New challenges to file systems' metadata performance are imposed by the continuously
growing number of files existing in file systems. The total amount of metadata can become …

With the growth of online services, a large amount of files have been generated by users or
by the service itself. To make it easier to service users with different network environments …

With the convergence of high-performance computing (HPC), big data and artificial
intelligence (AI), the HPC community is pushing for “triple use” systems to expedite scientific …

随着物联网向各行业的深入发展, 各行业的信息化进程也进入了快车道. 信息服务作为物联网在
各行业应用中重要的公共服务之一, 一直受到广泛关注. 然而, 当前物联网信息服务系统面对物 …

With the rapid development of the Internet of Things (IoT), the IoT is characterized by a wide
variety of data sources, large scale and heterogeneous structure. But those characteristics …

As large file systems increasingly grow in size, metadata operations become one of the
major performance bottlenecks that constrain the overall I/O performance. Previous analysis …

Exponentially growing capacities of disk drives have increased the problem that not only a
complete disk can fail, but also individual, small groups of sectors can be erroneous. These …

In this paper, aiming at realizing directive-based temporal blocking for out-of-core stencil
computation, we present an extension of OpenACC directives and a source-to-source …

File systems as well as I/O libraries offer interfaces which can be used to interact with them,
albeit on different levels of abstraction. While an interface's syntax simply describes the …

While an input/output (I/O) interface's syntax describes the available operations, its
semantics determines how these operations behave and which assumptions developers …
