汽车仿真测试领域频频出手?天翼云为安全出行再次加码

一汽,这个拥有近30多年的整车制造技术与经验的汽车制造商,正在掀起一股智能制造的浪潮。

制造业乃国民经济的主体,是立国之本、兴国之器、强国之基。随着两化的深度融合,以云计算、大数据为代表的新兴技术,正在推动传统制造业向智能制造进行转变,推动产业和技术的新一轮创新。日前,天翼云与一汽集团正式展开合作,一汽集团依托天翼云建造的高性能计算(HPC)集群,进行汽车模拟碰撞测试,从而有效提升车辆等出行工具的安全指数。

传统制造与智能制造的“碰撞”

当前,中国汽车行业面临着转型升级的命运。近几年,AI的发展带动了自动驾驶技术的突破,但随之而来的安全问题也为其止步不前的主要因素。作为国产汽车的代表,一汽集团通过中国电信天翼云实现了技术创新和产业升级。通过天翼云专属HPC裸机服务集群,一汽的整体网络架构实现了无阻塞设计。通过集群对汽车进行模拟碰撞仿真测试,可模拟出汽车整个碰撞过程,并通过不同强度的材料在碰撞时发生的变化,对汽车安全性加以验证。

在使用HPC集群之前,汽车碰撞测试不仅需要占用大量计算平台时间,而且故障率高,严重影响使用效率,再加上建模和模型上传、计算结果回传对基地到HPC集群间的网络带宽要求高,一系列因素对汽车碰撞测试造成了阻碍。

天翼云HPC集群帮助一汽集团实现了一站式解决客户需求、提升汽车碰撞仿真平台性能、降低研发成本以及缩短产品上线周期,推动产品创新等功能,推动了一汽汽车“安全之路”的发展。

完美实现产品创新能力升级

汽车碰撞模拟测试,需要大量的高性能计算能力。一汽集团HPC集群运用了云服务的方式提供HPC计算能力,帮助一汽集团实现更低的成本、更高的性能、灵活性及可靠性。

一方面,一汽集团的服务器全部采用天翼云裸机服务,没有虚拟化损耗,保证了HPC应用对于高计算性能的要求;并且各计算节点之间使用100G IB网络,保证延时5us以内,满足大规模并行计算低延时要求。

另一方面,天翼云借助自身云平台具备的丰富资源层接入能力,还在一汽集团的专属集群中预留出了GPU服务器空间,便于其在未来与计算服务器通过10GE网络互连,满足一汽集团以后对GPU服务器的需求。

天翼云之所以能够在几家主流云服务商中脱颖而出,与其出众的产品创新能力有很大的关系。天翼云一直注重提升图形可视化、科学计算、AI训练及推理等能力,并且在生物制药和基因测序等方面展开了深度学习。

努力就会有回报,中国电信天翼云不仅是首批通过可信云GPU产品认证的云服务商之一,还是政务云服务领域唯一获得可信云认证的云服务商提供商。此外,天翼云还斩获了首届中国高性能云计算创新大赛MAXP最佳性能奖。

如何实现安全效能的完美提升?

在一汽集团之前,天翼云就已经有了HPC行业领域完美“试水”的服务经验。最典型的就是天翼云为吉利汽车提供的“最强计算大脑”。作为国内汽车品牌中的“老司机”,吉利汽车一直努力将产品的安全品质做到极致。因此,吉利汽车采用天翼云资源池和云专线建立起HPC集群,依托每秒千万亿次的计算速度和10%的计算冗余,满足了吉利汽车对于整车及零部件进行建模、仿真、测试验证方面的高要求。

吉利汽车还采用天翼云高性能CPUOpenStack标准的开放式架构,保障了HPC集群平台的兼容性和扩展性的同时,让吉利汽车研发部署的速度、成本及系统稳定性有了极大的提升。

那么究竟为何天翼云能深得吉利与一汽的心?

首先,在硬件设施方面,天翼云已经完成了“2+31”资源池布局覆盖全国,并且在各个云计算数据中心之间通过400G以上光纤电路,形成高速互联网络,保证用户可以就近接入资源池,构建500公里内20ms IT生活圈。在一汽集团服务过程中,天翼云就近部署杭州云资源池,通过独立基础架构资源池为一汽提供了强隔离的HPC集群。

同时,中国电信天翼云在全国各地拥有6万名政企客户经理和8万名专业客服技术人员,能够为客户提供从上云到用云的一站式综合服务以及属地全流程的专业保障,专业的VIP服务能力不容置疑。拥有如此出类拔萃的综合实力和专业技术能力,天翼云频繁被选也不足为奇。

当然,不仅是传统制造业,截至目前,天翼云已经在政务、医疗、教育、工业等多个领域为百万家客户提供高度专业化的云服务,在助力企业数字化转型中发挥了重要作用。

事实上,企业的数字化转型和云计算的发展相辅相成。前者是推动后者发展的重要原因,而上云是企业实现数字化转型的第一步。天翼云身为云服务的“国家队”,未来必将在推动企业数字化转型以及数字中国建设过程中做出更大的贡献。
