IBM推出首款采用Power9处理器的服务器AC922 Power Systems

  日前,IBM公司推出了第一款使用新型Power9处理器的AC922 Power Systems,这款处理器专为计算繁重的人工智能工作负载而设计。
  
  IBM公司声称,作为第一个嵌入PCIe 4.0,Nvidia NVLink和Open CAPI的系统,AC922系统使数据移动速度比基于PCIe3.0的x86系统快9.5倍。
  
  IBM公司表示,该系统采用流行的人工智能框架(如Chainer,TensorFlow和Caffe)和Kinetica等加速数据库。
  
  该公司声称采用这款之后,Chainer的性能提高了3.7倍,Caffeoverx86的性能提高了3.8倍。
  
  IBM公司认知系统高级副总裁Bob Picciano说:“我们已经为人工智能和认知工作负载建立了一个改变游戏规则的巨人。
  
  IBM Power9 Systems除了配置世界上最强大的超级计算机之外,还旨在帮助世界各地的企业提供前所未有的洞察力,推动科学发现,促进各行业的转型业务成果。”
  
  谷歌云平台副总裁Bart Sano补充说:“我们对于IBM公司在开发最新的服务器技术方面取得的进展感到兴奋。Power9 Open CAPI总线和大容量存储器功能为谷歌的数据中心的创新提供了更多机会。”
  
  Power9系统也将用于美国能源部的“首脑会议”和“塞拉利昂”超级计算机中,作为CORAL项目的一部分,有望在明年成为世界上最强大的超级计算机。
  
  Stefanie Chiras测试AC922 Power Systems服务器
  
  IBM公司认知系统的PowerSystems副总裁Stefanie Chiras表示,“我们致力于交付更好的产品,并正在按计划交付橡树岭国家实验室,这真是棒极了。”
  
  Chiras公司补充说,IBM公司正在考虑为高性能计算系统开发创新产品,并将其转化为面向更广泛市场的产品:“这是为了使CORAL的技术创新成为可能,并使企业能够轻松地使用这些人工智能工作负载。我认为这个高性能计算领域的重点和技术可以很好地转化为人工智能领域。”
  
  IBM公司在2014年推出的Power8就彻底改变了策略,当时它的设计可以从Open Power Foundation获得许可。
  
  Chiras说:“随着Power8的推出,我们宣布将改变业务,以满足我们希望推向市场的价值主张。就像任何事情一样,这是一个旅程,而我们在这里取得了巨大的进步。”
  
  “我们显然在Linux系统上全力以赴进行努力,这促使我们以更加开放的方式做事,围绕我们的CAPI技术OpenPower,并认识到摩尔定律已经死亡,真正关注客户的系统级价值,而不是只是处理器级别的价值。”她说。
  
  *IBM的基准
  
  这些声明基于IBM的内部测量,运行1000次扩大的Google Net模型。IBM公司的Power AC922系统将采用40核心处理器(2x20核心芯片)。Power9采用NVLink2.0;2.25GHz,1024GB内存,4×Tesla V100GPU。RedHat企业版Linux7.4的电源Little Endian与CUDA9.1/CUDNN7,采用2x至强E5-2640v4。20个核心处理器(2个10c芯片)/40个线程。采用2.4GHz英特尔至强E5-2640v4,1024GB内存,4×Tesla V100 GPU,Ubuntu16.04,CUDA.9.0/CUDNN7。
