You will need to add the folder containing the &quot;cl.exe&quot; file to your path environment variable. For example: 

    C:\Program Files\Microsoft Visual Studio 10.0\VC\bin

**Edit**: Ok, go to My Computer -&gt; Properties -&gt; Advanced System Settings -&gt; Environment Variables. Here look for &quot;PATH&quot; in the list, and add the path above (or whatever is the location of your cl.exe).

For new Visual Studio `cl.exe` is present in path =&gt; `C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.23.28105\bin\Hostx64\x64` 

x64 is for 64bit 

x86 is for 32bit

Solve this problem by adding this options to nvcc

    nvcc x.cu ...   -ccbin &quot;D:\Program Files\Microsoft Visual Studio 11.0\VC\bin&quot;

for example my compiler is VS2012. and cl.exe is in this dir

`cl.exe` is Microsoft&#39;s C/C++ compiler.  So the problem is that you don&#39;t have that installed where the command line can find it.

nvcc is only a front end for the CUDA specific part of the program. It must invoke a full compiler to finish the job. In this case it cannot find the Visual Studio compiler &#39;cl.exe&#39; 

Check paths, nvcc documentation etc.

I see that this is an old question but I recently got this error on my Visual Studio 2012 when I tried to build my CUDA project.  Apparently I had changed my CUDA project to the Nov 2012 pack, changing it back to the v110 that it usually is by default fixed this error.  

In Visual Studio, left click on the CUDA project, -&gt;properties-&gt;Configuration Properties-&gt; General -&gt; Platform toolset, and choose: Visual Studio 2012 (v110).

I could probably get it to work with the Nov 2012 pack, but the CUDA code does not use any of the additional functions of that pack, so it is not necessary. (That pack contains the variadic templates for C++11.)

I am trying to install Ruby 1.9.3 but am having problems.

I have a very simple Toshiba Laptop with i3 processor. Also, I do not have any expensive graphics card. In the display settings, I see **Intel(HD) Graphics** as display adapter. I am planning to learn some cuda programming. But, I am not sure, if I can do that on my laptop as it does not have any nvidia&#39;s cuda enabled GPU.

In fact, I doubt, if I even have a GPU o_o

So, I would appreciate if someone can tell me if I can do CUDA programming with the current configuration and if possible also let me know what does **Intel(HD) Graphics** mean? 

Can I run CUDA on Intel&#39;s integrated graphics processor?

I&#39;m trying to monitor a process that uses CUDA and MPI, is there any way I could do this, something like the command &quot;top&quot; but that monitors the GPU too?



A top-like utility for monitoring CUDA activity on a GPU

I am looking for help getting started with a project involving CUDA. My goal is to have a project that I can compile in the native g++ compiler but uses CUDA code. I understand that I have to compile my CUDA code in nvcc compiler, but from my understanding I can somehow compile the CUDA code into a cubin file or a ptx file.

Here are my questions:

1. How do I use nvcc to compile into a cubin file or a ptx file? Don&#39;t I need a -c or something?
2. Which file type do I want to use?
3. What are the g++ commands to correctly compile and link the project together?

Assume the following:

1. I have a file called &quot;main.cpp&quot; that has a main function in it and includes cuda.h.
2. I have another file called &quot;cudaFunc.cu&quot; that has CUDA code in it. Let&#39;s say, for instance, that I want to add two integer arrays that exist in main.cpp.

How can I compile CUDA code then link it to a C++ project?

Is there any quick command or script to check for the version of CUDA installed?

I found the manual of 4.0 under the installation directory but I&#39;m not sure whether it is of the actual installed version or not.

How to get the CUDA version?

This is a question about how to determine the CUDA grid, block and thread sizes. This is an additional question to the one posted [here][1].

Following this link, the answer from talonmies contains a code snippet (see below). I don&#39;t understand the comment &quot;value usually chosen by tuning and hardware constraints&quot;.

I haven&#39;t found a good explanation or clarification that explains this in the CUDA documentation. In summary, my question is how to determine the optimal `blocksize` (number of threads) given the following code:


    const int n = 128 * 1024;
    int blocksize = 512; // value usually chosen by tuning and hardware constraints
    int nblocks = n / nthreads; // value determine by block size and total work
    madd&lt;&lt;&lt;nblocks,blocksize&gt;&gt;&gt;mAdd(A,B,C,n);

How do I choose grid and block dimensions for CUDA kernels?

I have been using CUDA for a few weeks, but I have some doubts about the allocation of blocks/warps/thread.
**I am studying the architecture from a didactic point of view** (university project), so reaching peak performance is not my concern.

First of all, I would like to understand if I got these facts straight:

1. The programmer writes a kernel, and organize its execution in a grid of thread blocks.

2. Each block is assigned to a Streaming Multiprocessor (SM). Once assigned it cannot migrate to another SM.

3. Each SM splits its own blocks into Warps (currently with a maximum size of 32 threads). All the threads in a warp executes concurrently on the resources of the SM.

