EXAMPLES
The following command reboots the machine "fs2.abc.com". The issuer has previously issued the bos shutdown command to shutdown all
processes cleanly.
% bos exec -server fs2.abc.com -cmd /sbin/shutdown -r now
PRIVILEGE REQUIRED
The issuer must be listed in the /etc/openafs/server/UserList file on the machine named by the -server argument, or must be logged onto a
server machine as the local superuser "root" if the -localauth flag is included.
The bos exec command is not available on servers running in restricted mode.
