Apache Hive

Compare

Claimed by Apache Software Foundation Analyzed 17 days ago

Hive is a data warehouse infrastructure built on top of Hadoop that provides tools to enable easy data summarization, adhoc querying and analysis of large datasets data stored in Hadoop files. It provides a mechanism to put structure on this data and it also provides a simple query language called ... [More] Hive QL which is based on SQL and which enables users familiar with SQL to query this data. At the same time, this language also allows traditional map/reduce programmers to be able to plug in their custom mappers and reducers to do more sophisticated analysis which may not be supported by the built-in capabilities of the language.

Vecmathlib

Compare

  Analyzed 15 days ago

Vecmathlib provides efficient, accurate, tunable, and most importantly vectorizable math functions such as sqrt, sin, or atan. The library is implemented in C++, and intended to be called on SIMD vectors, e.g. those provided by SSE, AVX, or available in Power7 and Blue Gene architectures. The ... [More] same algorithms should also work efficiently on accelerators such as GPUs. Even without vectorization, vecmathlib's algorithms are efficient on standard CPUs. [Less]

GeantV

Compare

  Analyzed about 2 years ago

Detector simulation is one of the most CPU intensive tasks in modern High Energy Physics. While its importance for the design of the detector and the estimation of the efficiency is ever increasing, the amount of events that can be simulated is often constrained by the available computing ... [More] resources. Various kind of "fast simulations" have been developed to alleviate this problem, however, while successful, these are mostly "ad hoc" solutions which do not replace completely the need for detailed simulations. One of the common features of both detailed and fast simulation is the inability of the codes to exploit fully the parallelism which is increasingly offered by the new generations of CPUs. [Less]
