Toward a Universal Cryptographic Accelerator

Srinivas Devadas;Daniel Sanchez

Computer
Year: 2025 | Volume: 58, Issue: 1 | Magazine Article |
Cyberphysical systems have disseminated devices that can be untrustworthy or compromised. Nevertheless, the privacy and integrity of computation and data can be guaranteed through cryptographic protocols. We address the computational burden posed by cryptography, and argue for a synergistic approach of designing programmable hardware accelerators for cryptography, followed by tailoring cryptograph...Show More

Terminus: A Programmable Accelerator for Read and Update Operations on Sparse Data Structures

Hyun Ryong Lee;Daniel Sanchez

2024 57th IEEE/ACM International Symposium on Microarchitecture (MICRO)
Year: 2024 | Conference Paper |
Sparse data structures like hash tables, trees, or compressed tensors are ubiquitous, but operations on these structures are expensive and inefficient on current systems. Prior work has proposed hardware acceleration for these operations, but these techniques have two key shortcomings: they limit the types of data structures they support, and they focus on reads but do not support fine-grained upd...Show More

Azul: An Accelerator for Sparse Iterative Solvers Leveraging Distributed On-Chip Memory

Axel Feldmann;Courtney Golden;Yifan Yang;Joel S. Emer;Daniel Sanchez

2024 57th IEEE/ACM International Symposium on Microarchitecture (MICRO)
Year: 2024 | Conference Paper |
Solving sparse systems of linear equations is a fundamental primitive in many numeric algorithms. Iterative solvers provide an efficient way of solving large, highly sparse systems. However, iterative solvers are inefficient on existing architectures because they perform computations with (1) poor short-term reuse, which causes frequent off-chip memory traffic; and (2) challenaing data dependences...Show More

2024 57th IEEE/ACM International Symposium on Microarchitecture (MICRO)
Year: 2024 | Conference Paper |
Cited by: Papers (1)
Zero-Knowledge Proofs (ZKPs) are a cryptographic tool that enables one party (a prover) to prove to another (a verifier) that a statement is true, without requiring the prover to disclose any data to the verifier. ZKPs have many use cases, such as letting clients delegate computation to servers with cryptographic correctness guarantees, while enabling the server to use secret data in these computa...Show More

2023 IEEE International Symposium on High-Performance Computer Architecture (HPCA)
Year: 2023 | Conference Paper |
Cited by: Papers (14)
Sparse CNNs dramatically reduce computation and storage costs over dense ones. But sparsity also makes CNNs more data-intensive, as each value is reused fewer times. Thus, current sparse CNN accelerators, which process one layer at a time, are bottlenecked by memory traffic.We present ISOSceles, a new sparse CNN accelerator that dramatically reduces data movement through inter-layer pipelining: ov...Show More

Irregular applications are increasingly common in diverse domains, like graph analytics and sparse linear algebra. Accelerating these applications is challenging because of their unpredictable data reuse and control flow.

Year: 2022 | Conference Paper |
Cited by: Papers (2)
Benchmarks that closely match the behavior of production workloads are crucial to design and provision computer systems. However, current approaches fall short: First, open-source benchmarks use public datasets that cause different behavior from production workloads. Second, blackbox workload cloning techniques generate synthetic code that imitates the target workload, but the resulting program fa...Show More

IEEE Micro
Year: 2022 | Volume: 42, Issue: 4 | Magazine Article |
Fully homomorphic encryption (FHE) allows computing on encrypted data, enabling secure offloading of computation to untrusted servers. Though it provides ideal security, FHE is prohibitively expensive when executed in software. These overheads are a major barrier to FHE's widespread adoption. We present F1, the first FHE accelerator that is capable of executing full FHE programs. F1 builds on an i...Show More

Year: 2021 | Volume: 41, Issue: 3 | Magazine Article |
Cited by: Papers (1)
We offer the first security analysis of cache compression, a promising architectural technique that is likely to appear in future mainstream processors. We find that cache compression has novel security implications because the compressibility of a cache line reveals information about its contents. Compressed caches introduce a new side channel that is especially insidious, as simply storing data ...Show More

