Data Comprising functions

1. A data center, comprising:

at least three computing units, each computing unit comprising:

processing resources for performing a computing function;

memory resources for storing data;

at least two wireless communication elements, each for communicating with at least one other computing unit using wireless communication, and each forming a directionally-focused beam; and

switching resources for coupling together the processing resources, memory resources, and said at least two wireless communication elements.

2. The data center of claim 1, wherein the wireless communication comprises high frequency RF wireless communication.

3. The data center of claim 1, wherein the wireless communication comprises optical wireless communication.

4. The data center of claim 1, wherein said at least three computing units comprise at least two groups of computing units, and wherein each computing unit includes at least one intra-group wireless communication element for communicating with at least one other computing unit in a local group, and at least one inter-group communication element for communicating with at least one other computing unit in at least one neighboring group.

5. The data center of claim 1, wherein said at least three computing units comprises a group of computing units that form a columnar structure, the columnar structure having an inner free-space region for accommodating intra-group communication among computing units within the group.
