We have some new 8 core machines on our CCS, is there a way to tell CCS to only use 4 of 8 for these new machines?

Hi,
We have nice support for core placement in the beta of our next product. You could specify 2 cores per socket kind of job placement.
For more information on the beta please see: http://connect.microsoft.com or http://www.microsoft.com/hpc.

Are you using MPI? in that case you can tell MPI to use only some of the CPU's. For example,
job submit ..... mpiexec -hosts %%CCP_NODES: 8= 2%%
(note the space before 8 and before 2. the double %% is to escape the % and pass it for execution on the node)
this command will replace 8 with 2 and will end up running 2 processes on each node (rather than 8)
hope this helps,
