• GPGPU

  WhatGPU obviously stands for Graphics Processing Unit (the silicon powering the display you are using to read this blog post). The extra GP in front of that stands for General Purpose computing.So, altogether GPGPU refers to computing we can perform on GPU for purposes beyond just drawing on the screen. In effect, we can use a GPGPU a bit like we already use a CPU: to perform some calculation (that doesn’t have to have any visual element to it). The attraction is that a GPGPU can be orders of magnitude faster than a CPU.WhyWhen I was at the SuperComputing conference in Portland last November, GPGPUs were all the rage. A quick online search reveals many articles introducing the GPGPU topic. I'll just share 3 here: pcper (ignoring all pages except the first, it is a good consumer perspective), gizmodo (nice take using mostly layman terms) and vizworld (answering the question on "what's the big deal").The GPGPU programming paradigm (from a high level) is simple: in your CPU program you define functions (aka kernels) that take some input, can perform the costly operation and return the output. The kernels are the things that execute on the GPGPU leveraging its power (and hence execute faster than what they could on the CPU) while the host CPU program waits for the results or asynchronously performs other tasks.However, GPGPUs have different characteristics to CPUs which means they are suitable only for certain classes of problem (i.e. data parallel algorithms) and not for others (e.g. algorithms with branching or recursion or other complex flow control). You also pay a high cost for transferring the input data from the CPU to the GPU (and vice versa the results back to the CPU), so the computation itself has to be long enough to justify the overhead transfer costs. If your problem space fits the criteria then you probably want to check out this technology.HowSo where can you get a graphics card to start playing with all this? At the time of writing, the two main vendors ATI (owned by AMD) and NVIDIA are the obvious players in this industry. You can read about GPGPU on this AMD page and also on this NVIDIA page. NVIDIA's website also has a free chapter on the topic from the "GPU Gems" book: A Toolkit for Computation on GPUs.If you followed the links above, then you've already come across some of the choices of programming models that are available today. Essentially, AMD is offering their ATI Stream technology accessible via a language they call Brook+; NVIDIA offers their CUDA platform which is accessible from CUDA C. Choosing either of those locks you into the GPU vendor and hence your code cannot run on systems with cards from the other vendor (e.g. imagine if your CPU code would run on Intel chips but not AMD chips). Having said that, both vendors plan to support a new emerging standard called OpenCL, which theoretically means your kernels can execute on any GPU that supports it. To learn more about all of these there is a website: gpgpu.org. The caveat about that site is that (currently) it completely ignores the Microsoft approach, which I touch on next.On Windows, there is already a cross-GPU-vendor way of programming GPUs and that is the DirectX API. Specifically, on Windows Vista and Windows 7, the DirectX 11 API offers a dedicated subset of the API for GPGPU programming: DirectCompute. You use this API on the CPU side, to set up and execute the kernels that run on the GPU. The kernels are written in a language called HLSL (High Level Shader Language). You can use DirectCompute with HLSL to write a "compute shader", which is the term DirectX uses for what I've been referring to in this post as a "kernel". For a comprehensive collection of links about this (including tutorials, videos and samples) please see my blog post: DirectCompute.Note that there are many efforts to build even higher level languages on top of DirectX that aim to expose GPGPU programming to a wider audience by making it as easy as today's mainstream programming models. I'll mention here just two of those efforts: Accelerator from MSR and Brahma by Ananth. Comments about this post welcome at the original blog.

• DirectCompute

  In my previous blog post I introduced the concept of GPGPU ending with:On Windows, there is already a cross-GPU-vendor way of programming GPUs and that is the Direct X API. Specifically, on Windows Vista and Windows 7, the DirectX 11 API offers a dedicated subset of the API for GPGPU programming: DirectCompute. You use this API on the CPU side, to set up and execute the kernels on the GPU. The kernels are written in a language called HLSL (High Level Shader Language). You can use DirectCompute with HLSL to write a "compute shader", which is the term DirectX uses for what I've been referring to in this post as "kernel".In this post I want to share some links to get you started with DirectCompute and HLSL.1. Watch the recording of the PDC 09 session: DirectX11 DirectCompute.2. If session recordings is your thing there are two more on DirectCompute from nvidia's GTC09 conference 1015 (pdf, mp4) and 1411 (mp4 plus the presenter's written version of the session).3. Over at gamedev there is an old Compute Shader tutorial. At the same site, there is a 3-part blog post on Compute Shader: Introduction, Resources and Addressing.4. From PDC, you can also download the DirectCompute Hands On Lab.5. When you are ready to get your hands even dirtier, download the latest Windows DirectX SDK (at the time of writing the latest is dated Feb 2010).6. Within the SDK you'll find a Compute Shader Overview and samples such as: Basic, Sort, OIT, NBodyGravity, HDR Tone Mapping.7. Talking of DX11/DirectCompute samples, there are also a couple of good ones on this URL.8. The documentation of the various APIs is available online. Here are just some good (but far from complete) taster entry points into that: numthreads, SV_DispatchThreadID, SV_GroupThreadID, SV_GroupID, SV_GroupIndex, D3D11CreateDevice, D3DX11CompileFromFile, CreateComputeShader, Dispatch, D3D11_BIND_FLAG, GSSetShader.

