Performance Characterization of HTAP Workloads

Anastasia Ailamaki, Sandhya Dwarkadas, Utku Sirin

Hybrid Transactional and Analytical Processing (HTAP) systems have become popular in the past decade. HTAP systems allow running transactional and analytical processing workloads on the same data and hardware. As a result, they suffer from workload interfe ...

IEEE COMPUTER SOC2021

We analyze an Alpha 21264-like Globally–Asynchronous, Locally–Synchronous (GALS) processor organized as a Multiple Clock Domain (MCD) microarchitecture and identify the architectural features of the processor that influence the limited performance degradat ...

Dynamically Tuning Processor Resources with Adaptive Processing

Sandhya Dwarkadas

The productivity of modern society has become inextricably linked to its ability to produce energy-efficient computing technology. Increasingly sophisticated mobile computing systems, powered for hours solely by batteries, continue to proliferate rapidly t ...

Dynamic Frequency and Voltage Scaling for a Multiple-Clock-Domain Microprocessor

Sandhya Dwarkadas

Multiple clock domains is one solution to the increasing problem of propagating the clock signal across increasingly larger and faster chips. The ability to independently scale frequency and voltage in each domain creates a powerful means of reducing power ...

2003

We describe the design, analysis, and performance of an on-line algorithm to dynamically control the frequency/voltage of a Multiple Clock Domain (MCD) microarchitecture. The MCD microarchitecture allows the frequency/voltage of micrprocessor regions to be ...

Managing Static Leakage Energy in Microprocessor Functional Units

Sandhya Dwarkadas

Static energy due to subthreshold leakage current is projected to become a major component of the total energy in high performance microprocessors. Many studies so far have examined and proposed techniques to reduce leakage in on-chip storage structures. I ...

Integrating Adaptive On-Chip Storage Structures for Reduced Dynamic Power

Sandhya Dwarkadas

Energy efficiency in microarchitectures has become a necessity. Significant dynamic energy savings can be realized for adaptive storage structures such as caches, issue queues, and register files by disabling unnecessary storage resources. Prior studies ha ...

Combining Compile-Time and Run-Time Support for Efficient Distributed Shared Memory

Willy Zwaenepoel, Sandhya Dwarkadas

We describe an integrated compile-time and run-time system for efficient shared memory parallel computing on distributed memory machines. The combined system presents the user with a shared memory programming model, with its well-known benefits in terms of ...

Adaptive Protocols for Software Distributed Shared Memory

Willy Zwaenepoel, Sandhya Dwarkadas

We demonstrate the benefits of software shared memory protocols that adapt at run-time to the memory access patterns observed in the applications. This adaptation is automatic, no user annotations are required, and does not rely on compiler support or spec ...

Quantifying the Performance Differences Between PVM and TreadMarks

Willy Zwaenepoel, Sandhya Dwarkadas

We compare two systems for parallel programming on networks of workstations: Parallel Virtual Machine (PVM) a message passing system, and TreadMarks, a software distributed shared memory (DSM) system. We present results for eight applications that were imp ...
