Device and method for cache utilization aware data compression

Patent Das, Shomit N.; Punniyamurthy, Kishore; Tomei, Matthew; ...

A processing device is provided which includes memory and at least one processor. The memory includes main memory and cache memory in communication with the main memory via a link. The at least one processor is configured to receive a request for a cache line and read the cache line from main memory. The at least one processor is also configured to compress the cache line according to a compression algorithm and, when the compressed cache line includes at least one byte predicted not to be accessed, drop the at least one byte from the compressed cache line based onmore » « less

Locality-aware and sharing-aware cache coherence for collections of processors

Patent Farmahini Farahani, Amin; Jayasena, Nuwan

A cache coherence technique for operating a multi-processor system including shared memory includes allocating a cache line of a cache memory of a processor to a memory address in the shared memory in response to execution of an instruction of a program executing on the processor. The technique includes encoding a shared information state of the cache line to indicate whether the memory address is a shared memory address shared by the processor and a second processor, or a private memory address private to the processor, in response to whether the instruction is included in a critical section of themore » « less

Network-aware cache coherence protocol enhancement

Patent Roberts, David A.; Fatehi, Ehsan

A non-uniform memory access system includes several nodes that each have one or more processors, caches, local main memory, and a local bus that connects a node's processor(s) to its memory. The nodes are coupled to one another over a collection of point-to-point interconnects, thereby permitting processors in one node to access data stored in another node. Memory access time for remote memory takes longer than local memory because remote memory accesses have to travel across a communications network to arrive at the requesting processor. In some embodiments, inter-cache and main-memory-to-cache latencies are measured to determine whether it would bemore » « less

Constant time worker thread allocation via configuration caching

Patent Eichenberger, Alexandre E; O'Brien, John K. P.

Mechanisms are provided for allocating threads for execution of a parallel region of code. A request for allocation of worker threads to execute the parallel region of code is received from a master thread. Cached thread allocation information identifying prior thread allocations that have been performed for the master thread are accessed. Worker threads are allocated to the master thread based on the cached thread allocation information. The parallel region of code is executed using the allocated worker threads.

System, method, and computer program product for warming a cache for a task launch

Patent Ricketts, Scott; Wang, Nicholas; Gadre, Shirish; ...

A system, method, and computer program product for warming a cache for a task launch is described. The method includes the steps of receiving a task data structure that defines a processing task, extracting information stored in a cache warming field of the task data structure, and, prior to executing the processing task, generating a cache warming instruction that is configured to load one or more entries of a cache storage with data fetched from a memory.
