I have a 128core HP server running Ubuntu with blender 2.73a. When I try to render somthing, it only workes one section at a time and runs very slow compared to my desktop box which is much smaller.
It looks/acts like it’s running on a single thread (core).
Sugestions?

if you see only one section at a time it might be because you have set to render on your GPU compute device. make sure you set the rendering device to be CPU
