We explore the possibility of exploiting the computing power of chip-multiprocessor-based network interface controllers and switches in a system area network environment. We use stream processing applications as case studies to show that combining the compute-power of the host processor and a CMP-based NIC with 4 CPU cores can achieve speedup up to 1.30 even with the NIC running at one tenth th...

We empirically evaluate interrupt-related covert channels, in short IRCCs, a type of covert channel that leverages hardware interrupts for communication. The evaluation is based on an exploit of IRCCs that we implemented as a proof-of-concept. We use a combination of experimental evaluation and information-theoretic analysis to compute the bandwidth of the channel on a concrete system. Our anal...

Today’s modern high-end Network Interface Cards (NICs) are equipped with an onboard CPU. In most cases, these CPU’s are only used by the vendor and are operated by a proprietary OS, which makes them inaccessible to the HPC application developer. In this paper we present a design and implementation of a framework for building high-performance networking applications. The framework consists of an...

The local aromaticity of a series of benzenoid systems was determined through the use of structurally (HOMA) and magnetically (NICS) based measures, and also by using a new electronically based indicator of aromaticity, the para-delocalization index (PDI). The results were compared with the predictions of Clar’s aromatic -sextet rule. It is found that, for all analyzed benzenoid hydrocarbons ha...

We investigate the similarity of the country endowments of the newly industrialized East Asian countries (NICs) and their major developed trading partners since the 1960s. In particular, we analyze their factor endowments in the years 1965, 1977, and 1990, using the lens condition of Deardorff (1994). Because of the similarity of endowments of the NICs and their developed-country trading partne...

Regional Analysis a Members of the WHO Western Pacific Region Global Influenza Surveillance and Response System are provided in the Acknowledgements. S easonal influenza is an acute viral infection that causes annual epidemics. The World Health Organization (WHO) estimates that the global disease burden of seasonal influenza is approximately one billion cases annually resulting in up to 500 000...
