However, these models bring notable challenges, even to expert programmers. Indeed, fully exploiting the power of hardware accelerators with CUDA-like code often requires significant code optimization e.ort. While this development can certainly yield high performance, it is desirable for some programmers to avoid the explicit management of device initialization and data transfer between memory levels. To this end, high-level models for accelerator programming, like OpenMP and OpenACC, have become an important research direction. With these models, programmers only need to annotate their C/C++ code to indicate which code portion is to be executed on the device and how data maps between host and device.","PeriodicalId":7093,"journal":{"name":"ACM Commun.

In the vector space of (noncommutative) polynomials which is equipped q-deformed quasi-shuffle products and concatenation product [1, 2], we compute the bases in duality and express an arbitrary homogeneous polynomial in terms of these bases. Moreover, due to our algorithms, we can represent structure of MZVs on the transcendence bases in terms of irreducible elements [4].