• Best of "The Moth" 2009

  Not wanting to break the tradition (2004, 2005, 2006, 2007, 2008) below are some blog posts I picked from my blogging last year. As you can see by comparing with the links above, 2009 marks my lowest output yet with only 64 posts, but hopefully the quality has not been lowered ;-) 1. Parallel Computing was a strong focus of course. You can find links to most of that content aggregated in the post where I shared my entire parallelism session. Related to that was the link to the screencast I shared of the Parallel Computing Features Tour.2. Parallel Debugging is obviously part of the parallel computing links above, but I created more in depth content around that area of Visual Studio 2010 since it is the one I directly own. I aggregated all the links to that content in my post: Parallel Debugging.3. High Performance Computing through clusters is an area I'll be focusing more next year (besides parallelism on a single node on the client captured above) and I started introducing the topic on my blog this year. Read the (currently) 6 posts bottom up from my category on HPC.4. Windows 7 Task Manager. In April I shared a screenshot which was the most "borrowed" item from my blog (I should have watermarked it ;-)5. Windows Phone non-support in VS2010. Did my bit to spread clarification of the story.6. Window positions in Visual Studio is a long post, but one that I strongly advise all VS users to read and benefit from.7. Bug Triage gives you a glimpse into one thing all (Microsoft) product teams do.If you haven't yet, you can subscribe via one of the options on the left. Either way, thank you for staying tuned… Happy New Year! Comments about this post welcome at the original blog.

• Parallel Debugging

  Using Visual Studio 2010 parallel debugging is easy. Two new debugging windows provide a total view of the internals of your PPL and TPL applications with hints on where to start investigations. These are not mere extensions to VS, but tightly integrated with the rest of the debugger experience, so you don't need to learn many new techniques. Use them in your program to eclipse bugs from existence!One of the most FAQ I receive is links to VS2010 parallel debugging content and rather than keep sending many, I decided to gather them all under one permalink, hence this multi link blog post.- MSDN Magazine article on Parallel Debugging.- Screencast of sample code from the article.- MSDN Walkthrough: Debugging a Parallel Application (VB, C++, C#).- Screencast of walkthrough for Parallel Stacks.- Screencast of walkthrough for Parallel Tasks.- MSDN "How To" on Parallel Tasks.- MSDN "How To" on Parallel Stacks.- Detailed blog post on Parallel Tasks.- Detailed blog post on Parallel Stacks.- Detailed blog post on Parallel Stacks - Tasks View.- Detailed blog post on Parallel Stacks - Method View.- Download slides on Parallel Tasks and Parallel Stacks (pptx).If you have questions on these, please post to any of the parallel computing forums or the debugging forum (your question will be routed to me if nobody else can answer it).

• Slides and code for MPI Cluster Debugger

  I've blogged before about the MPI Cluster Debugger in VS2010 that facilitates launching the application on the cluster and attaching the debugger (btw, a shorter version of the screencast I link to there, is here).There have been requests for the code I use in the screencast, so please find a ZIP with that code.There have also been requests for a PowerPoint deck to use when showing this feature to others. Feel free to download some slides I threw together the other day. Comments about this post welcome at the original blog.

• MPI Project Template for VS2010

  If you are developing MS MPI applications with Visual Studio 2010, you are probably tired of following some tedious steps for every new C++ project that you create, similar to the following:1. In Solution Explorer, right-click YourProjectName, then click Properties to open the Property Pages dialog box.2. Expand Configuration Properties and then under VC++ Directories place the cursor at the beginning of the list that appears in the Include Directories text box and then specify the location of the MS MPI C header files, followed by a semicolon, e.g.C:\Program Files\Microsoft HPC Pack 2008 SDK\Include;3. Still under Configuration Properties and under VC++ Directories place the cursor at the beginning of the list that appears in the Library Directories text box and then specify the location of the Microsoft HPC Pack 2008 SDK library file, followed by a semicolon, e.g.if you want to build/debug 32bit application:C:\Program Files\Microsoft HPC Pack 2008 SDK\Lib\i386;if you want to build/debug 64bit application:C:\Program Files\Microsoft HPC Pack 2008 SDK\Lib\amd64;4. Under Configuration Properties and then under Linker, select Input and place the cursor at the beginning of the list that appears in the Additional Dependencies text box and then type the name of the MS MPI library, i.e.msmpi.lib;5. In the code file#include "mpi.h"6. To debug the MPI project you have just setup, under Configuration Properties select Debugging and then switch the Debugger to launch combo value from Local Windows Debugger to MPI Cluster Debugger.Wouldn't it be great if at C++ project creation time you could choose an MPI Project Template that included the steps/configurations above? If you answered "yes", I have good news for you courtesy of a developer on our team (Qing). Feel free to download from Visual Studio gallery the MPI Project Template.

