    Qihoo360 Atlas

    Qihoo360 Atlas

    A high-performance and stable proxy for MySQL

    Atlas is a MySQL protocol-based database middleware project developed and maintained by the infrastructure team of the Web platform Department in QIHU 360 SOFTWARE CO. LIMITED(NYSE:QIHU). It fixed lots of bugs and added lot of new functions on the basis of MySQL-Proxy 0.8.2. Currently, the project has been widely applied in QIHU, many MySQL businesses has connected to the Atlas platform. The number of read and write requests forwarded by Atlas has reached billions. Rewrite all lua code with C, Lua is only used for the management interface. Rewrite the network model and the threading model. Optimize the locking mechanism, performance improved immensely. When Atlas start, it will create multiple threads. One of them is the main thread, the others are working threads. The main thread is responsible for monitoring the connecting requests from clients, and the working thread only monitor the command request from the main thread.

    MsQuic

    MsQuic

    Cross-platform, C implementation of the IETF QUIC protocol

    MsQuic is a Microsoft implementation of the IETF QUIC protocol. It is cross-platform, written in C and designed to be a general-purpose QUIC library. MsQuic also has C++ API wrapper classes and exposes interop layers for both Rust and C#. QUIC has many benefits when compared to existing "TLS over TCP" scenarios. MsQuic has several features that differentiate it from other QUIC implementations. Optimized for client and server. Optimized for maximal throughput and minimal latency. Asynchronous IO. Receive side scaling (RSS) support. UDP send and receive coalescing support. All packets are encrypted and handshake is authenticated with TLS 1.3. Parallel streams of (reliable and unreliable) application data. Exchange application data in the first round trip (0-RTT). Improved congestion control and loss recovery. Survives a change in the clients IP address or port. Stateless load balancing.

    Distributed Multithread Apriori (DMTA)

    A parallel implementation using MPI and OpenMP to Apriori algorithm

    DMTA (Distributed Multithreaded Apriori) is a parallel implementation of Apriori algorithm, which exploits the parallelism at the level of threads and processes, seeking to perform load balancing among the cores. Was implemented in C++ language, using the parallelization libraries OpenMP and MPI. The algorithm was generated as a result of a project developed by André Camilo Bolina, under the guidance of teachers Marluce Rodrigues Pereira, Ahmed Ali Abdalla Esmin and Denilson Alves Pereira, in Department of Computer Science at Federal University of Lavras. The results of this project were published in the Revista de Sistemas de Informação da FSMA and is available in http://www.fsma.edu.br/si/edicao11/FSMA_SI_2013_1_Principal_1.html
