Intel® C++ Compiler

32-bit libraries not found

As I was installing Intel Parallel Studio Linux C++.  It says:

32-bit libraries not found
32-bit libraries not found on this system.
This product release requires the presence of 32-bit compatibility libraries when running on Intel(R) 64 architecture systems. One or more of these libraries could not be found:
libstdc++ (including libstdc++6)
glibc
libgcc
Without these libraries, the compiler and the debugger will not function properly. Please refer to Release Notes for more information.

Imperfect Loop Unroll-Jammed by 2 (pre-vector)

Hi, I am optimizing an application. I am facing the below warning message in xxx.optrpt file.

(I gave -qopt-report=5 option.)

      remark #25461: Imperfect Loop Unroll-Jammed by 2   (pre-vector)

What would be the general requirements of perfect loop unroll-jamming?

I don't see any kinds of explanations about this warning in icc reference manual.

Also, what is the meaning of (pre-vector)? 

I am using icc 15.0.2 and unfortunately, I cannot upload the code here because it is very complex and large code.

 

 

icc 15.0.3 cannot compile std::vector<double> constructor with headers from gcc 5.1.1

The following simple program doesn't compile with icc 15.0.3 on Fedora 22.  It does work on Fedora 20.  I think the main difference is that Fedora 22 is using gcc 5.1.1, which is where the header files come from.  In contrast Fedora 20 uses gcc 4.8.3.

 

I don't know how to interpret the error message.

stringstream bug

Hi,

In my program writing in C++, I use a few functions that use stringstream classes.

I do not have any problems with compilation of  my program by Visual Studio 2013 and Intel Parallel Studio 2013.

The same program I tried using  Visual Studio 2015 and Intel Parallel Studio 2015 XE Update 4.

I do not have any problems with compilation of  my program by MS compiler but when try to use Intel C++ compiler I get only one error:

1>": : error : ** The compiler has encountered an unexpected problem.

Missing links from psxevars.sh to composer_xe - Parallel Studio 2015 update 3

Hey,

I've installed the latest version of the Intel Parallel Studio XE -Cluster-Edition- 2015 Update 3 and found a minor bug:
After installation I've tried to source the psxevars.sh which worked for all features (Vtune, Amplifier, etc,) except the Intel compilers and MPI-Variables.

The reason: psxevars.sh tries to load the compilervars.sh. (see attached extract of source code)
