ECLIPSE licensing model

[FET]

Folks:

I have a silly question relating to the Schlumberger licensing model for ECLIPSE licenses...

Can anyone confirm or give an idea if for example the ECLIPSE core E100 licenses and other modules are:

- licensed per server / workstation (so one license is required per computer)
- licensed per CPU socket (so one license is required to run simulations on a 4-core processor)
- licensed per CPU core (so that 16 licenses would be required to run simulations on all processors in a dual-socket 8 core server).
- licensed some other way than per-node or per-CPU ?

I would like to plan some environments and can't find the answer via google... Some places give the impression that the license is "per node" meaning I would use one ECLIPSE license per server that runs all the simulations (one per core as many cores as the box has) and other places seem to give the impression that ECLIPSE is licensed per core (meaning that for 4 servers with 8 cores each, I would need 32 ECLIPSE licenses per environment if I wanted to run 32 simultaneous simulations).

And how does parallel versus serial work? If I have a single E100 black-oil core license, can I use an 8-way parallel license to run the same simulation across 8 cores (or 8 servers) to run the job faster? If so, would the multiplier be per-core or per server? (because that means I will probably need a lot more parallel licenses). Do you typically buy one ECLIPSE license per model and use parallel to run big jobs to save $ on ECLIPSE licenses?

I think that when LSF submits a simulation job to a particular server, a license is checked out to that server to run the job. (What I am not clear on is do I need 8 licenses to run 8 simulations on a single server?)

Thank you in advance,
FT
