Reference locality is vital to the performance of parallel Garbage Collection (GC) running on Non-Uniform Memory Access (NUMA) machines. A GC thread may trace remotely placed objects that descend from the root set or, for load balance, a GC thread may ...

From a trace of data accesses, it is possible to calculate an affinity hierarchy that groups related data together. Combining this hierarchy with the extremely common hash table, there is an opportunity to both improve cache performance and enable novel ...

TCMalloc [9] is an open-source memory allocator. Its use of thread-local caches of free objects enables most allocations/deallocations to be satisfied from thread-local heaps not requiring locks, making it a highly scalable memory allocator for multi-...

Application performance on multicore processors is seldom constrained by the speed of floating point or integer units. Much more often, limitations are caused by the memory subsystem, particularly shared resources such as last level caches or memory ...

Energy harvesting enables intermittently powered devices to compute without built-in power. But frequent power failures, combined with nonvolatile memory intended to protect computational state, introduce strange control flow that turns sequential code ...

This paper introduces O-structures, a novel architectural memory element that can be used to facilitate parallelism in task-based execution models. Much like register renaming, each write to an O-structure creates a new version of program memory at that ...

It is very difficult to define a programming language memory model for shared variables that both

• allows programmers to take full advantage of weakly-ordered memory operations, but still

• correctly disallows so-called "out-of-thin-air" results, i.e. ...

The gap between processing and storage speeds remains a concern for computer system designers and application developers. This disparity can be bridged in part by eliminating unnecessary stores, thereby reducing the amount of traffic that flows from the ...
