Slides from May 4th Webinar on Cilk

Hi all,

We did a webinar this morning at 8am Pacific time on changes and new updates in Cilk in the Intel Parallel Composer beta. I am posting the slides here. Let me know if there's any interest to do another webinar on this around 5pm or so Pacific time - I want to see if there's anyone that couldn't attend due to the time that would have liked to attend. Thanks everyone, and I really enjoyed the questions in today's session.

pipe screen output to file

i am fairly new to fortran and am using an existing code it opens a file using

 OPEN (6,FILE='outdata')

it is my understand that 6 is reserved for printing to screen and so this works to direct anything printed to screen to the outdata file and it works when i use gfortran for example 

but when i use ifort it does not is there any simple way for me to fix this with out going through the entire code and changing every print statement (there are many of them)

Trying to Update to 2016 version

I have Intel Parallel Studio 2015 XE Composer Edition for Fortran Windows installed and downloaded the 2016 version and it takes forever to come to the welcome screen and then tells me it can't install and has the warning below:


 Intel® Visual Fortran Compiler will not work because none of the supported environments is found on your computer

Call Fortran from C


I am trying to learn how to call Fortran from C, I am able to create .so file from C and call it from Ruby On Rails,

the C code is:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

long add(long maxn, double delta, double conf, char *errMsg)
        long ERR_MSG_LENGTH, answer;
        unsigned i;
        char * iarr;

       iarr = "Hello!";

        answer = (long) (maxn+delta+conf);

Call Fortran from C


Hi, I have many codes in Fortran and I wrapped it by C to create .dylib in Mac and I can call it from Ruby On Rails. 

Recently we have lots of trouble with Mac Server and we want to transfer everything to Linux, but the Fortran code

will not compile in Linux, the error message is !!DEC$ ATTRIBUTES DLLEXPORT, C :: addsize is not supported

in this platform. Is there a way to get around this without having to rewrite Fortran codes using  ISO_C_BINDING?
