The cloud operating system （cloud OS） is used for managing the cloud resources such that they can be used effectively and efficiently. And also it is the duty of cloud OS to provide convenient interface for users and applications. However, these two goals are often conflicting because convenient abstraction usually needs more computing resources. Thus, the cloud OS has its own characteristics of resource management and task scheduling for supporting various kinds of cloud applications. The evolution of cloud OS is in fact driven by these two often conflicting goals and finding the right tradeoff between them makes each phase of the evolution happen. In this paper, we have investigated the ways of cloud OS evolution from three different aspects： enabling technology evolution, OS architecture evolution and cloud ecosystem evolution. We show that finding the appropriate APIs （application programming interfaces） is critical for the next phase of cloud OS evolution. Convenient interfaces need to be provided without scarifying efficiency when APIs are chosen. We present an API-driven cloud OS practice, showing the great capability of APIs for developing a better cloud OS and helping build and run the cloud ecosystem healthily.

Voluminous continental growth of the Altaids and its control on metallogeny

The Altaids is generally considered to be the largest Phanerozoic accretionary orogen on Earth,but it is unclear whether it was associated with extensive continental crustal growth and whether there is a link between the crustal growth and ore *** paper reviews whole-rock Nd and zircon Hf isotope data for felsic-intermediate-mafic igneous rocks in the Altaids and presents Nd+Hf isotopic contour maps for this *** maps highlight the 3D lithospheric compositional architecture of the Altaids and make it possible to quantitatively evaluate the crustal growth and its relationship with ore *** Altaids hosts ～4 107 350 km2and ～184 830 750 km3(assuming a crustal thickness of 40-50 km) juvenile crust(εNd(t)> 0),accounting for 58% by isotope-mapped area(～7 010 375 km2) of almost all outcrops of the Altaids(～8 745 000 km2) and formed during 1000-150 Ma(mainly 600-150 Ma).The juvenile crustal,slightly juvenile-reworked crustal and slightly reworked crustal provinces controlled the Cu-Au,the Pb-Zn-Ag and the Li-Be,Nb-Ta and W-Sn ore *** to the crustal architecture and background of deep compositions,we propose that the ore deposits can be grouped into three types:juvenile crust-related,mixed-source(or slightly juvenile crust)-related and reworked *** highlights the close relationship between accretion,continental growth and mineralization,and will facilitate exploration for specific ore-deposit types in the Altaids.
