Abstract: Methods for frequency scaling for per-core accelerator assignments and associated apparatus. A processor includes a CPU (central processing unit) having multiple cores that can be selectively configured to support frequency scaling and instruction extensions. Under this approach, some cores can be configured to support a selective set of AVX instructions (such as AVX3/5G-ISA instructions) and/or AMX instructions, while other cores are configured to not support these AVX/AMX instructions. In one aspect, the selective AVX/AMX instructions are implemented in one or more ISA extension units that are separate from the main processor core (or otherwise comprises a separate block of circuitry in a processor core) that can be selectively enabled or disabled. This enables cores having the separate unit(s) disabled to consume less power and/or operate at higher frequencies, while supporting the selective AVX/AMX instructions using other cores. These capabilities enhance performance and provides flexibility to handle a variety of applications requiring use of advanced AVX/AMX instructions to support accelerated workloads.

Abstract: Self-healing networks of Infrastructure Processing Units (IPUs) and associated methods and apparatus. The self-healing IPUs manage other processing units (XPU) clusters by seamlessly migrating the IPU responsibilities to another IPU in the networked environment (e.g., data center) that may be available when an IPU failures or becomes unavailable. A central Resource Manager is used to monitors the health of the IPUs in the data center and in the event of in IPU failure, locates another IPU and assigns it to take over the failed IPU's functions. Replacement and workload migration of a failed XPU in an IPU managed XPU cluster with a remote XPU that is network connected is also supported. The IPU monitors the health of the XPUs in its cluster an informs the Resource Manager of an XPU failure which locates another XPU in the data center and assigns it to the cluster that has the failed XPU.
