Intel® Fortran Studio XE

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.

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. 

The file size is twice bigger when writing real8 into binary file.

Hi,

I am a newbie to Fortran language. I try to write a real8 array into binary file using code as follow (compiler: Intel Fortran 2015)

open(unit=219, status='replace',file='data.bin',form='unformatted')
do j=1,ny2dval
do i=1,nx2dval
   write(219) fzavg(i,j)
end do
end do

 

But the file size is twice bigger than expected. It seems to write a real16 array. Why does it happen? Any suggestions?

 

Thanks a lot!

repeat initialization of local variable

I found a forum topic similar to this, from 2009.  Notwithstanding the Fortran standard: ""A variable, or part of a variable, shall not be explicitly initialized more than once in a program", there is a method to the following madness.

This legacy program defined an array for which the "default" value was 0, and some elements were then assigned non-zero values.  A trivial example:

integer a(2,2,2)
data a/8*0/
data a(2,2,2)/1/

initialization of local variables

My co-developer reports that, contrary to his expectations, Intel Fortran seems to be initializing local numeric variables, both scalar and array, to 0 or 0.0

I should note that In our application, all local variables are saved, and all arrays are pre-allocated (sizes are explicit in the code).  No arrays or structures are allocated at run-time, and no local variables are recursive.

Is his generalization correct?

runtime problems with PSBLAS library

Hello,

About two years ago I reported ifort F03 compilation issues with  PSBLAS library (http://people.uniroma2.it/salvatore.filippone/psblas/). With Intel 2015, the compilation issues are solved but there are runtime problems. I have also tried the Ifort 2016 Beta and same problem occurs. PSBLAS is usable with several other compilers (such as GNU/IBM/CRAY) other than Intel. We are thoroughly using Intel Compilers for research and using PSBLAS will save us big time for not reinventing the wheel.
