Internal compiler error 010101_239

Hi guys,

I condensed our project down to a piece of code that lets you reproduce the following issue.
When I compile this in Release configuration (Debug works), I get this compiler error:

1>------ Build started: Project: ng-gtest, Configuration: Release x64 ------
1> CilkTest.cpp
1>" : error : 010101_239

1> compilation aborted for General\CilkTest.cpp (code 4)

Cilk worker scheduling

Hello,

I would like to understand better how Cilk scheduling works. 
I am not sure how to phrase this question so I give it my best.

I have downloaded the latest Intel Cilk runtime release (cilkplus-rtl-003365 -  released 3-May-2013).
I use the classical Fibonacci example in Cilk.

Parallel Search With Cilk Plus

Hi everyone , I have a program that generating random number if it does not exist in ( allocated custom size) array  then add array. But if custom size is very big   ( 1 million )  after a period search is very slowing down. I did learn  cilk_for and reducers.I want to paralleize but I could not decide what reducer is suitable for array. Is there someone who can help me ? 

(Sorry for my english if you do not understand my problem you can write my e-mail   " 03011241@st.meliksah.edu.tr " )  

 

Question on the Status of Cilk Plus Support in GCC Mainline

Hi,

I read from the GCC 4.9.0 release notes that http://gcc.gnu.org/gcc-4.9/changes.html

Support for Cilk Plus has been added and can be enabled with the -fcilkplus option. Cilk Plus is an extension to the C and C++ languages to support data and task parallelism. The present implementation follows ABI version 1.2; all features but _Cilk_for have been implemented.

Cilk view got error with program compiled by GCC 4.9.0

Hi,

Recently, I have been compiling my Cilk plus program with GCC 4.9.0. Then I ran Cilk view to measure its parallelism and got this error:

Cilkview: Generating scalability data

Cilkview Scalability Analyzer V2.0.0, Build 3229

C:Tool (or Pin) caused signal 11 at PC 0x7f9124cd1dd3

 

Interestingly, when I compiled the program with GCC 4.8.2 and ran it with Cilk view again, it ran fine. So does it only happen with GCC 4.9.0? My guess is that GCC 4.9.0 isn't stable enough or not compatible with Cilk view at this time.

Thanks, 

Question on reducers

In my search application there are globally variables defined outside any function that I would like to use the cilk reducers on.

Specifically I have code like this:

#include "search.h"

static int total_users = 0;
static int total_matches = 0;

These total_x variables are incremented throughout the application on different functions.

I tried adding the following for total_users and received the following error:
