Linebacker: Preserving Victim Cache Lines in Idle Register Files of GPUs

Yunho Oh

Modern GPUs suffer from cache contention due to the limited cache size that is shared across tens of concurrently running warps. To increase the per-warp cache size prior techniques proposed warp throttling which limits the number of active warps. Warp thr ...

Exploiting Compute Caches for Memory Bound Vector Operations

Paolo Ienne, Gabriel Falcao Paiva Fernandes, João Miguel Morgado Pereira Vieira

To reduce the average memory access time, most current processors make use of a multilevel cache subsystem. However, despite the proven benefits of such cache structures in the resulting throughput, conventional operations such as copy, simple maps and red ...

A Cache-Assisted Scratchpad Memory for Multiple-Bit-Error Correction

Hossein Asadi, Nooshin Sadat Mirzadeh

Scratchpad memory (SPM) is widely used in modern embedded processors to overcome the limitations of cache memory. The high vulnerability of SPM to soft errors, however, limits its usage in safety-critical applications. This paper proposes an efficient faul ...

ADDICT: Advanced Instruction Chasing for Transactions

Anastasia Ailamaki, Pinar Tözün

Recent studies highlight that traditional transaction processing systems utilize the micro-architectural features of modern processors very poorly. L1 instruction cache and long-latency data misses dominate execution time. As a result, more than half of th ...

A Primer on Hardware Prefetching

Babak Falsafi

Since the 1970’s, microprocessor-based digital platforms have been riding Moore’s law, allowing for doubling of density for the same area roughly every two years. However, whereas microprocessor fabrication has focused on increasing instruction execution r ...

Enabling efficient OS paging for main-memory OLTP databases

Anastasia Ailamaki, Radu Ioan Stoica

Even though main memory is becoming large enough to fit most OLTP databases, it may not always be the best option. OLTP workloads typically exhibit skewed access patterns where some records are hot (frequently accessed) but many records are cold (infrequen ...

Reducing OLTP Instruction Misses With Thread Migration

Anastasia Ailamaki, Pinar Tözün

During an instruction miss a processor is unable to fetch instructions. The more frequent instruction misses are the less able a modern processor is to find useful work to do and thus performance suffers. Online transaction processing (OLTP) suffers from h ...

Why Nothing Matters: The Impact of Zeroing

Jennifer Bedke Sartor, Xi Yang

Memory safety defends against inadvertent and malicious misuse of memory that may compromise program correctness and security. A critical element of memory safety is zero initialization. The direct cost of zero initialization is surprisingly high: up to 12 ...

We introduce a novel multi-resource allocator to dynamically allocate resources for database servers running on virtual storage. Multi-resource allocation involves proportioning the database and storage server caches, and the storage bandwidth between appl ...

Exploration of Memory Hierarchy Configurations for Efficient Garbage Collection on High-Performance Embedded Systems

David Atienza Alonso

Modern embedded devices (e.g., PDAs, mobile phones) are now incorporating Java as a very popular implementation language in their designs. These new embedded systems include multiple applications that are dynamically launched by the user, which can produce ...
