Investigating the Feasibility of an MPI-Like Library Implemented in .Net Using Only Fully Managed Code
Investigating the Feasibility of an MPI-like Library Implemented in .Net Using Only Fully Managed Code Daniel Holmes MSc in High Performance Computing The University of Edinburgh Year of Presentation: 2007 Abstract The .Net development platform and the C# language, in particular, offer many benefits to programmers including increased productivity, security, reliability and robustness, as well as standards-based application portability and cross-language inter-operation. The Message Passing Interface (MPI) is a standardised high performance computing paradigm with efficient, frequently-used implementations in many popular languages. A partial implementation of McMPI, the first MPI-like library to be targeted at .Net and written in pure C#, is presented. It is sufficiently complete to demonstrate typical application code and to evaluate relative performance. Although the effective bandwidth for large messages (over 100 Kbytes) using 100Mbit/s Ethernet is good, the overheads introduced by .Net remoting and object serialisation are shown to result in high latency and to limit bandwidth to 166Mbit/s when using a 1Gbit/s Ethernet interconnection. A possible resolution that still uses pure C#, i.e. using .Net sockets, is proposed but not implemented. Contents Chapter 1.

The Zonnon Project: a .NET Language and Compiler Experiment
The Zonnon Project: A .NET Language and Compiler Experiment Jürg Gutknecht Vladimir Romanov Eugene Zueff Swiss Fed Inst of Technology Moscow State University Swiss Fed Inst of Technology (ETH) Computer Science Department (ETH) Zürich, Switzerland Moscow, Russia Zürich, Switzerland [email protected] [email protected] [email protected] ABSTRACT Zonnon is a new programming language that combines the style and the virtues of the Pascal family with a number of novel programming concepts and constructs. It covers a wide range of programming models from algorithms and data structures to interoperating active objects in a distributed system. In contrast to popular object-oriented languages, Zonnon propagates a symmetric compositional inheritance model. In this paper, we first give a brief overview of the language and then focus on the implementation of the compiler and builder on top of .NET, with a particular emphasis on the use of the MS Common Compiler Infrastructure (CCI). The Zonnon compiler is an interesting showcase for the .NET interoperability platform because it implements a non-trivial but still “natural” mapping from the language’s intrinsic object model to the underlying CLR. Keywords Oberon, Zonnon, Compiler, Common Compiler Infrastructure (CCI), Integration. 1. INTRODUCTION: THE BRIEF CCI and b) to experiment with evolutionary language HISTORY OF THE PROJECT concepts. The notion of active object was taken from the Active Oberon language [Gut01]. In addition, two This is a technical paper presenting and describing new concurrency mechanisms have been added: an the current state of the Zonnon project. Zonnon is an accompanying communication mechanism based on evolution of the Pascal, Modula, Oberon language syntax-oriented protocols , borrowed from the Active line [Wir88]. -

INTRODUCTION TO .NET FRAMEWORK NET Framework .NET Framework is a complete environment that allows developers to develop, run, and deploy the following applications: Console applications Windows Forms applications Windows Presentation Foundation (WPF) applications Web applications (ASP.NET applications) Web services Windows services Service-oriented applications using Windows Communication Foundation (WCF) Workflow-enabled applications using Windows Workflow Foundation (WF) .NET Framework also enables a developer to create sharable components to be used in distributed computing architecture. NET Framework supports the object-oriented programming model for multiple languages, such as Visual Basic, Visual C#, and Visual C++. NET Framework supports multiple programming languages in a manner that allows language interoperability. This implies that each language can use the code written in some other language. The main components of .NET Framework? The following are the key components of .NET Framework: .NET Framework Class Library Common Language Runtime Dynamic Language Runtimes (DLR) Application Domains Runtime Host Common Type System Metadata and Self-Describing Components Cross-Language Interoperability .NET Framework Security Profiling Side-by-Side Execution Microsoft Intermediate Language (MSIL) The .NET Framework is shipped with compilers of all .NET programming languages to develop programs. Each .NET compiler produces an intermediate code after compiling the source code. 1 The intermediate code is common for all languages and is understandable only to .NET environment. This intermediate code is known as MSIL. IL Intermediate Language is also known as MSIL (Microsoft Intermediate Language) or CIL (Common Intermediate Language). All .NET source code is compiled to IL. IL is then converted to machine code at the point where the software is installed, or at run-time by a Just-In-Time (JIT) compiler. -

It has been discussed by many independent persons as long ago as 1954. It might not be difficult to prove that “this was well-known to Babbage,” so no effort has been made to give credit to the originator, if indeed there was a unique originator. 4 “Everybody knows that UNCOL was a failure” • Subsequent attempts: – Janus (1978) • Pascal, Algol68 – Amsterdam Compiler Kit (1983) • Modula-2, C, Fortran, Pascal, Basic, Occam – Pcode -> Ucode -> HPcode (1977-?) • FORTRAN, Ada, Pascal, COBOL, C++ – Ten15 -> TenDRA -> ANDF (1987-1996) • Ada, C, C++, Fortran – .... 5 Sharing parts of compiler pipelines is common • Compiling to textual assembly language • Retargetable code-generation libraries – VPO, MLRISC • Compiling via C – Cedar, Fortran, Modula 2, Ada, Scheme, Standard ML, Haskell, Prolog, Mercury,... • x86 is a pretty convincing UNCOL – pure software translation