• Code for Parallelism Features Tour

  Last year I linked to a screencast that shows off many VS2010 features delivered by the Parallel Computing team.There have been requests for the code used to demonstrate the features. Like with all my screencasts, you can see all the code in action, so you could simply type it in. To save you doing that though, you may download the two files with the demo code here: MM.cs and Program.cs. HTH. Comments about this post welcome at the original blog.

• MPI Cluster Debugger launch integration in VS2010

  Let's assume that you have all the HPC bits installed and that you have existing MPI code (or you created a "Hello World" project using the MPI project template). Of course, you create a single MPI application and at runtime it will correspond to multiple processes (of the same app) launched on multiple nodes (i.e. machines) on the cluster. So how do you debug such a situation by simply hitting the familiar "F5" keystroke (i.e. Debug - Start Debugging)?WATCH IT INSTEAD OF READING ABOUT ITIf you can't bear to read through all the details below, just watch this 19-minute screencast explaining this VS2010 feature. Alternatively, or even additionally, keep on reading.REQUIREMENTWhen you debug an MPI application, you would want the copying of resources from your client machine (where Visual Studio is installed) to each compute node (where Windows HPC Server is installed) to take place automatically for you. 'Resources' in the previous sentence includes your application binary, plus any binary or data dependencies it may have, plus PDBs if needed, plus the debug CRT of the correct bitness, plus msvsmon for remote debugging to work. You would also want, after copying is complete, to have your app and msvsmon launched and attached so that you can hit breakpoints back in Visual Studio on your client machine. All these thing that you would want are delivered in VS2010.STEPS TO F51. In your MPI project where you have placed a breakpoint go to Project Properties - Configuration Properties - Debugging. Ensure the "Debugger to launch" combo box value is set to MPI Cluster Debugger.2. There are a whole bunch of properties here and typically you can ignore all of them except one: Run Environment. By default it is set to run 1 process on your local machine and if you change the number after that to, for example, 4 it will launch 4 processes of your app on your local machine.You want this to run on your cluster though, so go to the dropdown arrow at the end of the Run Environment cell and open it to expose the "Edit Hpc node" menu which opens the Node Selector dialog:In this dialog you can enter (or pick from a list) the cluster head node name and then the number of processes you want to execute on the cluster and then hit OK and… you are done.3. Press F5 and watch your breakpoint get hit (after giving it some time for copying, remote execution, attachment and symbol resolution to take place).GOING DEEPERIn the MPI Cluster Debugger project properties above, you can see many additional properties to the Run Environment. They are all optional, but you may want to understand them in order to fine tune your cluster debugging. Read all about each one of these on the MSDN page Configuration Properties for the MPI Cluster Debugger.In the Node Selector dialog above you can see more options than just the Head Node name and Number of Process to run. They should be self-explanatory but I also cover them in depth in my screencast showing you an example of why you would choose to schedule processes per core versus per node. You can also read about these options on MSDN as part of the page How to: Configure and Launch the MPI Cluster Debugger.To read through an example that touches on MPI project creation, project properties, node selector, and also usage of MPI with OpenMP plus MPI with PPL, read the MSDN page Walkthrough: Launching the MPI Cluster Debugger in Visual Studio 2010.Happy MPI debugging!

• Managed code and the Shell – Do?

  Back in 2006 I wrote a blog post titled: Managed code and the Shell – Don't!. Please visit that post to see why that advice was given.The crux of the issue has been addressed in the latest CLR via In-Process Side-by-Side Execution. In addition to the MSDN documentation I just linked, there is also an MSDN article on the topic: In-Process Side-by-Side.Now, even though the major technical impediment seems to be removed, I don’t know if Microsoft is now officially supporting managed extensions to the shell. Either way, I noticed a CodePlex project that is marching ahead to enable exactly that: Managed Mini Shell Extension Framework. Not much activity there, but maybe it will grow once .NET 4 is released... Comments about this post welcome at the original blog.

