Abstract: A system implementing a method for generating code for execution based on a SIMT model with parallel units of threads is provided. The system identifies a loop within a program that includes vector processing. The system generates instructions for a thread that include an instruction to set a predicate based on whether the thread of a parallel unit corresponds to a vector element. The system also generates instructions to perform the vector processing via scalar operations predicated on the predicate. As a result, the system generates instructions to perform the vector processing but to avoid branch divergence within the parallel unit of threads that would be needed to check whether a thread corresponds to a vector element.

Abstract: A system and method for cooling a plurality of electronics cabinets having horizontally positioned electronics assemblies. The system includes at least one blower configured to direct air horizontally across the electronics assemblies, and at least one intercooler configured to extract heat from the air flow such that the system is room neutral, meaning that the ambient temperature remains constant during operation of the system. A plurality of chassis backplanes and power supplies may also include an intercooler, wherein the intercoolers are electronically controlled such that the system is room neutral.
