Mechanisms for remote execution of computational tasks enable a distributed system to effectively utilize all available resources. This ability is essential to attaining the objectives of high availability, system reliability, and graceful degradation and directly contribute to flexibility, adaptability, and incremental growth. As part of a national fabric of Distributed High Throughput Computing (dHTC) services, remote execution is a cornerstone of the Open Science Grid (OSG) Compute Federation. Most of the organizations that harness the computing capacity provided by the OSG also deploy HTCondor pools on resources acquired from the OSG. The HTCondor Compute Entrypoint (CE) facilitates the remote acquisition of resources by all organizations. The HTCondor-CE is the product of a most recent translational cycle that is part of a multidecade translational process. The process is rooted in a partnership, between members of the High Energy Physics community and computer scientists, that evolved over three decades and involved testing and evaluation with active users and production infrastructures. Through several translational cycles that involved researchers from different organizations and continents, principles, ideas, frameworks and technologies were translated into a widely adopted software artifact that isresponsible for provisioning of approximately 9 million core hours per day across 170 endpoints.

原理,技术和时间:HTCondor-CE的转换历程

用于远程执行计算任务的机制使分布式系统可以有效地利用所有可用资源。此功能对于实现高可用性,系统可靠性和正常降级的目标至关重要,并且直接有助于灵活性,适应性和增量增长。作为分布式高吞吐量计算(dHTC)服务的国家架构的一部分,远程执行是开放科学网格(OSG)计算联盟的基石。大多数利用OSG提供的计算能力的组织也将HTCondor池部署在从OSG获得的资源上。HTCondor计算入口点(CE)有助于所有组织远程获取资源。HTCondor-CE是最新翻译周期的产物,它是数十年翻译过程的一部分。该过程扎根于高能物理社区成员与计算机科学家之间的合作关系,该合作关系发展了三十多年,涉及与活跃用户和生产基础架构进行测试和评估。经过来自不同组织和大洲的研究人员的多次翻译周期,原理,思想,框架和技术被翻译成广泛采用的软件工件,负责在170个端点上每天提供约900万个核心小时。它经过了三十年的发展,涉及到对活跃用户和生产基础架构进行测试和评估。经过来自不同组织和大洲的研究人员的多次翻译周期,原理,思想,框架和技术被翻译成广泛采用的软件工件,负责在170个端点上每天提供约900万个核心小时。它经过了三十年的发展,涉及到对活跃用户和生产基础架构进行测试和评估。经过来自不同组织和大洲的研究人员的多次翻译周期,原理,思想,框架和技术被翻译成广泛采用的软件工件,负责在170个端点上每天提供约900万个核心小时。
