Intel® C++ Compiler

Compilation of the same code under Win and Linux with Intel Compiler

Hello,

I'm not sure if this is the proper forum to post on, so please excuse me if my question should have been posted elsewhere.

We are developing software that depends heavily on numerical computation and we want to use intel compiler to achieve a boost in our performance. So far, the platform we have been developing on is Linux.

We consider purchasing Intel® Parallel Studio XE 2015 Composer Edition for Linux and Windows.

crashes

I have been operating an open source chess program tournament for a long time, and I have noticed that some contestants compiled with the Intel compiler crash and result in the engine losing the game as well as spawning an error message in Windows

I have Visual Studio and I have tried new project and loaded one of the problem engines and after cleaning up some defects related to the C++ ISO standard I was able to make a stable x64 build

now the program works fine, so this tells me the Intel compiler needs some work on it to eliminate the crashing

 

 

I'm getting symbol _cilk_spawn could not be resolved when compiling with icpc

Hi,

Im using Ubuntu 14.04 & eclipse & intel compiler v 15

I have 2 same cilk programs (one with as c program and the other as cpp program).

I can compile it with icc (without any problem) 

But when I'm using icpc (cpp program) I'm getting errors: symbol _cilk_spawn could not be resolved 

In those same 2 programs Im not using any flags.

What is the different with cpp program, which I cant compile

Feature request: improve error messages: Option cannot change across modules: 0

2>  Option cannot change across modules: 0
2>xilink: : error #10014: problem during multi-file optimization compilation (code 1)
2>xilink: : error #10014: problem during multi-file optimization compilation (code 1)

This error message is not meaningful, nor useful.

The problem is when I link statically *.lib that was compiled with offload constructs set to "None" and *.exe was compiled with "Optional".

xilink.exe crashes and MSVS reports error code -1073740777

I was trying to offload some computation to GFX, and process "xilink.exe" crashes and output in visual studio says:

2>xilink: : error #10014: problem during multi-file optimization compilation (code -1073740777)
2>xilink: : error #10014: problem during multi-file optimization compilation (code -1073740777)

I thought we are in 21st century, so cryptic error codes were so popular in early 90's...

tqli hangs on i7-4790

Hello,

i am using the routine tqli from the book Numerical Recipes (www.physics.sdsu.edu/~johnson/phys580/tqli.c) since several years without any problems on different processors and different compilers. I have a new computer with i7-4790K.

Now this routine hangs somtimes. With same input values sometime it works and sometimes it hangs in an infinite loop.(the while lopp nerver ends)

The code is compiled with intel c++ compiler v14 but it also happens with the newest v15.
