Intel® On Demand

Starting from the 4th Gen Intel Xeon Scalable processors introduce new embedded accelerators to add even more processing capability: Basic capabilities are available at the initial processor installation, while others remain inactivated. As development environment and tasks evolve, computing demands may accelerate and require leverage of the previously inactivated processor capabilities. In such cases, user can select desired processor capabilities and activate them though Intel On Demand feature—a feature that allows user to customize processor capabilities according to environment and tasks at hand. Currently the following features are available on different CPUs:

  • Intel Quick Assist Technology (Intel QAT)1

    Intel® QAT which helps free up processor cores by offloading encryption, decryption, and compression so systems can serve a larger number of clients or use less power. With Intel QAT, 4th gen Intel Xeon Scalable processors are the highest performance CPUs that can compress and encrypt in a single data flow.

  • Intel Dynamic Load Balancer (Intel DLB)2

    Intel DLB is a hardware managed system of queues and arbiters connecting producers and consumers. It is a PCI device envisaged to live in the server CPU uncore and can interact with software running on cores, and potentially with other devices.

  • Inte Data Streaming Accelerator (Intel DSA)1

    Intel DSA drives high performance for storage, networking, and data-intensive workloads by improving streaming data movement and transformation operations. Designed to offload the most common data movement tasks that cause overhead in data center-scale deployments, Intel DSA helps speed up data movement across the CPU, memory, caches, all attached memory, storage, and network devices.

  • Intel In Memory Accelerator (Intel IAA)1

    Intel IAA helps run database and analytics workloads faster, with potentially greater power efficiency. This built-in accelerator increases query throughput and decreases the memory footprint for in-memory database and big data analytics workloads. Intel IAA is ideal for in-memory databases, and source databases.

  • Intel Software Guard Extensions (Intel SGX) 512 GB3

    Intel® SGX offers hardware-based memory encryption that isolates specific application code and data in memory. Intel SGX allows user-level code to allocate private regions of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels.
