Hello everyone. I am new to multi threading programming. Recently, i have a project, which i apply cilk_for into it. Here is the code:
the following simple code seems to run just fine, however, cilkscreen is shouting "Race condition"!
Shall I trust it? Or it is just false sharing?
So, what scalable memory allocator is fast and thread safe to use with intel cilk plus?
GCC* 4.9 was released on April 22, 2014. This release now supports Version 4.0 of the OpenMP* specification for the C and C++ compilers. The interface between the compilers and the GCC OpenMP runtime library (libgomp) was changed as part of this development. As a result, code compiled by GCC 4.9 using the –fopenmp compiler option cannot be successfully linked with the Intel® OpenMP runtime library (libiomp5), even if it uses no new OpenMP 4.0 features.

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>" : error : 010101_239
1> compilation aborted for General\CilkTest.cpp (code 4)
========== Build: 0 succeeded, 1 failed, 3 up-to-date, 0 skipped ==========
Is there any efficient prefix scan library for Cilk Plus accessible from C?
I was not able to find any and my implementation can hardly compete with the sequential version :-)
An interface similar to the reducers will work nicely.
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.
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 ?
