Grid compute node

Hi All,
Can you please let me know why we would pass 2 values to APT_Grid_computenodes
From what I read about the Apt variable I was thinking it should have a single value passed to it. But in the current environment for a new customer I see values passed like the below:
Apt_grid_computenodes=2,2 or 12,3 etc

It should be just a single value.

Hi
Thanks for the reply. I was under the same assumption reading the IBM manuals but as I mentioned two numbers are passed to this variable .

Unless the toolkit has been changed; I don't see why two values are needed. You can take a look the log from the Director; it has more detailed nodes assignments info. It should give you a clue what's going on with the second value. My guess is that the second value dosen't do anything and/or doesn't need at all.

12,3 ---> 12 nodes but restrict to 3 servers.
Smaple config for 6,3 is below.

correction to the above post...
12,3 ---> 12 tasks but restrict to run on only 3 nodes.

Best when you post stuff like this to
remove any client-specific information. And don't post a correction, go back and edit the original post.
