[jimdempseyatthecove · Accepted solution]

Prior to using the compiler you must setup (select) the environment.

Depending on what you want, this will be something like:

source /opt/intel/2019/bin/ifortvars.sh intel64

There is a similar souce command for including mpi

Please read the documentation about setting up the build environment.

https://software.intel.com/en-us/articles/setting-up-the-build-environment-for-using-intel-c-or-fortran-compilers

Sorry about the above link being old, Look in your current documentation (Or google)"

or

Dear Jim Dempsey,

Thank you very much for your detailed and helpful guidance.! I followed the link mentioned by you and this one is updated in April 2019, so I resolved my issue and now I can make my code with ifort. Just as a side comment, since I did not install rest of the features of Intel parallel studio apart from Intel Fortran and Vtune amplifier so in future is there a probability that my calculation may get influence due to other uninstalled compilers and libraries? Further, you mentioned about mpi, do I also need to source mpi to use ifort efficiently?

With kind regards,

Qais

[jimdempseyatthecove]

When your application does not use MPI then you do not need to source the mpi shell script.

Is there a reason why you did not install all of the packages from Intel?

You should be ok with what you installed for building and running Fortran applications as long as you do not include some of the extended libraries. For example MKL, MPI, etc...

Jim Dempsey

[ali__qais]

Dear Dempsey,

I guess for the time being I do not need MPI, but I will use it in future subject to requirement.

Reasons for not installing all packages are partially related to space availability but mainly my program only requires Intel fortran for now so I preferred custom installation. However, during installation, I once tried to install all packages to the directory where I have around 400 GB  free space but still I was getting error of space limitations.

Best,

Qais

[Ron_Green]

So besides the target directory, the compiler has to extract the RPMs in temp space, default is /tmp.  What does 'df -k' show for that, if it's in a separate partition or something perhaps it is constrained.  You can export TMPDIR to a location with more space perhaps.

[ali__qais]

Dear all,

I am using ifort to run a fortran based code which runs Monte Carlo simulations. I can run code successfully for some of  the calculations but for others I am facing dimension error, what could be the possible reasons, can it be related to array allocation or size of my pc memory? How may I resolve this issue? Your suggestions are highly acknowledged. 

Best regards,

Qais

[Juergen_R_R]

First of all, this is a different issue, so please open up another thread. Questions you should answer are: 1. which Monte Carlo simulation / which code, 2. compilation error or runtime error, 3. what is the exact error message, 4. please show some code.

[jimdempseyatthecove]

>>can it be related to array allocation or size of my pc memory?

Possibly (we haven't seen your code)

If you are defining a parameter to specify the size of your array .AND. the array is statically allocated:

REAL :: ARRAY(YourBigParameterNumberHere)

Then depending on where ARRAY is located (module, COMMON or local to the procedure), it will either be a static array or a stack allocated array. In the case of a static array, you may have a linker limitation of 2GB, if on the stack then you may have a stack limitation.

To work around this, it is suggested that  you make the array ALLOCATABLE

REAL, ALLOCATABLE :: ARRAY(:)
...
! Somewhere early in your program
ALLOCATE( ARRAY(YourBigParameterNumberHere))

Dear all,

Many thanks for your continuous support. I have been using ifort version 19.0.3.199 20190206.  Now, I would like to use 2020 version of ifort, but I am unable to find a (easy and quick) way of doing it. Can anyone please share a helpful link in this regard or a method to follow? Thanks in advance!

Best,

Ali 

[Devorah_H_Intel]

There is no 2020 version of ifort. The latest version of the Intel Fortran Compiler is 19.1 that is available as part of Parallel Studio XE 2020

Please see this article for additional information https://software.intel.com/en-us/articles/intel-compiler-and-composer-update-version-numbers-to-compiler-version-number-mapping

[ali__qais]

Thanks Devorah, I updated ifort to 19.1 version and it helped in my work. 

[ali__qais]

Dear all,

I have recently tried to install intel parallel_studio_xe_2020.0.088 on my computer system and started to source to set-up the environment as given below;

~/intel_ifort/parallel_studio_xe_2020.0.088/compilers_and_libraries_2020/linux/bin> source compilervars.sh
but I am facing following error.

