Lightweight Virtualized Containers for Network Function Virtualization (NFV)

This article breaks down container management systems, and describes how they interact with virtual machines in systems such as Intel Clear Containers and the upcoming Kata Containers project. It also explains how NFV support is built into these systems via the virtcontainers library.

  • SGXKernel: A Library Operating System Optimized for Intel® SGX

    In this paper, we revisit the library OS porting approach in a new setting---Intel SGX. We first quantitatively evaluate the performance impact of enclave transitions on SGX programs, identifying it as a performance bottleneck for any library OSes that aim to support system-intensive SGX applications. We then present the design and implementation of SGXKernel, an in-enclave library OS, with highlight on its switchless design, which obviates the needs for enclave transitions.The results show that SGXKernel significantly outperforms a state-of-the-art library OS that has been ported to SGX.

  • Merging MPI Intercommunicators

    Sometimes you may have completely separate instances for an MPI job.  You can connect these separate instances using techniques such as MPI_Comm_accept/MPI_Comm_connect, which creates an intercommunicator.  But in more complex situations, you may have a significant number of separate intercommunicators, and want to send data between arbitrary ranks, or perform collective operations across all ranks, or other functions which are most efficiently handled over a single intracommunicator.

  • Troubleshooting Visual Studio Command Prompt Integration Issue

    Issue Description

    Nmake and ifort are not recognized from a command window, however using Intel Fortran under Visual Studio works perfectly.

    Troubleshooting

    Follow below checklist to troubleshooting Visual Studio command environmental issues:

    1. Verify whether ifort and nmake are installed correctly:

        For Visual Studio 2017, nmake is installed at:

        C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64\nmake.exe
