1 Seminarbeschreibung Windows Server 2008 Developing High-performance Applications using Microsoft Windows HPC Server 2008 Einleitung: In dieser Schulung lernen die Entwickler - High-Performance Computing (HPC) Anwendungen für Microsoft Windows HPC Server 2008 zu entwickeln. Sie lernen das Produkt Microsoft Windows HPC Server 2008, die Vorgehensweisen für Design, Debugging, Tuning und Betrieb von High-Performance Computing-Anwendungen unter HPC Server 2008 kennen. Ebenfalls werden Technologien für das Erstellen von HPC- Anwendungen vorgestellt, einschließlich Parametric Sweep, Multithreading, OpenMP,.NET Task Parallel Library, MPI, MPI.NET und der SOA-basierte Ansatz für HPC Server. Die Teilnehmer entwickeln in Visual C++ sowie C# und arbeiten sowohl mit verwaltetem (managed) als auch nicht-verwaltetem (unmanaged) Code. Dauer: 5 Tage Empfohlene Vorkenntnisse: Entwickler mit sehr guten Kenntnissen bezüglich Windows Plattformen Visual Studio C++ und/oder C# Zielgruppe: Softwareentwickler

2 Inhalte: Introduction to High-Performance Computing and HPC Server 2008 Motivation for HPC Brief product history of CCS and HPCS Brief overview of HPC Server 2008 components, job submission, scheduler Product differentiators Software development technologies: parametric sweep, threads, OpenMP, MPI, SOA, etc. Measuring performance linear speedup Predicting performance Amdahl s law Multi-threading for Performance Multi-threading for responsiveness and performance The costs of multi-threading Structured, fork-join parallelism Multi-threading in C# using the.net Thread class Multi-threading in VC++ using the Windows API Load balancing Scheduling multi-threaded apps on Windows HPC Server The Dangers of Multithreading Race conditions Critical sections Starvation Livelock Deadlock Compiler and language implications Memory models Locks Interlocking Lock-free designs The HPCS Job Scheduler Throughput vs. performance Nodes vs. sockets vs. cores Jobs vs. Tasks Job and task states Default scheduling policies The impact of job priorities and job preemption Job resources and dynamic growing / shrinking Submission and activation filters Parallel Application Design Two sample design problems Foster s method Common problem decompositions Common communication patterns Computation vs. communication Design patterns: master-worker, pipeline, map-reduce, SOA, parametric sweep, and more

3 Introduction to OpenMP What is OpenMP? Shared-memory programming Using OpenMP in Visual Studio with VC++ Parallel regions Data parallelism Load balancing, static vs. dynamic scheduling Scheduling OpenMP apps on Windows HPC Server Running and measuring performance on the cluster Barriers Critical sections Synchronization approaches Implementing common design patterns conditional, task, master-worker, nested Data coherence and flushing Environment variables Common pitfalls Introduction to the.net Task Parallel Library What is the TPL? Moving from threads to tasks Using the TPL in Visual Studio with C# Parallel.For Data and task parallelism Synchronization approaches Concurrent data structures Scheduling TPL-based apps on Windows HPC Server Interfacing with HPCS-based Clusters Cluster Manager Job Manager Job Description Files clusrun Console window PowerShell Scripts Programmatic access via HPCS API v2.0 Intro to SOA with HPC Server 2008 Service-oriented architectures SOA and WCF Mapping SOA onto Jobs and the Job Scheduler Private vs. shared sessions Secure vs. insecure sessions

4 Create SOA-based Apps with HPC Server 2008 Service-side programming Service configuration Client-side programming WCF configuration and tracing General Performance Tuning of Parallel Applications Performance counters Heat map in Windows HPC Server 2008 Customizing the heat map perfmon xperf (aka the Windows Performance Toolkit) SOA tuning What to look for Other tools Introduction to MPI Shared-memory vs. distributed-memory The essence of MPI programming message-passing SPMD Microsoft MPI Using MSMPI in Visual Studio with VC++ MPI Send and Receive mpiexec Scheduling MPI apps on Windows HPC Server Data Parallelism and MPI s Collective Operations Data parallelism in MPI A real world example Broadcast Scatter Gather Barriers Reductions Defining your own reduction operator Common pitfalls MPI.NET Why MPI.NET? Using MPI.NET in Visual Studio with C# Type-safe Send and Receive Collective operations in MPI.NET Scheduling MPI.NET apps on Windows HPC Server Using MPI Debugging, Tracing, and Other Tools Local debugging with Visual Studio Remote debugging with Visual Studio General MPI tracing Tracing with ETW (Event Tracing for Windows) Trace visualization Other tools for MPI developers

5 Designing MPI Applications Hiding latency by overlapping computation and communication Avoiding deadlock Hybrid designs involving both MPI and OpenMP Buffering Error handling I/O and large datasets MPI-2 Groups Communicators Topologies Non-scalar data: packing/unpacking, non-contiguous arrays, and user-defined datatypes MPI I/O Remote memory access [ Dynamic process creation is not supported in MSMPI ] Excel-based HPC Apps Excel as a computation engine Performing Excel computations on Windows HPC Server 2008 Using Excel Services Using Excel UDFs Future versions of Excel and HPC Server Porting UNIX apps to Windows HPC Server 2008 The most common porting issues 32-bit to 64-bit UNIX calls Manual porting of UNIX code Cygwin MinGW Microsoft SUA Subsystem for UNIX-based Applications Open Grid Forum HPC Basic Profile What is the OGF HPC Basic Profile? Platform-neutral job submission JSDL Job Submission Description Language Enabling in Windows HPC Server 2008 Setup and Administration of Windows HPC Server 2008 Hardware requirements Software requirements Initial decisions Headnode setup Compute node setup Broker node setup Developer machine setup Diagnostics Maintenance including performance Troubleshooting
