DC-SIMD : Dynamic communication for SIMD processors [PDF]
2008 IEEE International Symposium on Parallel and Distributed Processing, 2008 SIMD (single instruction multiple data)-type processors have been found very efficient in image processing applications, because their repetitive structure is able to exploit the huge amount of data-level parallelism in pixel-type operations, operating at a relatively low energy consumption rate.

Maximizing SIMD resource utilization in GPGPUs with SIMD lane permutation [PDF]
Proceedings of the 40th Annual International Symposium on Computer Architecture, 2013 Current GPUs maintain high programmability by abstracting the SIMD nature of the hardware as independent concurrent threads of control with hardware responsible for generating predicate masks to utilize the SIMD hardware for different flows of control.

SIMD@OpenMP : a programming model approach to leverage SIMD features [PDF]
, 2023 SIMD instruction sets are a key feature in current general purpose and high performance architectures. SIMD instructions apply in parallel the same operation to a group of data, commonly known as vector. A single SIMD/vector instruction can, thus, replace a sequence of scalar instructions. Consequently, the number of instructions can be greatly reduced

Revisiting SIMD Programming [PDF]
, 2008 Massively parallel SIMD array architectures are making their way into embedded processors. In these architectures, a number of identical processing elements having small private storage and using asynchronous I/O for accessing large shared memory executes the same instruction in lockstep.

Preterm birth, socioeconomic status, and white matter development across childhood [PDF]
Developmental Cognitive NeurosciencePreterm birth and socioeconomic status (SES) are associated with brain development in early life, but the contribution of each over time is uncertain. We examined the effects of gestational age (GA) and SES on white matter microstructure in the neonatal ...

Minotaur: A SIMD-Oriented Synthesizing Superoptimizer [PDF]
Proc. ACM Program. Lang., 2023 A superoptimizing compiler—one that performs a meaningful search of the program space as part of the optimization process—can find optimization opportunities that are missed by even the best existing optimizing compilers.

SIMD-Matcher: A SIMD-based Arbitrary Matching Framework [PDF]
ACM Transactions on Architecture and Code Optimization, 2022 Packet classification methods rely upon matching packet content/header against pre-defined rules, which are generated by network applications and their configurations. With the rapid development of network technology and the fast-growing network applications, users seek more enhanced, secure, and diverse network services.
