39.2.2 A Work-Efficient Parallel ScanOur implementation of scan from Section 39.2.1 would probably perform very badly on large arrays due to its work-inefficiency. We would like to find an algorithm that would approach the efficiency of the sequential algorithm, while still taking advantage of ...
The scan operation is a simple and powerful parallel primitive with a broad range of applications. In this chapter we have explained an efficient implementation of scan using CUDA, which achieves a significant speedup compared to a sequential implementation on a fast CPU, and compared to a ...
,K},gm∈CnBS×1,m∈M={1,2,…,M} is the channel matrix for the m-th BS-PU link, which is Convexity analysis The optimization problem consists of a SR maximization with respect to all SUs in the CRN, constrained by power limit at BS, PBS, and a maximum interference to any PU ...
At runtime, Fat-Free automatically generates an HTTP 404 error whenever it sees that an incoming HTTP request does not match any of the routes defined in your application. However, there are instances when you need to trigger it yourself....
For example, to maximize the downlink sum rate for a UAV-aided NOMA system, the joint placement, beam pattern and power optimization were carried out.21 Compared with the conventional NOMA, the transmit/receive beamforming with large phased arrays for millimeter-Wave (mmWave) NOMA system was ...
Sum of Pairs Given a list of integers and a single sum value, return the first two values (parse from the left please) in order of appearance that add up to form the sum. If there are two or mo...
As part of query optimization, every query is analyzed and, where appropriate, may be rewritten to use a summary table. Oracle8i's summary-rewrite capabilities are extremely powerful. Oracle8i manages definitions of dimensions and hierarchies, and uses this metadata to enable advanced query rewrites...
The time complexity of these algorithms for an 𝑟×𝑐r×c input is [𝑚𝑖𝑛(𝑟,𝑐)]2+𝑚𝑎𝑥(𝑟,𝑐)[min(r,c)]2+max(r,c). An application of these methods to optical and radio astronomy is given in [10]. Of course there are analogous problems for arrays of ...
