I have two questions about WRITE/READ operations on shared arrays.
1) In my program I write a different element of a given shared array at every iteration of an OpenMP-parallelized DO LOOP. The results that I get should be right but I'm just wondering whether this is fine or I should enclose the READ/WRITE section in a CRITICAL block. Then, I also READ elements from a shared array without modifying them and it seems to work. Are these procedures correct?
If you thought the invention of the World Wide Web resulted in massive business and societal change, you haven’t seen anything yet! The Internet of Things has been described as the evolution of the Internet, and it has the potential to drastically transform lives and industries.
Until now, only humans were able to connect to the Internet. The new era of connectivity sees everyday objects equipped with network connectivity, allowing them to send and receive data without any human interaction.
