Native Directly Follows Operator [article]

Alifah Syamsiyah, Boudewijn F. van Dongen, Remco M. Dijkman
2018 arXiv   pre-print
We define a native operator for the simplest form of the intermediate structure, called the "directly follows relation".  ...  Therefore, in this paper, we propose a native SQL operator for direct process discovery on relational databases.  ...  Native Directly Follows Operator In this section, we introduce a new native directly follows operator for computing directly follows relation.  ...

Jdib: Java Applications Interface to Unshackle the Communication Capabilities of InfiniBand Networks

Wan Huang, Hongwei Zhang, Jin He, Jizhong Han, Lisheng Zhang
2007 2007 IFIP International Conference on Network and Parallel Computing Workshops (NPC 2007)  
In this paper, we propose Jdib (Java Direct InfiniBand), a Java application acceleration technique to directly exploit RDMA (Remote-Direct-Memory-Access) capability of In-finiBand network hardware.  ...  Thus, JVM can perform native I/O operations directly upon direct byte buffers, avoiding the copy of buffer's content using an intermediate buffer whenever an invocation of one of the underlying operating  ...  system's native I/O operations is done.  ...

Creating Java to Native Code Interfaces with Janet

Marian Bubak, Dawid Kurzyniec, Piotr Łuszczek, Vaidy Sunderam
2001 Scientific Programming  
The Java Native Interface (JNI) API is portable but too inconvenient to be used directly owing to its low-level API.  ...  This paper presents Janet — a highly expressive Java language extension and preprocessing tool that enables convenient integration of native code with Java programs.  ...  Janet simplifies these operations by allowing Java syntax to be embedded directly inside the C code.  ...

AVMM: Virtualize network client with a bare-metal and asymmetric partitioning approach

Yuezhi Zhou, Yaoxue Zhang, Hao Liu, Naixue Xiong
2011 2011 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)  
By letting user OS possess the most part of resources and access some peripheral devices directly, the AVMM overhead is reduced greatly, improving the whole network system performance.  ...  This paper presents the design, implementation, and evaluation of AVMM, a symmetric partition-based bare-metal client virtualization approach that tries to achieve maximum near-native performance for end-users  ...  It is noted that the DMA device is not virtualized and accessed directly to improve the operation performance.  ...

On the effectiveness of API-level access control using bytecode rewriting in Android

Hao Hao, Vicky Singh, Wenliang Du
2013 Proceedings of the 8th ACM SIGSAC symposium on Information, computer and communications security - ASIA CCS '13  
We have provided a systematic evaluation to assess the effectiveness of API-level access control using bytecode rewriting on Android Operating System.  ...  More specifically, we have the following questions: (1) Can applications directly talk to kernel? (2) Can applications directly invoke native libraries?  ...  The following code snippet from android_runtime library demonstrates this technique: § INVOKE NATIVE METHOD DIRECTLY From the discussions above, it is clear that to access privileged resources at the  ...

Application Layer Multicast extensions to RELOAD

Mario Kolberg, John Buford
2011 2011 IEEE Consumer Communications and Networking Conference (CCNC)  
Native multicast deployment is relatively slow and linked with a number of issues. However, there are a number of native multicast regions.  ...  Application Layer Multicast (ALM) can be used in areas of the network where there is no native multicast available.  ...  In addition to these overlay level tree operations, some peers may implement additional operations to map tree operations to native multicast and/or AMT connections.  ...

2015 Distributed and parallel databases  
The major innovation is that a CloudMdsQL query can exploit the full power of local data stores, by simply allowing some local data store native queries (e.g. a breadth-first search query against a graph  ...  CloudMdsQL is a functional SQL-like language, capable of querying multiple heterogeneous data stores (relational and NoSQL) within a single query that may contain embedded invocations to each data store's native  ...  can be generated directly within the code of the native expression friendships.  ...
