This week, Intel revealed additional details about the software-defined silicon (SDSi) capabilities of its next-generation Xeon Scalable processors, as well as the official brand name for the technology. The technology, casually dubbed “Intel On Demand,” allows a system administrator to enable dedicated accelerators integrated into his Intel’s 4th Generation Xeon Scalable “Sapphire Rapids” processors.
Intel releases this week SDSi patch update (opens in new tab) It was reportedly integrated into Linux 5.18, revealing more details about this feature than the patch itself. phonics (opens in new tab)Software that enables certain built-in acceleration features of Intel’s 4th Gen Xeon Scalable Sapphire Rapids (opens in new tab) The CPU (and possibly its successor) is called Intel On Demand and does the following:
- Detects features that are physically present on a particular CPU.
- Suggest to the administrator to activate them.
- Allows administrators to rate how often features are used.
The main conspiracy regarding the Intel On Demand mechanism remains a mystery. I don’t know which features Intel will enable after purchase. However, I understand that Intel’s Sapphire Rapids has some specific acceleration technologies. This list includes Advanced Matrix Extensions (AMX), Dynamic Load Balancer (DLB), Intel Data Streaming Accelerator (DSA), Intel In-Memory Analytics Accelerator (IAA), and Intel QuickAssist Technology (QAT), Accelerate specific workloads.
This program enables access to the CPU’s interfaces from Intel’s SDSi or, where appropriate, Intel On Demand’s previously disclosed beans, and uses Authentication Key Certificate (AKC) and Capability Activation Payload (CAP) licenses. I already know to allow silicon features by We also know that this program allows you to enable certain features on specific CPU sockets instead of all processors in your system or the data center itself.
On the other hand, the fact that software has to detect what features the processor physically supports and hide what it doesn’t is a reason that not all Intel Xeon Scalable ‘Sapphire Rapids’ processors are created equal. means no. Some CPU models may not support certain features using Intel On Demand Software.
Not everyone needs AMX, DLB, DSA, IAA, and QAT all at once. But which one will be enabled by default on all his SKUs and will need to be activated using the IOD software is on his January 10th when Intel officially announces its next-generation Xeon Scalable CPUs. It will probably become clear.
