New – Amazon EC2 X2iezn Situations Powered by the Quickest Intel Xeon Scalable CPU for Reminiscence-Intensive Workloads

Digital Design Automation (EDA) workloads require excessive computing efficiency and a big reminiscence footprint. These workloads are delicate to quicker CPU efficiency and better clock speeds for the reason that quicker efficiency permits extra jobs to be accomplished on the decrease variety of cores. At AWS re:Invent 2020, we launched Amazon EC2 M5zn cases which use second-generation Intel Xeon Scalable (Cascade Lake) processors with an all-core turbo clock frequency of as much as 4.5 GHz, which is the quickest of any cloud occasion.

Our prospects have loved the excessive single-threaded efficiency, high-speed networking, and balanced memory-to-vCPU ratio of EC2 M5zn cases. They’ve requested for cases that may leverage these options whereas additionally offering them a higher reminiscence footprint per vCPU.

As we speak, we’re launching Amazon EC2 X2iezn cases, which use the identical Intel Xeon Scalable processors as M5zn cases, with an all-core turbo clock frequency of 4.5 GHz and as much as 1.5 TiB of reminiscence, which is the quickest of any cloud occasion for EDA workloads. These cases are able to delivering as much as 55 p.c higher price-performance per vCPU in comparison with X1e cases.

X2iezn cases supply 32 GiB of reminiscence per vCPU and can help as much as 48 vCPUs and 1536 GiB of reminiscence. Constructed on the AWS Nitro, they ship as much as 100 Gbps of networking bandwidth and 19 Gbps of devoted Amazon EBS bandwidth to enhance efficiency for EDA purposes.

You might need seen that we’re now utilizing the “i” suffix within the occasion kind to specify that the cases are utilizing an Intel processor, “e” within the memory-optimized occasion household to point prolonged reminiscence, “z” which signifies high-frequency processors, and “n” to help larger community bandwidth as much as 100 Gbps.

X2iezn cases are VPC solely, HVM-only, and EBS-Optimized, with help for Optimize vCPU. As you may see, the memory-to-vCPU ratio on these cases is identical as that of previous-generation X1e cases:

Occasion Title vCPUs RAM (GiB) Community Bandwidth (Gbps) EBS-Optimized Bandwidth (Gbps)
x2iezn.2xlarge 8 256 As much as 25 3.170
x2iezn.4xlarge 16 512 As much as 25 4.750
x2iezn.6xlarge 24 768 50 9.5
x2iezn.8xlarge 32 1024 75 12
x2iezn.12xlarge 48 1536 100 19
x2iezn.steel 48 1536 100 19

Many purchasers will be capable to profit from utilizing X2iezn cases to enhance efficiency and effectivity for his or her EDA workloads. Listed below are some examples:

  • Annapurna Labs examined the X2iezn cases with Calibre’s Design Rule Checking, which has proven a 40 p.c quicker runtime in comparison with X1e cases, and a 25 p.c quicker runtime over R5d cases.
  • Astera Labs is a fabless, cloud-based semiconductor firm growing purpose-built CXL, PCIe, and Ethernet connectivity options for data-centric methods. They have been in a position to see efficiency positive aspects of as much as 25 p.c in comparison with comparable EDA workloads working on R5 cases.
  • Cadence examined the X2iezn cases utilizing their Pegasus True Cloud function, which permits designers to run bodily verification jobs on the cloud and noticed a 50 p.c efficiency enchancment over R5 cases. They see X2iezn cases as a wonderful setting for testing EDA workloads.
  • NXP Semiconductors labored with AWS to run their Calibre and Spectre workloads on Amazon EC2 X2iezn cases, which measured 10-15 p.c larger efficiency utilizing X2iezn cases in comparison with their on-premises, Xeon Gold 6254 with max turbo frequency of 4.0GHz.
  • Siemens EDA labored with AWS to check the brand new Amazon EC2 X2iezn HPC/EDA centered cases with the business efficiency and sign-off chief Calibre evaluating superior node DRC workloads. They have been happy to exhibit efficiency enhancements of as much as 14% utilizing the 4.5 GHz all core turbo frequency of X2iezn cases for all VMs within the run. Moreover, they efficiently demonstrated the usage of a heterogeneous server configuration utilizing the X2iezn as the first node and different decrease reminiscence VMs for distant compute – offering an 11% velocity up and engaging worth. These outcomes confirmed the X2iezn is an effective match for main server EDA workloads for Calibre Bodily and Circuit verification purposes.
  • Synopsys IC Validator gives extremely scalable high-performance bodily verification signoff. They achieved 15 p.c efficiency enchancment, scalability to 1000s of cores, and 30 p.c higher effectivity utilizing IC Validator’s distinctive elastic CPU administration expertise versus R5d cases.

Issues to Know
Listed below are some enjoyable info in regards to the X2iezn cases:

Optimizing CPU—You may disable Intel Hyper-Threading Expertise for workloads that carry out effectively with single-threaded CPUs, like some HPC purposes.

NUMA—You may make use of non-uniform reminiscence entry (NUMA) on x2iezn.12xlarge cases. This superior function is price exploring when you have a deep understanding of your utility’s reminiscence entry patterns.

Accessible Now
Amazon EC2 X2iezn cases at the moment are accessible within the US East (N. Virginia), US West (Oregon), Asia Pacific (Tokyo), and Europe (Eire) Areas. You should utilize On-Demand Situations, Reserved Situations, Financial savings Plan, and Spot Situations. Devoted Situations and Devoted Hosts are additionally accessible.
