Big Data requires processing huge amounts of data. Intel Advanced Vector Extensions 2 (aka AVX2) promoted most Intel AVX 128-bits integer SIMD instruction sets to 256-bits. Intel AVX brought 256-bits floating-point SIMD instructions, but it didn't include 256-bits integer SIMD instructions. Intel AVX2 allows you to operate with the AVX 256-bits wide YMM register for integer data types. In this post, I’ll explain how developers can speedup big data processing with the new 256-bits integer SIMD instructions.
The code is compiled using MSVC2010 SP1, with /arch:AVX, and the AVX version is slightly (5~10%) slower than the SSE version. I am using an E-1230 V2 processor with 16GB dual-channel DDR3-1600 memory.
Intel® Math Kernel Library includes powerful and versatile random number generators that have been optimized to take full advantage of Intel® Advanced Vector Extensions 2 (aka Intel® AVX2) introduced with the Haswell CPUs.
I am using the SDE emulator with AVX2 instruction set, I have written some simple program but it is crashing in RELEASE mode with SDE emulator.
Please let me know whether SDE emulates the stack related operations or not. YASM synatxed assembly programming

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.
I'm not sure where else to post issues with downloads so I'm just posting it here. At the following URL https://software.intel.com/en-us/articles/intel-software-development-emu... 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?
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:
Could someone point me to to be.
I compile with the following command:
gcc -O3 vec_avx.c -mavx -o vec_avx.x
And the main code is as follows:
In trying to reproduce the example given by Ady Tal at https://software.intel.com/en-us/articles/debugging-applications-with-in... I encounter the following problem:
$ ../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:
