We conduct an experimental study to investigate the causal impact of social identity on individuals' performance under incentives. We focus on China's household registration (hukou) system, which favors urban residents and discriminates against rural residents in resource allocation. Our results show that making individuals' hukou identity salient(More)
Providing high-speed data transfer is vital to various data-intensive applications. While there have been remarkable technology advances to provide ultra-high-speed network bandwidth, existing protocols and applications may not be able to fully utilize the bare-metal bandwidth due to their inefficient design. We identify the same problem remains in the(More)
Data-intensive applications place stringent requirements on the performance of both back-end storage systems and front-end network interfaces. However, for ultra high-speed data transfer, for example, at 100 Gbps and higher, the effects of multiple bottlenecks along a full end-to-end path, have not been resolved efficiently. In this paper, we describe our(More)
Providing high-speed data transfer is vital to various data-intensive applications supported by data center networks. We design a middleware layer of high-speed communication based on Remote Direct Memory Access (RDMA) that serves as the common substrate to accelerate various data transfer tools, such as FTP, HTTP, file copy, sync and remote file I/O. This(More)
Data-intensive applications frequently rely on multicore computer systems, in which Non-Uniform Memory Access (NUMA) is a dominant architecture. To transfer data into and out from these high-performance computers becomes a bottleneck, and thus it is crucial to understand their I/O performance characteristics. However, the complexity in NUMA architecture(More)
Providing high-speed data transfer is vital to various data-intensive applications in cloud computing systems. We design a middleware layer of high-speed communication based on Remote Direct Memory Access (RDMA) that serves as the common substrate to accelerate various data transfer applications in cloud computing, such as FTP, HTTP, file copy, sync and(More)
Polydimethylsiloxane (PDMS) and SU-8 are currently two very commonly used polymeric materials in the microfluidics field for biological applications. However, there is a pressing need to find a simple, reliable, irreversible bonding method between these two materials for their combined use in innovative integrated microsystems. In this paper, we attempt to(More)
