Methods, apparatus, systems, and articles of manufacture are disclosed for dynamic load balancing for multi-core computing environments. An example apparatus includes a first and a plurality of second cores of a processor, and circuitry in a die of the processor separate from the first and the second cores, the circuitry to enqueue identifiers in one or more queues in the circuitry associated with respective ones of data packets of a packet flow, allocate one or more of the second cores to dequeue first ones of the identifiers in response to a throughput parameter of the first core not satisfying a throughput threshold to cause the one or more of the second cores to execute one or more operations on first ones of the data packets, and provide the first ones to one or more data consumers to distribute the first data packets.

Dynamic load balancing for multi-core computing environments

Methods, apparatus, systems, and articles of manufacture are disclosed for hardware queue scheduling for multi-core computing environments. An example apparatus includes a first core and a second core of a processor, and circuitry in a die of the processor, at least one of the first core or the second core included in the die, the at least one of the first core or the second core separate from the circuitry, the circuitry to enqueue an identifier to a queue implemented with the circuitry, the identifier associated with a data packet, assign the identifier in the queue to a first core of the processor, and in response to an execution of an operation on the data packet with the first core, provide the identifier to the second core to cause the second core to distribute the data packet.

Hardware queue scheduling for multi-core computing environments

Examples provide an application program interface or manner of negotiating locking or pinning or unlocking or unpinning of a cache region by which an application, software, or hardware. A cache region can be part of a level-1, level-2, lower or last level cache (LLC), or translation lookaside buffer (TLB) are locked (e.g., pinned) or unlocked (e.g., unpinned). A cache lock controller can respond to a request to lock or unlock a region of cache or TLB by indicating that the request is successful or not successful. If a request is not successful, the controller can provide feedback indicating one or more aspects of the request that are not permitted. The application, software, or hardware can submit another request, a modified request, based on the feedback to attempt to lock a portion of the cache or TLB.

Controller for locking of selected cache regions

Methods, apparatus, systems and machine-readable storage media of an edge computing device using an edge server CPU with dynamic deterministic scaling is disclosed. A processing circuitry arrangement includes processing circuitry with processor cores operating at a center base frequency and memory. The memory includes instructions configuring the processing circuitry to configure a first set of the processor cores of the CPU to switch the operating at the center base frequency to operating at a first modified base frequency, and a second set of the processor cores to switch the operating at the center base frequency to operating at a second modified base frequency. A same processor core within the first set or the second set can be configured to switch operating between the first modified base frequency or the second modified base frequency.

Edge server CPU with dynamic deterministic scaling

There is disclosed in one example a computing apparatus, including: a cache; a caching agent (CA); an integrated input/output (IIO) block to provide a cache coherent interface to a peripheral device at a first speed; a core configured to poll an address within the cache via the CA, wherein the address is to receive incoming data from the peripheral device via the IIO, and wherein the core is capable of polling the address at a second speed substantially greater than the first speed; and a hardware uncore agent configured to: identify a collision between the core and the IIO including determining that the core is polling the address at a rate that is determined to interfere with access to the address by the IIO; and throttle the core's access to the address.
