Multidimensional array with start-job

Question

Hi! I'm trying to improve a script that will read in a CSV file to an array, divide it up to 4 chunks. So I will have 4 arrays and inside each array I have properties for computername, ip addresses and so forth. ($arrComputers[0][56].ComputerName)
So what I want to do is:
# Send 1 chunk array at a time to a Start-Job. 1 chunk consits of 100 computers.
# Read each object,  $arrComputers[index][row].Status ,
# If Status says "OK" don't continue to check, Else continue to fetch info and write back to
$arrComputers[index][row].<property>
So for I've only gotten to 
$Script={
Param($comp)
<Do Check, Read and Write for each computer here>
for($i=0;$i -lt 4;$i++)
$compCollection[$i] | Start-Job -ScriptBlock $Script -ArgumentList ($compCollection[$i]
I hope I have been clear what I'm trying to do. This is my first time trying it, so wouldn't surprise me if you guys got a better idea how to achieve what I want or what I've done wrong. I'm all ears and also to pointers to guides and such where I can read
up more about advanced powershelling.

$computerlist | 
     ForEach-Object{
         Start-Job -Script $script
-ArgumentList $_
but
$script={Param($computer)
if($computer.Status -eq "OK"){
#Do Nothing
else
#Do Something
$computer.Status = #Assign new value
#write back the same chunk it derived from.
for($i=0;$i -lt 4;i++){
$computerlist[$i] |
ForEach-Object{
Start-Job -Script $script -ArgumentList $_
