“如果没有可以使用Red Hat Enterprise Linux跨域安全性的工作负载经理,我们被迫在每个安全级别安装我们的调度程序版本,并由白板管理HPC资源,”Swartz说。“每个安全级别被分配给特定的硬件资源集,因此如果安全级别在给定时间未运行,则浪费这些资源,因为它们无法在不同的安全级别的其他用户共享。”
解决方案:Altair的PBS Professional对Red Hat Enterprise Linux的跨域安全支持
洛克希德马丁evaluated all proven HPC resource management vendors and closely investigated the ability of each vendor to meet queuing and prioritization requirements, as well as the company’s willingness to work with Lockheed Martin to make the code modifications required to bring the scheduler into compatibility with Red Hat crossdomain configurations.
“我们选择Altair感谢PBS Professional丰富的排队,管理和报告能力,并公司愿意与我们创新,”Swartz说。“带有Red Hat的PBS专业实施在设置队列和工作优先级方面提供了广泛的灵活性,它提供了自动化会计信息和我们需要的许多其他功能,以确保每个用户在适当的时间内完成他的工作,并具有适当的优先级。”
”Red Hat Enterprise Linux features tight integration with SELinux, which enables the platform’s native configurations to offer role-based access control (RBAC), data labeling, and continuous monitoring of security controls,” explained Shawn Wells, Director of Innovation Programs, Red Hat Public Sector. “Through PBS Professional, Altair abstracts these technical complexities to provide a consumable interface for cross-domain supercomputing, supporting multi-level security and unifying underlying security controls with workload management.” Lockheed Martin worked closely with Altair to ensure the software met the highest levels of security requirements to work correctly in a Red Hat Enterprise Linux cross-domain environment. Lockheed Martin originally installed PBS Professional on two SGI UV100 systems and quickly added three additional systems. They then installed five Cray® CS™ distributed-memory clusters in their new datacenter with a total of 388 sockets, representing the first use of MLS on distributed-memory cluster systems.
结果:节省成本和提高全系统效率
由于PBS专业安装支持跨域安全性,洛克希德马丁现在可以实时地实时管理HPC资源,以上超过20个不同的安全级别和隔间,确保完整的系统利用率。
此外,通过提供跨域超级计算平台,Altair-Red Hat解决方案使能洛克希德马丁能够大大减少HPC采购成本,以支持大型美国政府计划。洛克希德Martin将资源维护到两个超级计算机,而不是将单独的HPC系统维护,而是在提前节省,减少了数据中心占地面积和功耗,以及简化的IT架构中导致数千万美元。
