 '''What is the difference between a Limulus and 6/8/12/16 core workstation?'''
-In terms of core count, there is no difference. In terms of performance there can be a big difference. A multi-core SMP system (such as a dual socket workstation or server motherboard) can provide many cores, but depending on the workload, you may not be able to get effective use from all the cores due to memory contention. In a cluster design, like Limulus, each node has exclusive access to the local memory. In addition, unused nodes can be powered off.

In a cluster design, like Limulus, each node has one processor socket with exclusive access to the local memory. In addition, unused nodes can be powered off.
 
 '''What is the intended market?'''

 Yes. There is a front panel that provides video, USB, and a power switch for each motherboard.
 
-Why don't you pack a bunch of 12-core processors into the case?'''
+'''Why don't you pack a bunch of 12-core processors into the case?'''
 Because Limulus is designed with a heat/power/performance envelope. An HPC server can pack in cores because in a data center, there is dedicated power, cooling, and a tolerance for fan noise. Have you ever run an HPC server (or two) next to your desk?'''