PROD_DIR=/home/ali/intel_ifort/compilers_and_libraries_2020.0.166/linux: Command not found.
INTEL_TARGET_ARCH=: Command not found.
INTEL_TARGET_PLATFORM=linux: Command not found.
INTEL_HOST_PLATFORM=Linux: Command not found.
COMPILERVARS_ARGV=0: Command not found.
COMPILERVARS_ARGV: Undefined variable.

Your kind suggestions to resolve this issue are greatfully acknowledged.  

Cheers,

Hello,

I have a question : how I can integrate Intel Parallel Studio 2020 to Mirosoft Visual Studio ?

I installed Microsoft Visual Studio 2019 in first and after that, I installed Intel Patallel Studio 2019, but when I launch Microsoft Visual Studio to write a Fortran code, I don't find intel(R) Visual Fortran.

Best,

[jimdempseyatthecove]

The normal procedure is:

Start a shell (this usually places you in your home directory)
cd to your project folder
from your project folder source the intel compiler variables. something like:

    source /opt/intel_ifort/parallel_studio_xe_2020.0.088/compilers_and_libraries_2020/linux/bin/compilervars.sh intel64

IOW specify the path to the installation folder (which may differ from that I wrote above) together with the shell script file and followed by the argument intel64 .OR. ia32

See: https://software.intel.com/en-us/articles/setting-up-the-build-environment-for-using-intel-c-or-fortran-compilers

Jim Dempsey

[ali__qais]

Dear Jim,

Thanks for your kind response. I used to use ""source compilervars.sh -arch intel64 -platform linux" before, which worked well for me. This time I installed intel on another computer system of mine and did the same, just like you also suggested (please see below)

~/intel_ifort/parallel_studio_xe_2020.0.088/compilers_and_libraries_2020/linux/bin> source compilervars.sh -arch intel64 -platform linux  

However, the problem remains same.

PROD_DIR=/home/ali/intel_ifort/compilers_and_libraries_2020.0.166/linux: Command not found.
INTEL_TARGET_ARCH=: Command not found.
INTEL_TARGET_PLATFORM=linux: Command not found.
INTEL_HOST_PLATFORM=Linux: Command not found.
COMPILERVARS_ARGV=4: Command not found.
COMPILERVARS_ARGV: Undefined variable.

 I wonder if it has to deal with some other stuff apart from source issue.

Best wishes,

Qais

You appear to be not using the correct commands. it took 20 seconds of searching to find the correct commands - see above. 

In this world you need to follow the fm. 

Jim appears to have it correct 

Enter source compilervars.sh ia32|intel64 or source compilervars.csh ia32|intel64

this does not mean source ......

Enter source is English for enter everything after the word source not including source - it is an idiom:

Command prompt>compilervars.sh ia32|intel64

pick either 32 or 64 versions. 

Good hunting.  

[WHeat__Had]

Hello,

How I can integrate Intel Parallel Studio to Microsoft Visual Studio ? (I need to compile a Fortran code)

Thanks

[Steve_Lionel]

The article is terrible and I have asked Intel to fix it. When it says "ia32|intel64" it doesn't mean that literally - it is trying to say pick one or the other. Also the article doesn't make it clear that you have to include the path to the script in the "source" command.

[jimdempseyatthecove]

In Linux there is the concept of current directory. When you launch a Terminal Window, you typically start in your login's home directory. Usually indicated by ~. The Terminal Window prompt on my system looks like:

[jim@KNL ~]$

Note, your prompt may look like:

[YourUserNameHere@YourSystemNameHere ~]$

From here you usually use cd to change your directory to that of your development:

[jim@KNL ~]$cd workspace/foobar

[jim@KNL foobar]$

At this point you "source" the compilervars

[jim@KNL foobar]$source /opt/intel_ifort/parallel_studio_xe_2020.0.088/compilers_and_libraries_2020/linux/bin/compilervars.sh intel64

You only type in what follows the $

In the above, I elected to specify the 64-bit build environment

*** This environment is set (active) until you exit the shell (terminal)

Note 2: If you (incorrectly) run the compilervars.sh directly (i.e. as opposed to via source), the shell script will pop off the IVF environment variable settings. Using the command "source" preserves the settings that are set in the shell script compilervars.sh.

You will get familiar with this behavior as you use the system.
