一句话：指出现有执行迁移依赖同构 ISA，提出异构 ISA 数据中心如何应用执行迁移的核心问题。
能效是现代数据中心运行的重要设计考量，数据中心操作系统依赖执行迁移在同构 ISA 机器池中提升能效。当前执行迁移之所以可行，是因为数据中心主要由同构 ISA 机器组成。然而市场趋势显示 ARM 和 PowerPC 等替代 ISA 正进入数据中心，这意味着现有执行迁移技术不再适用。论文由此提出核心问题：未来异构 ISA 数据中心应如何应用执行迁移？摘要仅提出该开放问题，未给出具体机制、系统实现或评估结果；标题表明其目标是在异构 ISA 数据中心中突破边界。
Energy efficiency is one of the most important design considerations in running modern datacenters. Datacenter operating systems rely on software techniques such as execution migration to achieve energy efficiency across pools of machines. Execution migration is possible in datacenters today because they consist mainly of homogeneous-ISA machines. However, recent market trends indicate that alternate ISAs such as ARM and PowerPC are pushing into the datacenter, meaning current execution migration techniques are no longer applicable. How can execution migration be applied in future heterogeneous-ISA datacenters?
