Dear sir,

I got a following error message when I run intel Fortran in my linux machine.

Error: A license for Comp-FL could not be obtained

ifort: error #10052: could not checkout FLEXlm license

So I found the topic. And the answer is to get a new lisence.

But I couldn't find the menu to get a student license.

How can I get a student license?

And How can I replace the license file from my machine?

please help me.

With Centos 7 (and RHEL 7) system services on restart of the computer are now controlled by systemd.  When I installed the Intel Flexlm license server software it does not seem to create a service there or provide a script (as the README implies) as a sample of getting the license server to auto restart after a reboot of the system.  The documentation that I read on the Intel web pages seems to suggest that lmgrd can be restarted interactively, but I would like it to auto restart.  Is there a way to do this or a sample init script for /etc/systemd/system/multi-user.target.wants/ ????

The Intel Parallel Studio XE 2018 (IPSXE2018) Update 2 has been released together with the Intel compiler 18.0.2. This version of Intel compiler provides the fix for Spectre variant 2. Please refer to this article for more information -  https://software.intel.com/en-us/articles/using-intel-compilers-to-mitigate-speculative-execution-side-channel-issues.

We will keep you posted when any additional fixes will be available.

Hello,

I stumbled upon some strange behavior today.

program power_test

	implicit none
	
	print *, 5.d0 * 3.d0 ** 2
	print *, 3.d0 ** 2 * 5.d0
	print *, 5.d0 * 3.d0 ** -2
	print *, 3.d0 ** -2 * 5.d0

end program power_test

ifort -m64 -fpp -fopenmp -O3 -g -traceback -C -c power_test.f90
ifort power_test.o -m64 -fpp -fopenmp -O3 -g -traceback -C -o power_test.x		

gives

   45.0000000000000     
  45.0000000000000     
  0.555555555555556     
  1.693508780843029E-005

So, when the exponent is positive, everything works as expected, but when it is negative, the multiplication is evaluated first, and then the power, but only if the multiplication comes after the power. Is this intended and if yes why?

Dear All,

I am facing a problem with a code that is related to the status of a pointer after a call to the BLAS subroutine zcopy.

The very simple code is the following:

program test
integer, parameter :: n = 10, m = 21 ! if m=11 the code works
real(8) :: A(n,m)
real(8), pointer :: C(:,:)
! initialize A
A = 0.0
A(1,2) = 4.5
allocate(C(1:m,1:n))
C = transpose(A)
! the call to zcopy should reassign A to its transpose.
call zcopy(n*m, C,1,A,1)
! deallocation here is not succesful
deallocate(C)
end program test

The compiler 17.04 fails to deallocate C, complaining that it is not allocated. If I change m from 21 to 11, the programs doesn't fail and the deallocation is succesful. I have a linux system with Ubuntu 16.04. 

Could anyone help me to understand what rules am I breaking about the status of pointers?

Thanks

Raffaele

Dear,

I wrote a Coarray Fortran program for solving sparse linear systems of equations using Preconditioned Conjugate Gradient algorithm. I tested it on 2 datasets on a HPC with SLURM as scheduler. For compilation, I used Intel fortran 17.0.0. Sparse matrix-vector multiplications are done with MKL subroutines.

For one dataset, the Coarray Fortran program always gave the correct answer, when all the images were on the same node or when each image was on a different node (i.e., 1 image per node).

For a second dataset, the same Coarray Fortran program gave the correct answer when all the images were on the same node.

ISSUE: However, when there was 1 image per node, the program diverged and gave wrong answers!

I compiled the same program with the options "-g -check all -traceback" and tested the debug version on the second dataset with 1 image per node. The debug version gave the correct answer, even with 1 image per node!

So, I am lost and cannot find the reason the program goes wrong with a specific dataset and a specific configuration (1 image per node). Using debug options did not help because no warning/error messages were written! Any hints, please?

The code sources can be found on github:

ttps://github.com/jvdp1/pcgcoarray

The dataset could be provided on request.