2020 ACM/IEEE 47th Annual International Symposium on Computer Architecture (ISCA)
Year: 2020 | Conference Paper |
Cited by: Papers (21)
Multicores are now ubiquitous, but programmers still write sequential code. Speculative parallelization is an enticing approach to parallelize code while retaining the ease of sequential programming, making parallelism pervasive. However, prior speculative parallelizing compilers and architectures achieved limited speedups due to high costs of recovering from misspeculation and hardware scalabilit...Show More

Exploiting Locality in Graph Analytics through Hardware-Accelerated Traversal Scheduling

Anurag Mukkara;Nathan Beckmann;Maleen Abeydeera;Xiaosong Ma;Daniel Sanchez

2018 51st Annual IEEE/ACM International Symposium on Microarchitecture (MICRO)
Year: 2018 | Conference Paper |
Graph processing is increasingly bottlenecked by main memory accesses. On-chip caches are of little help because the irregular structure of graphs causes seemingly random memory references. However, most real-world graphs offer significant potential locality—it is just hard to predict ahead of time. In practice, graphs have well-connected regions where relatively few vertices share edges with many...Show More

Adaptive Scheduling for Systems with Asymmetric Memory Hierarchies

Po-An Tsai;Changping Chen;Daniel Sanchez

2018 51st Annual IEEE/ACM International Symposium on Microarchitecture (MICRO)
Year: 2018 | Conference Paper |
Cited by: Papers (22)
Conventional multicores rely on deep cache hierarchies to reduce data movement. Recent advances in die stacking have enabled near-data processing (NDP) systems that reduce data movement by placing cores close to memory. NDP cores enjoy cheaper memory accesses and are more area-constrained, so they use shallow cache hierarchies instead. Since neither shallow nor deep hierarchies work well for all a...Show More

Harmonizing Speculative and Non-Speculative Execution in Architectures for Ordered Parallelism

2018 51st Annual IEEE/ACM International Symposium on Microarchitecture (MICRO)
Year: 2018 | Conference Paper |
Cited by: Papers (7)
Multicore systems should support both speculative and non-speculative parallelism. Speculative parallelism is easy to use and is crucial to scale many challenging applications, while non-speculative parallelism is more efficient and allows parallel irrevocable actions (e.g., parallel I/O). Unfortunately, prior techniques are far from this goal. Hardware transactional memory (HTM) systems support s...Show More

We present Hotpads, a new memory hierarchy designed from the ground up for modern, memory-safe languages like Java, Go, and Rust. Memory-safe languages hide the memory layout from the programmer. This prevents memory corruption bugs and enables automatic memory management. Hotpads extends the same insight to the memory hierarchy: it hides the memory layout from software and takes control over it, ...Show More

2018 IEEE International Symposium on High Performance Computer Architecture (HPCA)
Year: 2018 | Conference Paper |
Cache partitioning is now available in commercial hardware. In theory, software can leverage cache partitioning to use the last-level cache better and improve performance. In practice, however, current systems implement way-partitioning, which offers a limited number of partitions and often hurts performance. These limitations squander the performance potential of smart cache management. We presen...Show More

Memoization improves performance and saves energy bycaching and reusing the outputs of repetitive computations. Prior work has proposed software and hardware memoization techniques, but both have significant drawbacks. Software memoization suffers from high runtime overheads, and is thus limited to long computations. Conventional hardware memoization techniques achieve low overheads and can memoiz...Show More

Caches are traditionally organized as a rigid hierarchy, with multiple levels of progressively larger and slower memories. Hierarchy allows a simple, fixed design to benefit a wide range of applications, since working sets settle at the smallest (i.e., fastest and most energy-efficient) level they fit in. However, rigid hierarchies also add overheads, because each level adds latency and energy eve...Show More
