1 Stable Performance for Cc-numa Using First Touch Page Placement and Reactive Proxies
A key problem for shared-memory systems is unpredictable performance. A critical in uence on performance is page placement: a poor choice of home node can severely degrade application performance because of the increased latency of accessing remote rather than local data. Two approaches to page placement are the simple policies \ rst-touch" and \round-robin", but neither of these policies suits...
متن کاملPinning down NuMA
and colleagues have found that cells need a particular transcription factor to survive in the hypoxic interior of developing bones. The critical activity of hypoxia-inducible factor 1 ␣ (HIF-1 ␣), they say, is probably its induction of a glycolytic metabolism appropriate to a R HIF-1␣ prevents cell death despite hypoxia (red) in a wild-type tibia. low oxygen environment. Without this metabolic ...
متن کاملInterprocessor Invocation on a NUMA . . .
On a distributed shared memory machine, the problem of minimizing accesses to remote memory modules is crucial for obtaining high performance. We describe an object-based, parallel programming system called OSMIUM to support experiments with mechanisms for performing invocations on remote objects. The mechanisms we have studied include: non-cached access to remote memory, data migration, and fu...
متن کاملNUMA-Aware Multicore Matrix Multiplication
A novel user-level scheduling, along with a specific data alignment method is presented for matrix multiplication in cache-coherent Non-Uniform Memory Access (ccNUMA) architectures. Addressing the data locality problem that occurs in such systems alleviates memory bottlenecks in problems with large input data sets. It is shown experimentally that a large number of cache misses occur when using ...
متن کاملMAP-numa: Access Patterns Used to Characterize the NUMA Memory Access Optimization Techniques and Algorithms
Some typical memory access patterns are provided and programmed in C, which can be used as benchmark to characterize the various techniques and algorithms aim to improve the performance of NUMA memory access. These access patterns, called MAP-numa (Memory Access Patterns for NUMA), currently include three classes, whose working data sets are corresponding to 1-dimension array, 2-dimension matri...
