Fix for 2015 Update 4 Composer Edition install exiting

Some users may experience a problem where installing Intel Parallel Studio XE 2015 Composer Edition for Fortran Windows Update 4 exits the installer after clicking Next on the first install screen. This is most likely to occur if the system also has Intel VTune Amplifier XE or Intel Advisor XE installed.

The problem will be fixed in Update 5. A workaround is as follows:

Free Intel Visual Fortran for students!

Intel Fortran is now available under a free, non-commercial license for qualified students on Linux, OS X and WIndows. See https://software.intel.com/en-us/qualify-for-free-software/student for more details.

Note: If you don't already have a supported Microsoft Visuall Studio installed, you'll need to get one first as the student license doesn't include the VS Shell-based IDE. The free Visual Studio 2013 Community Edition will do.

OS X 10.9 Xcode 5 error ld: library not found for -lcrt1.10.6.o

Environment:  OS X 10.9 (Mavericks) and Xcode 5.0

Command line compilations/links fail with "ld: library not found for -lcrt1.10.6.o"

Affected compiler:  Intel Composer XE 2013 Update 1

Root cause:  Xcode 5.0 installation does not install all command line tools (include files, libraries, SDKs) need for the compiler to link user applications. 

Оптимизировали, оптимизировали, да не выоптимизировали!

Оптимизация? Конечно, каждый сталкивался с данной задачей при разработке своих, сколь-нибудь значительных, требующих определённых вычислений, приложений. При этом способов оптимизировать код существует огромное множество, и, как следствие, различных путей сделать это в автоматическом режиме с помощью опций компилятора. Вот здесь и возникает проблема – как выбрать то, что нужно нам и не запутаться?

Bug in Intel MPI Fortran compiler version 15

Dear All,

There appears to be an obscure bug in version 15 of the Fortran compiler involving MPI, OpenMP and string passing all together.

We're running on Intel hardware under Linux. First the compiler:

mpif90 --version

ifort (IFORT) 15.0.3 20150407
Copyright (C) 1985-2015 Intel Corporation.  All rights reserved.

... now the smallest code I could devise which still has the bug:

Installing PETSc with Intel MPI and compilers

Hi,

I need to install and build PETSc with Intel MPI and compilers. It has so far been unsuccessful.

It seems that I need to know which mpi libraries to link to

The compiling and building is done in cygwin64.

The commands are:

export PETSC_DIR=`pwd`

export PETSC_ARCH=petsc-3.6.0_win64_impi_vs2012_debug

I then tried the 4 options below but they all failed. Does anyone manage to get it working?
