Intel® Advanced Vector Extensions

Intel Software Conference 2014

 A Intel Software Brasil realizou neste mês o Intel Software Conference 2014, que aconteceu na Universidade Estácio de Sá (Rio de Janeiro) nos dias 26 e 27 de Maio e no IMAM (São Paulo) nos dias 28,29 e 30 de Maio.

Foram realizadas palestras e "round tables" ministradas por profissionais da Intel do Brasil, Estados Unidos e Alemanha cobrindo dois temas: Computação Paralela e de Alto Desempenho nos primeiros quatro dias (RJ e SP) e Desenvolvimento Android no último dia (somente em São Paulo).  

Confira logo abaixo os slides das apresentações realizadas.

  • Broken links for MPX GCC version on the Intel server?

    I'm not sure where else to post issues with downloads so I'm just posting it here. At the following URL I'm trying to download the patched version of GCC. The download, however, stops before it is finished. I have tried to download these files from different physical systems, using e.g. Firefox and wget; just to exclude issues on my side. Is there any more recent static version of GCC with MPX available?

    AVX _mm256_store_ps


    I am wanting to run the following code using the AVX instruction set,

     I compile without any problem but generates an error when I run:


    "Segmentation fault (core dumped)"

    Reviewing the code the problem is in the instruction: 

      _mm256_store_ps(&total,acc); //Error

    Could someone point me to to be.

    Thank you


    I compile with the following command: 

    gcc -O3 vec_avx.c -mavx -o vec_avx.x

    And the main code is as follows:

    Intel MPX, unable to reproduce results in example

    In trying to reproduce the example given by Ady Tal at I encounter the following problem:

    Terminal 1:

    $ ../sde-external-6.22.0-2014-03-06-lin/sde64 -mpx-mode -debug -- ./mpx_test3
    Application stopped until continued from debugger.
    Start GDB, then issue this command at the (gdb) prompt:
      target remote :44736

    Terminal 2:

    Submissions open: High Performance Parallelism Gems

    We have all had our little discoveries and triumphs in identifying new and innovative approaches that increased the performance of our applications. Occasionally we find something more, something that could also help others, an innovative gem. You now have an opportunity to broadcast your successes more widely to the benefit of our community. You are invited to submit a proposal to a contribution-based book, working title, “High Performance Parallelism Gems – Successful Approaches for Multicore and Many-core Programming” that will focus on practical techniques for Intel® Xeon® processor and Intel® Xeon Phi™ coprocessor parallel computing. Submissions are due by May 29, 2014.

    SIGILL on AVX instruction


    I have a very simple test program that I'm using to play around with AVX instruction sets. It works perfectly fine on my MacBook Pro, however, the same piece of code will fire off a SIGILL on my Linux workstation. I check cpuid before invoking the instructions and /proc/cpuinfo is also has the AVX flag set. I'm using clang with the -mavx command line switch. The instructions throwing the exception are any _mm256_xxx ones. I'm not using the FMA instructions. /proc/cpuinfo says I have 12 cores of Intel(R) Xeon(R) CPU E5-1660 0 @ 3.30GHz.



    help with 1073741819

    hi, i don't know it i am posting on the correct position of forum (i'm not an expert), anyway 

    i'm using a proprietary software that give me an error on an executable file, the error say this: "aborted with system error code 1073741819".

    the assistance of this software say me that is a bug that comes up when i execute it on intel 4th generation processor

    they say also that the  workaround is to rename the file mkl_avx2.dll to this: mkl_avx2.dll. 

    but for me it doesn't work, maybe because i'm using an 3th generation processor (i7 3610QM) 


    Intel® graphics virtualization update

    Traditional business models, built on graphics and visualization usages such as workstation remoting, VDI, DaaS, transcoding, media streaming, and on-line gaming, are beginning to draw open source attention, worldwide. Employees are becoming mobile. They want flexibility of working from any device, anywhere, anytime, with any data, without any compromise in the quality due to access, latency or visualization.
