Hybrid MPI+ threads programming is gaining prominence, but, in practice, applications
perform slower with it compared to the MPI everywhere model. The most critical challenge to …

Background A precise map of the metabolic fluxome, the closest surrogate to the
physiological phenotype, is becoming progressively more important in the metabolic …

Supercomputing applications are increasingly adopting the MPI+ threads programming
model over the traditional “MPI everywhere” approach to better handle the disproportionate …

Barrier synchronization is a well known operation in parallel processing that can be an
obstacle for getting performance in parallel programs, particularly for high thread counts …

同步操作在保证多核处理器线程的数据一致性和正确性等方面起着重要作用.
随着处理器内核数量的不断增加, 同步操作的开销也越来越大. 栅栏同步是并行应用中多核同步 …

Sharing data among asynchronous processes is considered to be a hard systems problem
in multithreaded modern shared-memory multicore systems. Throughout the literature …

In a general-purpose multicore parallel multithreaded environment, multiple threads work
simultaneously to finish a task faster. Usually, threads need to communicate with each other …

Synchronization plays an important role in ensuring data consistency and correctness of
multicore processor threads. As the number of processor cores increases, the cost of …

Big data systems such as relational databases, data science platforms, and scientific
workflows all process queries over large and complex datasets. Skew is common in these …

Supercomputing applications rely on strong scaling to achieve faster results on a larger
number of processing units. But, at the strong-scaling limit, where communication is a …
