+## About
+
+The LLVM Developers' Meeting is a bi-annual gathering of the entire LLVM Project community. The conference is organized by the LLVM Foundation and many volunteers within the LLVM community. Developers and users of LLVM, Clang, and related subprojects will enjoy attending interesting talks, impromptu discussions, and networking with the many members of our community. Whether you are a new to the LLVM project or a long time member, there is something for each attendee.

+To see the agenda, speakers, and register, please visit the Event Site here: https://llvm.org/devmtg/2016-03/#schedule
+
+What can you can expect at an LLVM Developers' Meeting?
+
+- **Presentations**
+
+  A concise overview of the topics being presented. 
+
+
+- **Tutorials**
+
+  Tutorials are 60 minute sessions that dive down deep into a technical topic. Expect in depth examples and explanations.
+
+
+- **Lightning Talks**
+
+  These are fast 5 minute talks that give you a taste of a project or topic. Attendees will hear a wide range of topics and probably leave wanting to learn more.

+- title: LLVM Foundation
+  speaker: LLVM Foundation board of directors

+  description: "This BoF will give the EuroLLVM attendees a chance to talk with some of the
+    board members of the LLVM Foundation. We will discuss the Code of Conduct and
+    Apache2 license proposal and answer any questions about the LLVM Foundation."

+- title: Compilers in Education
+  speaker: Roel Jordans (Eindhoven University of Technology), Henk Corporaal (Eindhoven University of Technology)
+  slides_url: https://llvm.org/devmtg/2016-03/BoF-Minutes/CompilersInEducation.pdf
+  description: "While computer architecture and hardware optimization is generally well covered
+    in education, compilers are still often a poorly represented subject. Classical
+    compiler lecture series seem to mostly cover the front-end parts of the
+    compiler but usually lack an in-depth discussion of newer optimization and code
+    generation techniques. Important aspects such as auto-vectorization, complex
+    instruction support for DSP architectures, and instruction scheduling for
+    highly parallel for VLIW architectures are often touched only lightly. However,
+    creating new processor designs requires a properly optimizing compiler in order
+    for it to be usable by your customers. As such, there is a good market for
+    well-trained compiler engineers which does not match with the classical style
+    of teaching compilers in education."

+- title: Surviving Downstream
+  speaker: Paul Robinson (Sony Computer Entertainment America)

+  description: 'We presented "Living Downstream Without Drowning" as a tutorial/BOF
+    session at the US LLVM meeting in October. After the session, Paul
+    had people coming to talk to him for most of the evening social event
+    and half of the next day (and so missed several other talks!).
+    Clearly a lot of people are in this situation and there are many
+    good ideas to share.'

+- title: Polly - Loop Optimization Infrastructure

+  slides_url: https://llvm.org/devmtg/2016-03/BoF-Minutes/PollyLoopOptimizationInfrastructure.pdf
+  description: "The Polly Loop Optimization infrastructure has seen active development
+    throughout 2015 with contributions from a larger group of developers located at
+    various places around the globe. With three successful Polly sessions at the US
+    developers meeting and larger interest at the recent HiPEAC conference in Prag,
+    we expect various Polly developers to be able to attend EuroLLVM. To facilitate
+    in-persona collaboration between the core developers and to reach out to the
+    wider loop optimization community, we propose a BoF session on Polly and the
+    LLVM loop optimization infrastructure. Current hot topics are the
+    usability of Polly in an '-O3' compiler pass sequence, profile driven
+    optimizations as well as the definition of future development milestones.
+    The Polly developers community will present ideas on these topics, but
+    very much invites input from interested attendees."

+  speaker: David Chisnall (Computer Laboratory, University of Cambridge)
+  slides_url: https://llvm.org/devmtg/2016-03/BoF-Minutes/HowToMakeLLVMMoreFriendly.pdf
+  description: "LLVM has always had the goal of a library-oriented design. This implicitly
+    assumes that the libraries that are parts of LLVM can be used by consumers that
+    are not part of the LLVM umbrella. In this BoF, we will discuss how well LLVM
+    has achieved this objective and what it could do better. Do you use LLVM in an
+    external project? Do you track trunk, or move between releases? What has
+    worked well for you, what has caused problems? Come along and share your
+    experiences."

+  video_url: ""
+  description: "LLVM is a large, complex piece of software with many interlocking components. Testing a system of this magnitude is an arduous task. Random testing is an increasingly popular technique used to test complex systems. A successful example of this is Csmith, a tool which generates random, semantically valid C programs. We present a generic method to generate random but structured intermediate representation code. Our method is implemented in LLVM to generate random Machine IR code for testing the post-instruction selection stages of code generation."

+  description: "Although the importance OpenMP as a parallel programming model and its adoption in Clang/LLVM is increasing, existing data-race checkers have high overheads and generate many false positives. We propose ARCHER, a data race checker that achieves high accuracy and low overheads on large OpenMP applications. Built on top of LLVM/Clang and TSan, it uses scalable happens-before tracking and modular interfaces with OpenMP runtimes. ARCHER significantly outperforms TSan and Intel Inspector XE. It helped detect critical data races in the Hypre library."

In this allocator, a program's control structure is represented as a tree of tiles, and a two-phase algorithm colors the tiles based on both local and global information.
