Difference on creating a CUDA context for timing a kernel (warmups)

Measuring the execution time of a CUDA kernel can become a bit tricky, especially when the computation time is short.

10th IEEE International Symposium on Parallel and Distributed Processing with Applications

I have been this week in The 10th IEEE International Symposium on Parallel and Distributed Processing with Applications, where I’ve contributed with a paper entitled “Efficient GPU asynchronous implementation of a watershed algorithm based on cellular automata”.

Qt Creator + CUDA + Linux – Review

As many people has found my last (and only) post interesting, I’ve decided make an update taking into account the problems that people had when they followed the instructions. I’ve also improved the .pro file with new tricks I’ve found in the last year.

Qt Creator + CUDA + Linux

This post has a review in this other post
Qt Creator + CUDA + Linux – Review.

I’ve been googling for a while looking for info about Qt Creator and CUDA and there is not too much information about this topic, at least useful. The topic ‘QMake build script for CUDA‘ in the nvidia forum pointed me the way. Basically we need to tell our qt project file how to generate the Makefile to include the CUDA stuff. A basic .pro file to run the HelloQtCuda World program looks like this:

Machine::reset()

Sooner or later everybody’s blog goes R.I.P. Sometimes a reset is done and old post are lost. The orange machine’s blog was a place for the topics related to the master and sometimes… people read it! (praise to wordpress and google search engines) , so i’ll keep the old one just in case. So, this is a reset/new creation blog about CUDA  for some reasons.-
