The new High Memory Cluster Eight Extra Large (cr1.8xlarge) instances are designed for applications that have a voracious need for a huge amount of computer memory and bandwidth. The specifications include two Intel E5-2670 processors running at 2.6 GHz with Intel Turbo Boost and NUMA support; 244 GiB of RAM; two 120 GB SSD for instance storage; 10 GB networking with support for Cluster Placement Groups. The instance only supports HVM virtualization and EBS-backed AMIs.
According to a blog post on the Amazon Web Services blog, the cluster instances can be used to run applications that are hungry for lots of memory and that can take advantage of 32 Hyperthreaded cores (16 per processor).
The instance features Turbo Boost, in which the CPU increases clock frequency while keeping an eye on the system’s active cores and processor temperature, in order to deliver increased performance without exceeding the hardware’s documented temperature envelope.
Another feature that gives a substantial gain to performance levels, NUMA (Non-Uniform Memory Access) speeds access to main memory by optimizing for workloads where the majority of requests for a particular block of memory come from one of the two processors.
Amazon Web Services offers a complete set of infrastructure and application services that enable you to run virtually everything in the cloud: from websites and mobile apps, to big data projects and enterprise applications
Amazon has priced the cr1.8xlarge at US$3.50 per hour for Linux instances and $3.831 for Windows instances, both of which will be available from the company’s US East (Northern Virginia) Region.
It may be recalled that in December 2012, Amazon had launched the High Storage Eight Extra Large (hs1.8xlarge) instances, targeted at applications in need of high storage depth and sequential I/O performance. These would include those who require data warehousing and heavy-duty analysis of datasets.
