Arquitectura Intel® para muchos núcleos integrados

High-Performance, Modern Code Optimizations for Computational Fluid Dynamics

Modern server farms consist of a large number of heterogeneous, energy-efficient, and very high-performance computing nodes connected with each other through a high-bandwidth network interconnect.  Such systems pose one of the biggest challenges for engineers and scientists today:  how to solve complex, real-world problems by efficiently using the enormous computational horsepower available from the vast number of multi-core arrays comprising these systems.

  • OpenCL on Xeon Phi: no accelerators detected

     

    Hi all,

    I got stuck on making opencl work with Xeon Phi. Tried google, but not very useful. Maybe it is a trivial question, but I am very new to Xeon Phi. Please give me some hints. :)

    I download a sample code from this tutorial https://software.intel.com/en-us/articles/using-the-intel-sdk-for-opencl-applications-xe-2013 and try to compile and run it. The compilation was fine. Problem is when I try to run it, I got an error

    New to OpenMP on MIC: Master/Workers thread configuration

    Hi all,

    I'm new to OpenMP. I'm trying to implement a program that runs on a Xeon Phi card. The program consists of a master thread and worker threads. 
    The workers maintain hash tables, one each, and the master sends commands to the workers to insert new elements, find elements and delete elements.
    I've looked through some documentation but there's an abundance of constructs and I got a bit lost.
    I thought I'd be able to do something like this:

    Xeon Phi single thread performance and Scaling.

    Hi,

    We are trying to improve performance of our climate modeling application on Xeon Phi (offload mode), but not able to achieve desired speed-up. So, we picked up a small section of code from the application we are working on, and created a standalone version out of it to check the performance for Xeon vs Xeon Phi as well as scaling efficiency on both the machines. The code is fully vectorized, and we are using O2 optimization level on the intel fortran compiler.

    Cannot start MPI job from host system [me too, but SOLVED]

    Hi, 

    I wasn't sure whether or not to add a new post since I seem to have exactly the same problem as what's explained here: https://software.intel.com/en-us/forums/intel-many-integrated-core/topic... , but I didn't solve the problem.

    I am running RHEL6.5, OFED 3.18.1 with 4 Xeon Phi cards in a external static bridge. The IP addresses are:
    Host: 192.168.1.16
    mic0: 192.168.1.17
    mic1: 192.168.1.18
    mic2: 192.168.1.19
    mic3: 192.168.1.20
