问题 I have installed intel mkl library. contents have path /home/user/intel/..... . I have to run a C++ code using make file on which it is mentioned. CC = /home/user/intel/bin/icpc -g INCLUDE = -I/home/user/intel/mkl/include LIB = -L/home/user/intel/mkl/lib/intel64 -lmkl_core -lmkl_intel_lp64 -lmkl_intel_thread -liomp5 -lpthread -std=c++11 I have successfully installed parallel_studio_xe_2019_update5_cluster_edition . but still I'm getting an error message that ./main :error while loading shared

Strange linking error with intel mkl using gcc under ubuntu

一曲冷凌霜 提交于 2020-01-24 19:46:12
问题 I want to use intel mkl in some optimazation problems, so I use intel example to test it. test.cpp: #include <mkl.h> #include <stdio.h> typedef struct { double re; double im; } complex16; extern "C" void cblas_zdotc_sub(int, const void*, int, const void*, int, void*); #define N 5 int main() { int n, inca = 1, incb = 1, i; complex16 a[N], b[N], c; n = N; for(i = 0; i < n; i++) { a[i].re = (double)i; a[i].im = (double)i * 2.0; b[i].re = (double)(n - i); b[i].im = (double)i * 2.0; } cblas_zdotc

Calling multithreaded MKL in from openmp parallel region

有些话、适合烂在心里 提交于 2020-01-20 05:21:33
问题 I have a code with following structure #pragma omp parallel { #omp for nowait { // first for loop } #omp for nowait { // first for loop } #pragma barrier <-- #pragma omp single/critical/atomic --> not sure dgemm_(....) #pragma omp for { // yet another for loop } } For dgemm_, I link with multithreaded mkl. I want mkl to use all available 8 threads. What is the best way to do so? 回答1: This is a case of nested parallelism. It is supported by MKL, but it only works if your executable is built

Numpy-MKL for OS X

好久不见. 提交于 2020-01-12 19:05:24
问题 I love being able to use Christoph Gohlke's numpy-MKL version of NumPy linked to Intel's Math Kernel Library on Windows. However, I have been unable to find a similar version for OS X, preferably NumPy 1.7 linked for Python 3.3 on Mountain Lion. Does anyone know where this might be obtained? EDIT: So after a bit of hunting I found this link to evaluate Intel's Composer XE2013 studios for C++ and Fortran (both of which contain the MKL), as well as a tutorial on building NumPy and SciPy with it

Fix arithmetic error in distributed version

五迷三道 提交于 2020-01-11 10:47:27
问题 I am inverting a matrix via a Cholesky factorization, in a distributed environment, as it was discussed here. My code works fine, but in order to test that my distributed project produces correct results, I had to compare it with the serial version. The results are not exactly the same! For example, the last five cells of the result matrix are: serial gives: -250207683.634793 -1353198687.861288 2816966067.598196 -144344843844.616425 323890119928.788757 distributed gives: -250207683.634692

No speed-up after using MKL for Eigen

倖福魔咒の 提交于 2020-01-06 15:43:10
问题 I use Eigen 3.3 and Intel MKL 2017, and write and run program in Visual Studio 2012 with Win-7 64-bit system and Intel Xeon(R) CPU E5-1620 v2@3.70GHZ CPU. I belive that my configuration for MKL is correct, because I can succesfully run MKL examlpe codes. The configuraton for using Intel MKL from Eigen follows from https://eigen.tuxfamily.org/dox/TopicUsingIntelMKL.html. For Visiual Studio 2012, I complie codes via Intel C++ Complier in Release x64 model. However, the following code always

Does the EPD Free distribution use MKL?

你离开我真会死。 提交于 2020-01-05 07:38:22
问题 According to the Enthought website, the EPD Python distribution uses MKL for numpy and scipy. Does EPD Free also use MKL? If not does it use another library for BLAS/LAPACK? I am using EPD Free 7.3-2 Also, what library does the windows binary installer for numpy that can be found on scipy.org use? 回答1: The EPD Free 7.3 installers do not include MKL. The BLAS/LAPACK libraries which they use are ATLAS on Linux & Windows and Accelerate on OSX. 回答2: According to this table, EPD Free 7.3 does not

Increase stack size of main program or create a new thread with larger stack size for recursive code blocks?

问题 I've a following up question to What is the stack size of a BackgroundWorker DoWork Thread? Is there way to change it? Should I increase the stack size of my main program using the following post build event: "$(DevEnvDir)..\..\VC\bin\editbin.exe" /STACK:8388608 "$(TargetPath)" or should I capsule my recursive code block inside a new thread with a larger stack size? Thread thread = new Thread(delegate() { // do work with larger stack size }, 8192 * 1024); thread.Start(); thread.Join(); The

How to install CVXOPT with Enthought python (Canopy)

a 夏天 提交于 2020-01-01 12:06:27
问题 Before I start, let me put alternative titles for this post: How to compile CVXOPT with Intel MKL ? How to change __init__.py in CVXOPT to compile with Intel MKL ? Let me explain the issue. I am trying to install pystruct with Enthought python because Enthought python provides significant speed up in comparison to python in the Ubuntu package manager. The speed-up are mostly due to compiling back-end linear algebra libraries with Intel MKL libraries. I have to say that CVXOPT and pystruc