4. The actual execution of a thread is performed by the CUDA Cores contained in the SM. There is no specific mapping between threads and cores.

5. If a warp contains 20 thread, but currently there are only 16 cores available, the warp will not run.

6. On the other hand if a block contains 48 threads, it will be split into 2 warps and they will execute in parallel provided that enough memory is available.

7. If a thread starts on a core, then it is stalled for memory access or for a long floating point operation, its execution could resume on a different core.

Are they correct?

Now, I have a GeForce 560 Ti so according to the specifications it is equipped with 8 SM, each containing 48 CUDA cores (384 cores in total).

My goal is to make sure that every core of the architecture executes the SAME instructions. Assuming that my code will not require more register than the ones available in each SM, I imagined different approaches:

1. I create 8 blocks of 48 threads each, so that each SM has 1 block to execute. In this case will the 48 threads execute in parallel in the SM (exploiting all the 48 cores available for them)?

2. Is there any difference if I launch 64 blocks of 6 threads? (Assuming that they will be mapped evenly among the SMs)

3. If I &quot;submerge&quot; the GPU in scheduled work (creating 1024 blocks of 1024 thread each, for example) is it reasonable to assume that all the cores will be used at a certain point, and will perform the same computations (assuming that the threads never stall)?

4. Is there any way to check these situations using the profiler?

5. Is there any reference for this stuff? I read the CUDA Programming guide and the chapters dedicated to hardware architecture in &quot;Programming Massively Parallel Processors&quot; and &quot;CUDA Application design and development&quot;; but I could not get a precise answer.

How do CUDA blocks/warps/threads map onto CUDA cores?

I&#39;d like to extend my skill set into GPU computing. I am familiar with raytracing and realtime graphics(OpenGL), but the next generation of graphics and high performance computing seems to be in GPU computing or something like it.

I currently use an AMD HD 7870 graphics card on my home computer. Could I write CUDA code for this? (my intuition is no, but since Nvidia released the compiler binaries I might be wrong).

A second more general question is, Where do I start with GPU computing? I&#39;m certain this is an often asked question, but the best I saw was from 08&#39; and I figure the field has changed quite a bit since then. 

Is it possible to run CUDA on AMD GPUs?

I tried running sample programs provided at [NVIDIA&#39;s official site][1]. Most of the programs ran smoothly except few where I get similar error messages. How can I fix that? Here&#39;s a sample of error message I got after running a program named &quot;MatrixMul&quot;.

Error Message : Cannot find or open the PDB file

I have installed IntelliJ IDEA (13.1.1 #IC-135.480) and JDK 1.8.0 (x64) and I generated some GUI with the GUI Form designer. 

Then I ran the code and realized that something is not alright. 

Here is a Screenshot of my GUI:
![Buggy Rendering JDK 1.8.0][1]

The rendering of the Font seems to be not OK. Additionally the Button looses its Text, when I move my mouse over it.

So I installed JDK 1.7.0_40 (x64), recompiled the Project and ran it again.

The following Form appears, when i use JDK 1.7:
![Rendering OK JDB 1.7.0_40][2]

The Rendering seems to be OK and the Button is also OK.

So I installed the newest Graphics and Chipset drivers and much more, but the problem still exists.
Have you ever had such problems with Java Swing UIs? Could you help me to fix my problems? 
Any help would be greatly appreciated.


----------

UPDATE:
-------

 

I created a small Project with only 1 JTextArea and 1 JButton and i have the same rendering problems.

According to Andrew Thompson i changed the setSize() and I start from EDT. The Example below:

    package at.maeh.java.client.simpleTextClient;
    
    import javax.swing.*;
    import java.awt.*;
    
    public class SimpleClient extends JFrame {
        private JPanel panel1;
        private JTextArea textArea1 = new JTextArea();
        private JButton button1 = new JButton();
    
        public SimpleClient() {
            super(&quot;SimpleClient&quot;);
    
            // Panel
            panel1 = new JPanel();
            panel1.setLayout(new FlowLayout());
    
            // BUtton
            button1.setText(&quot;TestButton&quot;);
    
            // TextArea
            textArea1.setColumns(40);
            textArea1.setRows(15);
    
            // Add Components
            panel1.add(textArea1);
            panel1.add(button1);
    
            // Add to Frame
            this.getContentPane().add(panel1);
    
            // pack and set Visible
            pack();
            setVisible(true);
    
            System.out.println(&quot;Constructor EDT: &quot; + SwingUtilities.isEventDispatchThread());
        }
    
        public static void main(String[] args) {
            SwingUtilities.invokeLater(SimpleClient::new);
    
            System.out.println(&quot;Main EDT: &quot; + SwingUtilities.isEventDispatchThread());
        }
    }
       
The result is a simple JFrame with the Components in it.

![SimpleClient -&gt; Screenshot immediately after Start][3]

When I write some Text, or moove my mousePointer over the Button the components get rendered like this (Text: testsentence.123; Button-Label: TestButton)

![after writing - or mouse over][4]
