    • An execution trace of building blocks of computer code includes a head building block at which the execution trace starts, and a tail building block at which the execution trace ends. The building blocks are executable in a sequence from the head building block to the tail building block. The execution trace is truncated at a particular building block of the execution trace, which becomes the tail building block. The particular building block can correspond to a head building block of an additional execution trace, and/or to a loop header building block of a loop within the execution trace and at which the loop is entered. The execution trace is a compilation unit on which basis a trace-based compiler computer program generates an executable version of the code at least by compiling these units.
    • 计算机代码的构建块的执行跟踪包括执行跟踪开始的头构建块和执行跟踪结束的尾部构建块。 构建块可以从头部构造块到尾部构造块的顺序执行。 执行跟踪在执行跟踪的特定构建块处被截断,这将成为尾部构建块。 特定构建块可以对应于附加执行跟踪的头部构造块,和/或对应于执行跟踪内的循环的循环头部构造块,并且进入循环。 执行跟踪是一个编译单元,在该基础上,基于跟踪的编译器计算机程序至少通过编译这些单元来生成代码的可执行版本。

    • A method, computer program product, and information handling system for generating loop code to execute on Single-Instruction Multiple-Datapath (SIMD) architectures, where the loop contains multiple non-stride-one memory accesses that operate over a contiguous stream of memory is disclosed. A preferred embodiment identifies groups of isomorphic statements within a loop body where the isomorphic statements operate over a contiguous stream of memory over the iteration of the loop. Those identified statements are then converted into virtual-length vector operations. Next, the hardware's available vector length is used to determine a number of virtual-length vectors to aggregate into a single vector operation for each iteration of the loop. Finally, the aggregated, vectorized loop code is converted into SIMD operations.

    • An admission method, an admission apparatus, and a communication system are disclosed. The admission method includes: obtaining timeslot utilization efficiency R1 of a first User Equipment (UE) that needs to access a system and timeslot utilization efficiency R2 of a second UE that has accessed the system; judging whether the difference between R1 and R2 is greater than a first decision threshold; and allowing the first UE to access the system if determining that the difference between R1 and R2 is greater than the first decision threshold. The admission method provided herein is applicable to a communication system, and can improve the timeslot utilization efficiency and the throughput of the system.
