Abstract: The present disclosure describes techniques for offloading computation based on an extended instruction set architecture (ISA). The extended ISA may be created based on identifying functions executed multiple times by a central processing unit (CPU). The extended ISA may comprise hashes corresponding to the functions and identifiers of extended operations associated with the functions. The extended operations may be converted from original operations of the functions. The extended operations may be executable by a storage device. The storage device may be associated with at least one computational core. Code may be synthesized based at least in part on the extended ISA. Computation of the synthesized code may be offloaded into the storage device.

Abstract: The present disclosure describes techniques for offloading data processing and knowledge synthesis. A set of flags may indicate information about the memory pages in a first memory and may be manageable by at least one central processing unit (CPU). A memory page may be flushed to a second memory if the memory page is associated with a first flag. The first flag may indicate that the memory page is ready to be flushed to the second memory. The second memory may be configured to store a sequence of states of each of the memory pages. Data patterns and relations among the data patterns may be determined by data processing units (DPUs) based on the sequence of states of each of the memory pages. A knowledge base may be built in a third memory based on the data patterns and the relations among the data patterns.

Abstract: The present disclosure describes techniques for implementing instant corruption detection and recovery. A plurality of streams may be created in a storage device. Each of the plurality of streams may contain a sequence of metadata nodes of a same type. Each of the plurality of streams may maintain an initial state, a sequence of delta modifications to the initial state, and an actual state for each of the sequence of metadata nodes. A checking and recovery function associated with a particular stream among the plurality of streams may be determined. The checking and recovery function may comprise checking logic configured to detect corruptions by checking modification operations associated with metadata nodes in the particular stream. The checking and recovery function may further comprise recovery logic configured to perform recoveries from the corruptions. The checking and recovery function associated with the particular stream may be implemented in the storage device.
