Electronic Design Automation (EDA) workloads require high computing performance and a large memory footprint. These workloads are sensitive to faster CPU performance and higher clock speeds since the faster performance allows more jobs to be completed on the lower number of cores. At AWS re:Invent 2020, we launched Amazon EC2 M5zn instances which use second-generation Intel Xeon Scalable (Cascade Lake) processors with an all-core turbo clock frequency of up to 4.5 GHz, which is the fastest of any cloud instance.
Our customers have enjoyed the high single-threaded performance, high-speed networking, and balanced memory-to-vCPU ratio of EC2 M5zn instances. They have asked for instances that will leverage these features while also providing them a greater memory footprint per vCPU.
Today, we are launching Amazon EC2 X2iezn instances, which use the same Intel Xeon Scalable processors as M5zn instances, with an all-core turbo clock frequency of 4.5 GHz and up to 1.5 TiB of memory, which is the fastest of any cloud instance for EDA workloads. These instances are capable of delivering up to 55 percent better price-performance per vCPU compared to X1e instances.
X2iezn instances offer 32 GiB of memory per vCPU and will support up to 48 vCPUs and 1536 GiB of memory. Built on the AWS Nitro, they deliver up to 100 Gbps of networking bandwidth and 19 Gbps of dedicated Amazon EBS bandwidth to improve performance for EDA applications.
You might have noticed that we’re now using the “i” suffix in the instance type to specify that the instances are using an Intel processor, “e” in the memory-optimized instance family to indicate extended memory, “z” which indicates high-frequency processors, and “n” to support higher network bandwidth up to 100 Gbps.
X2iezn instances are VPC only, HVM-only, and EBS-Optimized, with support for Optimize vCPU. As you can see, the memory-to-vCPU ratio on these instances is the same as that of previous-generation X1e instances:
|Instance Name||vCPUs||RAM (GiB)||Network Bandwidth (Gbps)||EBS-Optimized Bandwidth (Gbps)|
|x2iezn.2xlarge||8||256||Up to 25||3.170|
|x2iezn.4xlarge||16||512||Up to 25||4.750|
Many customers will be able to benefit from using X2iezn instances to improve performance and efficiency for their EDA workloads. Here are some examples:
Things to Know
Here are some fun facts about the X2iezn instances:
Optimizing CPU—You can disable Intel Hyper-Threading Technology for workloads that perform well with single-threaded CPUs, like some HPC applications.
NUMA—You can make use of non-uniform memory access (NUMA) on x2iezn.12xlarge instances. This advanced feature is worth exploring if you have a deep understanding of your application’s memory access patterns.
Amazon EC2 X2iezn instances are now available in the US East (N. Virginia), US West (Oregon), Asia Pacific (Tokyo), and Europe (Ireland) Regions. You can use On-Demand Instances, Reserved Instances, Savings Plan, and Spot Instances. Dedicated Instances and Dedicated Hosts are also available.
