PhD Positions in programming language runtimes (Python)
by David Bremner 02 May '18

02 May '18

1 Position I: Python on OMR =========================== The candidate will explore the benefits and challenges of using OMR [1] components (e.g. JIT, GC) in Python [2,3] runtimes. This may involve extending OMR in novel ways to better support Python, or vice-versa. If questions like how to balance fast startup time for scripting applications against good performance for compute-intensive workloads sound interesting, this might an opportunity for you. 2 Position II: Python and PGAS ============================== The candidate will implement support for parallel programming with Python, using the PGAS [4] (parallel global address space) model. The PGAS model can significantly simplify the implementation of parallel algorithms on distributed and shared memory computers. Challenges include enabling parallelism while dealing with Python's Global Interpreter Lock (GIL), and implementing distributed garbage collection efficiently. 3 Qualifications ================ Normally applicants to the Computer Science PhD program at UNB require a Master's degree in computer science or a closely related area. This project will require substantial hands-on and experimental work, and being comfortable with Python and C++. Familiarity with Linux and Open Source Software development would be a plus. For position I, exposure to programming language concepts like GC, JIT, and bytecode would be helpful. For position II, experience with parallel programming frameworks and/or languages such as MPI, OpenMP, X10 is an asset. 4 Environment ============= This project is supported by the IBM Centre for Advanced Studies (Atlantic) at the University of New Brunswick [5]. We have a lively group of students, postdocs, and research assistants working on related problems. Students work closely with both UNB researchers and technical experts from IBM, gaining valuable perspective and experience. 5 Support ========= These positions are "fully funded"; the exact funding package is subject to finalization but will be consistent with other fully funded students in Computer Science at UNB. You can find some information about expenses on the UNB web site [6]. 6 Contact ========= Send your resumé and unofficial transcripts by email to Stephen MacKay <smackay3(a)unb.ca> Please specify which position(s) you are interested in.

Fwd: [CfP][Meta'17] Workshop on Meta-Programming Techniques and Reflection
by William ML Leslie 29 Jun '17

29 Jun '17

---------- Forwarded message ---------- From: Stefan Marr <java(a)stefan-marr.de> Date: 29 June 2017 at 23:22 Subject: [CfP][Meta'17] Workshop on Meta-Programming Techniques and Reflection To: mlvm-dev(a)openjdk.java.net Call for Papers: Meta’17 ======================== Workshop on Meta-Programming Techniques and Reflection Co-located with SPLASH 2017 October 22, 2017, Vancouver, Canada Twitter @MetaAtSPLASH http://2017.splashcon.org/track/meta-2017 The heterogeneity of mobile computing, cloud applications, multicore architectures, and other systems leads to increasing complexity of software and requires new approaches to programming languages and software engineering tools. To manage the complexity, we require generic solutions that can be adapted to specific application domains or use cases, making metaprogramming an important topic of research once more. However, the challenges with metaprogramming are still manifold. They start with fundamental issues such as typing of reflective programs, continue with practical concerns such as performance and tooling, and reach into the empirical field to understand how metaprogramming is used and how it affects software maintainability. Thus, while industry accepted metaprogramming on a wide scale with Ruby, Scala, JavaScript and others, academia still needs to answer a wide range of questions to bring it to the same level of convenience, tooling, and programming styles to cope with the increasing complexity of software systems. This workshop aims to explore meta-level technologies that help tackling the heterogeneity, scalability and openness requirements of emerging computations platforms. ### Topics of Interest The workshop is a venue for all approaches that embrace metaprogramming: - from static to dynamic techniques - reflection, meta-level architectures, staging, open language runtimes applications to middleware, frameworks, and DSLs - optimization techniques to minimize runtime overhead - contract systems, or typing of reflective programs reflection and metaobject protocols to enable tooling - case studies and evaluation of such techniques, e.g., to build applications, language extensions, or tools - empirical evaluation of metaprogramming solutions - security in reflective systems and capability-based designs - meta-level architectures and reflective middleware for modern runtime platforms (e.g. IoT, cyber-physical systems, mobile/cloud/grid computing, etc) - surveys, conceptualization, and taxonomization of existing approaches In short, we invite contributions to the workshop on a wide range of topics related to design, implementation, and application of reflective APIs and meta-programming techniques, as well as empirical studies and typing for such systems and languages. ### Workshop Format and Submissions This workshop welcomes the presentation of new ideas and emerging problems as well as mature work as part of a mini-conference format. Furthermore, we plan interactive brainstorming and demonstration sessions between the formal presentations to enable an active exchange of ideas. The workshop papers will be published in the ACM DL, if not requested otherwise by the authors. Thus, they will be part of SPLASH workshop proceedings. Therefore, papers are to be submitted using the SIGPLAN acmart style: http://www.sigplan.org/Resources/Author/.

Exposing rpython based functions to cpython vm.
by Aleksandr Koshkin 19 Jun '17

19 Jun '17

Hello, folks) I have been tinkering with pypy source tree for a week now and came up with a following question - is there any way to build a rpython program as a shared object which exposes some of its functionality (say a list of functions) for standard cpython vm, in other words I want this functions to be invokable from python script via shared object import. When I try to build my program like so: python rpython --shared -O2 some_program.py libmyprogram-c.so actually gets generated, unimportable from cpython though. Should I use CFFI for cpython next or there is some sort of facility (decorator or something)? -- Kind regards, Aleksandr Koshkin.

Hi guys, The latest cppyy package doesn't seem to ship with cling 0.3 which supports both of those compilers. I can't find the repository for the package to attempt to contribute myself. Can you direct me to the repository or upgrade to the latest cling? Best Regards, Omer Katz.