In advance thank you for the help.

Yours sincerely,

Jeremie

i want to know the the commands to set up environment in ubuntu 16.04 and 14.04 using intel ifort in bash file.

i am using Intel® Parallel Studio XE Cluster Edition for Linux* 2018 update 2.

with little knowledge and information that i could install it but getting export command nor found. its probably due to environment issues.

the documentation didnt help me

Hi, we purchased Intel Cluster Studio XE for Linux in 2014, still have the serial number and the original install file (l_ics_2013.1.046.tgz), with the license in /opt/intel/licenses. We will be doing an OS upgrade and bare metal install, and are wondering if we can still just run install.sh again, and copy the license file as such -- is there any other procedure we need to follow? I ask because for some reason the software is not shown under the licenses under my login (either as updates, hidden, etc.) ... and am wondering if this indicates some problem that should be addressed before the upgrade.

sir

i have intel parallel_studio_xe_2018_update1_cluster_edition installed in my laptop having ubuntu 16.04 OS.  i need to work with fortran compiler.

I am not sure if i am giving correct path to set up environment.  i have given in .bashrc file

export PATH
LD_LIBRARY_PATH="/opt/intel/2018/compilers_and_libraries_2018.1.163/linux/compiler/lib/intel64:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH

2 in same .bashrc file if i mention

/opt/intel/2018/compilers_and_libraries_2018.1.163/linux/bin/ifortvars.sh intel64

i get this message if i open a terminal.....

Hello,

I am trying to install FVCOM in ubuntu with ifort version 18. after setup the libraries, I try to compile the module and when i type make in the terminal this error showed up.

Lorri, Steve,

Greetings from LANL!

I have a code dominated by 3 intrinsics:   TRANSPOSE, MAXVAL, and NORM2.  the arguments are large arrays/vectors.  I have 36 or more cores at our disposal. 

First, am I correct in assuming these are potentially vectorized but not threaded by default?

I am considering writing my own replacements for these with nested loops and applying appropriate OMP PARALLEL and OMP SIMD directives.  However it would be nice to find threaded versions of these.  In MKL maybe?

Thanks

Ron

I am using derived-type array in fortran. I ran the executable through valgrind and realized that I am leaking memory. After poking around, I realized that the leaking is related to a compiler flag '-qopenmp'. If this flag is used with intel15, valgrind detects memory leak.

Here is the relevant part of valgrind report when I use intel15 with '-qopenmp' flag:

I am attaching a simple code that mimics this error. To compile the code, please run the compile.sh script.

Hi everyone,

We have some legacy code in F77, and there are many math function, like matrix and/or vector multiplication, copy vectors, initialization of vector and matrix. All of these F77 code are optimized (like unrolling). 

From the optimization report, I can see these functions are inlined and operations are all VECTORIZED (estimated potential speedup about: 1.6). 

However, if I replace these F77 function call by F90 code, 

for example (a matrix multiply a vector here)

c(:) = matmul(a(:,:),b(:)). 

I can save about 50% time for these matrix and vector operation. 

Does this mean I still have overhead even these functions are inlined?

Could anyone give me some explanationand suggestion about how to optimize these code? Thank you in advance!

What's the difference between buying the Intel fortran cluster version versus buying a professional version and then downloading the free IMPI library? 

We have a server that compiles some code just fine. I am trying a help someone out in compiling the same code on a 2nd server that we just brought up. I am his system administrator and I am trying to install the necessary packages to compile and link this software. We are using the same Intel compiler on both systems xe_2017-update 1. Here is the error we get when trying to link:

I am not a programmer, just trying to osrt this out. Thank you.

I started writing fortran in 1959, ie, right at the beginning.  I just tried writing a program to read in a big file, and ran into trouble.  The file is 31,215 numbers, and is in blocks of 200 with, it seems, an EOF at the end of each block.  My program balks at that.  I need to get all 31,215 numbers. How do I get past the EOF?
