One-to-one Task to Node mapping

How can we realize the following job scheduling problem:
Maybe with own PowerShell scripting.We have jobs of several application and every job has several thousand of tasks.
The task itself runs very short (10 sec).
Now we have the limitation that every task of an application can run only once on a node.
The mapping is also a 1-to-1 task to node of every applicationJob1 of App1
|-------- Task1 --> Node 1
|-------- Task2 --> Node 2
+-------- Task3 --> Node 3Job<n> of App2
|-------- Task1 --> Node 3
|-------- Task2 --> Node 2
|------- Task3 --> Node 1
+------- Task4 --> Wait until a node is free

Hi,
Please take a look at this http://technet.microsoft.com/en-us/library/cc972879(v=ws.10).aspx
You need to specify "NumNodes 1" for each task in your job.

Hello Michael,
thank you for your answer. We had tested what you are suggest before we made this entry in the forum. The problem is, when we use the "NumNodes 1" parameter, only one task from one job can run on the node.We want to have that only one task from each job can run simulatious on one node.
For example if we have 4 jobs with 10 tasks each on every node should run 1 task from job 1, 1 task from job 2, ...
Best regards

Hi Steffen,
I don't know if I quite get that, did you try to set the scheduler mode to 'balanced'?

How about /nodegroup: /numcores: together
Task1 (App1,App2,App3 ...) job submit /nodegroup:Node1 /numcores:1-1
Task2 (App1,App2,App3 ...) job submit /nodegroup:Node2 /numcores:1-1
etc...
