Composer XE Fortran Intel®

Webinar May 13 - What's New in Intel Fortran 16.0

Wed, May 13, 2015 12:00 PM - 1:00 PM EDT

This session will cover new features in the Intel® Fortran compiler version 16, part of Intel® Parallel Studio XE 2016. Topics include new features from Fortran standards, new OpenMP* features and changes for users of Microsoft Visual Studio*.

This session will be recorded and the recording made available sometime afterward.

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?

First Derivative

Hi,

I have some data (z,h) which reprents sinusoidal curve. Now, I would like to calculate first derivative dh/dz at each point (z,h).

I am using Intel Fortran Compiler with IMSL.

Can you please help me in this regard?

Cheers

Doctor Fortran in "The Future of Fortran"

In November 2014, I led a session at SC14 (the event formerly known as “Supercomputing”) titled “The Future of Fortran”. I invited representatives from other vendors and members of the Fortran standards committee to participate, and had some accept, but when it came time for the session, I was up there alone. Oh well…

Multiple versions of fortran and MS visual studio

Hi,

I'm writing some fortran subroutines and linking them to a commercial code. The code is in the form of a library, and it was compiled with intel fortran  parallel studio XE 2013, with MS Visual Studio 2010.

I set up MS Visual Studio 2013 (with the added SDK) and I got an evaluation version of Intel Parallel Studio XE 2015 Composer Edition for Fortran Windows.  I got that to install and compiled the fortran files, and when I try to link everything up into an executable (using a makefile and MS incremental linker version 12.00.21005.1) ) I get the following:

ICE in select type with class(*)

The code below produces an internal compiler error, if the /debug:full option is enabled.

program main
  implicit none

    real :: foo(2,2)
    foo = 1.0

    call testSub(foo)

  contains

  subroutine testSub(matrix)
    class(*), intent(inout) :: matrix(:,:)  ! << This works
!    class(*), intent(inout) :: matrix(2,2)  ! << This fails
    select type(local => matrix)
      type is (real)
    end select
  end subroutine testSub

end program

Problem with an unresolved symbol _for__rtc_uninit_src

Hello,

for one of our program suites I keep getting a bizarre link error, which my colleagues do not experience. The message is:

error LNK2001: unresolved external symbol _for__rtc_uninit_use_src   

By the looks of it and from checking the sources (we do not have a routine of that name) I guess that this is a routine that should be in the runtime libraries. So, my question is: how can I solve this?

For your information:

Is this is bug? Error: Invalid signal or error

Program Test
    implicit none
  INTEGER, PARAMETER :: dble = SELECTED_REAL_KIND(P=10,R=50)
  INTEGER, PARAMETER :: sngl = SELECTED_REAL_KIND(P=5)
  REAL (KIND = dble), ALLOCATABLE, DIMENSION(:), TARGET  ::  wk3 , wk10,rsb0
  REAL (KIND = dble), DIMENSION(:), POINTER :: cpmu,rhocp,rsn
   INTEGER  err
   INTEGER  mswk10,mswk3,mst,ncomp,mstart
   integer m221,mrrb,msn,m
    REAL (KIND=dble)::result11

Random reading of an unformatted file?

Hi All,

I have a large file of geographic information created thus:

open(1,file=trim(shapefile),status='replace',form='unformatted',iostat=ios, &
   err=1000,recl=128,recordtype='stream')

I read the whole file and display its information on screen. The user clicks somewhere on screen and from that I know I have to re-sample a small part of the file starting at some byte N. Is there some Fortran way I can get at that byte number immediately without having to start from the beginning of the file?

Many thanks

Mike
