Abstract: Computer-implemented systems and methods enable computer programming and software development using Universal Computing Element (UCE) and computing modes that use UCE's. Software, computer program, source/object/assembly code, firmware or other reconfigurable logic or signal processing instructions include at least one UCE. UCE-configured software programs in general-purpose cloud operating system function according to related or unrelated algorithms, as well as for one and/or more owners. Also such software may run on server or cloud, (private, public, or hybrid,) and/or hardware via firmware, micro-circuit, board, or equivalent functional logic.
