Efficient Reuse Distance Analysis of Multicore Scaling for Loop-Based Parallel Programs
Meng-Ju Wu, Donald Yeung
Article No.: 1
DOI: 10.1145/2427631.2427632

Reuse Distance (RD) analysis is a powerful memory analysis tool that can potentially help architects study multicore processor scaling. One key obstacle, however, is that multicore RD analysis requires measuring Concurrent Reuse Distance...

Aggressive Datacenter Power Provisioning with Batteries
Sriram Govindan, Di Wang, Anand Sivasubramaniam, Bhuvan Urgaonkar
Article No.: 2
DOI: 10.1145/2427631.2427633

Datacenters spend $10--25 per watt in provisioning their power infrastructure, regardless of the watts actually consumed. Since peak power needs arise rarely, provisioning power infrastructure for them can be expensive. One can, thus, aggressively...

TritonSort: A Balanced and Energy-Efficient Large-Scale Sorting System
Alexander Rasmussen, George Porter, Michael Conley, Harsha V. Madhyastha, Radhika Niranjan Mysore, Alexander Pucher, Amin Vahdat
Article No.: 3
DOI: 10.1145/2427631.2427634

We present TritonSort, a highly efficient, scalable sorting system. It is designed to process large datasets, and has been evaluated against as much as 100TB of input data spread across 832 disks in 52 nodes at a rate of 0.938TB/min. When...
