This is the third Annual Concurrency Forum meeting of a series on meetings held at Fermilab in 2011 and 2013 to explore the possibility that interested High Energy Physics (HEP) institutions and projects collaborate on concurrent frameworks and applications R&D. The main goal of the Concurrency Forum is to communicate and exchange information and results. The goals for the April 2014 annual meeting are the following:

• Discuss progress made with each demonstrator, drawing conclusions for those that have completed their work programme and identifying topics that still need to be investigated.
• Experiments/proejcts could report on its current views on parallelism issues, such as choice of concurrency model and software technologies. This will be an opportunity for us all to discuss and see if we can converge on a common overall strategy.
• Possibility of launching development projects with specific deliverables that can be of benefit to the whole community.