• Extension Manager in Visual Studio 2010

  One of the powerful aspect of Visual Studio is its ability to be extended and many people do that. You can find numerous extensions at the Visual Studio Gallery. The VSX team links to a 4-part blog series on how to create and share templates. You can also look find extension examples on the vsx code gallery.With Visual Studio 2010, you can search for items and install them directly from within Visual Studio's new Extension Manager. You launch it from the Tools menu:When the dialog comes up, be sure to explore the various actionable areas on the left and also note the search on the right. For example, I typed "MP" and it quickly filtered the list to show me the MPI Project Template:Others have written about this before me, just bing Extension Manager (and note that Beta2 introduced changes, some of which you can witness in the screenshot above).

• Dump debugging with Parallel Stacks

  One of the areas where we fixed many bugs for Beta2 in our parallel debugging windows is with regards to managed dump debugging. So it was really cool to see Tess use the Parallel Stacks window in that scenario in her video demo with Scott.Other than the neat ability to open managed dumps in VS2010, Parallel Stacks was the only debugging feature she needed for diagnosing the issue! Check out the video, definitely worth 10 minutes of your time. Comments about this post welcome at the original blog.

• android View not attached to window manager...

  - by Daniel Benedykt

  Hi I am having some of the following exceptions: java.lang.IllegalArgumentException: View not attached to window manager at android.view.WindowManagerImpl.findViewLocked(WindowManagerImpl.java:355) at android.view.WindowManagerImpl.updateViewLayout(WindowManagerImpl.java:191) at android.view.Window$LocalWindowManager.updateViewLayout(Window.java:428) at android.app.Dialog.onWindowAttributesChanged(Dialog.java:596) at android.view.Window.setDefaultWindowFormat(Window.java:1013) at com.android.internal.policy.impl.PhoneWindow.access$700(PhoneWindow.java:86) at com.android.internal.policy.impl.PhoneWindow$DecorView.drawableChanged(PhoneWindow.java:1951) at com.android.internal.policy.impl.PhoneWindow$DecorView.fitSystemWindows(PhoneWindow.java:1889) at android.view.ViewRoot.performTraversals(ViewRoot.java:727) at android.view.ViewRoot.handleMessage(ViewRoot.java:1633) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4338) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) at dalvik.system.NativeStart.main(Native Method) I have google it and see that it has something to do with popups and turning the screen, but there is no reference to my code. The questions are: 1) is there a way to find out exactly when this issue is happening? 2) other than turning the screen, is there another event or action that triggers this error? 3) how do I prevent this to happen? Thanks

• Byte array serialization in JSON.NET

  - by Daniel Earwicker

  Given this simple class: class HasBytes { public byte[] Bytes { get; set; } } I can round-trip it through JSON using JSON.NET such that the byte array is base-64 encoded: var bytes = new HasBytes { Bytes = new byte[] { 1, 2, 3, 4 } }; // turn it into a JSON string var json = JsonConvert.SerializeObject(bytes); // get back a new instance of HasBytes var result1 = JsonConvert.DeserializeObject<HasBytes>(json); // all is well Debug.Assert(bytes.Bytes.SequenceEqual(result1.Bytes)); But if I deserialize this-a-wise: var result2 = (HasBytes)new JsonSerializer().Deserialize( new JTokenReader( JToken.ReadFrom(new JsonTextReader( new StringReader(json)))), typeof(HasBytes)); ... it throws an exception, "Expected bytes but got string". What other options/flags/whatever would need to be added to the "complicated" version to make it properly decode the base-64 string to initialize the byte array? Obviously I'd prefer to use the simple version but I'm trying to work with a CouchDB wrapper library called Divan, which sadly uses the complicated version, with the responsibilities for tokenizing/deserializing widely separated, and I want to make the simplest possible patch to how it currently works.

• Windows 7 UAC manifest file for some VB6 application

  - by Daniel

  Hi, all, I have an old VB6 application which should run on Windows 7 (with UAV set to the default level, 3 of 4 IMHO). It has the functionality to update itself, and Windows 7 is now complaining that it would modify the computer (At least windows 7 is right here). I was able to run it in Vista with some kind of manifest file, but this does not seem to work anymore (which is the intended behaviour if I think of it). The manifest file is this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.1.0.24" processorArchitecture="X86" name="IKOfficeAppStarter" type="win32"/> <description>IKOffice Starter</description> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="X86" publicKeyToken="6595b64144ccf1df" language="*"/> </dependentAssembly> </dependency> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="true"/> </requestedPrivileges> </security> </trustInfo> </assembly> The manifest can be found near the exe "IKOffice Starter.exe" and is called "IKOffice Starter.exe.manifest", which should be okey. Currently the Shield Icon has gone from my .exe, but when try to start the software, i get the message "Der angeforderte Vorgang erfordert höhere Rechte", or translated to english "the requested operation requires elevation". What can I do to stop windows to bug me anymore, so I can install this application on our clients computers. Hey, I already told Windows to run it as Invoker, so why is it still complaining?
