QUESTION
I am a newbie with CUDA. I'm learning some basic things because I want to use CUDA in other project. I have wrote this code in order to add all the elements from a squared matrix 8x8 which has been filled with 1's so the result must be 64.
...ANSWER
Answered 2021-May-05 at 16:14There are a number of issues:
- You are creating a 1-D grid (grid configuration, block configuration) so your 2-D indexing in kernel code (i,j, or x,y) doesn't make any sense
- You are passing
sumby value. You cannot retrieve a result that way. Changes in the kernel tosumwon't be reflected in the calling environment. This is a C++ concept, not specific to CUDA. Use a properly allocated pointer instead. - In a CUDA multithreading environment, you cannot have multiple threads update the same location/value without any control. CUDA does not sort out that kind of access for you. You must use a parallel reduction technique, and a simplistic approach here could be to use atomics. You can find many questions here on the
cudatag discussing parallel reductions. - You're generally confusing pass by value and pass by pointer. Items passed by value can be ordinary host variables. You generally don't need a
cudaMallocallocation for those. You also don't usecudaMallocon any kind of variable except a pointer. - Your use of
cudaMemcpyis incorrect. There is no need to take the address of the pointers.
The following code has the above items addressed:

i´m migrating my node.js app to typescript and is the first time for me doing this, for some reason after declare and create my class when i create a new instance of the class instance of my class controller get this error after making the request to the end point:
...ANSWER
Answered 2020-Dec-09 at 21:18The problem is this is undefined since you're passing a reference to the categoryController.getCategories function and not the class context itself. Instead do this:
router.get('/', categoryController.getCategories.bind(categoryController);
Alternatively you can bind getCategories within the CategoryController constructor.

I need to run a command with a nightly build of FFMPEG to report a bug on the concat protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.

I'm creating a UWP app, and i'm trying to read an image from a file to a Byte[]. I don't know why but i'm always getting the exception from whatever file path... I tried running that same method File.ReadAllBytes from a different project and it didn't throw the exception. Is it a problem of permissions in my project?

Answered 2019-Dec-30 at 01:05Rather than accessing files directly by path, it is recommended to use FileOpenPicker to open the file in UWP.

I'm currently working on data about an ultramarathon. There's many checkpoints with timestamps for each runner's time on that checkpoint, but as I'm trying to study the split times I need to calculate the half times, which is not a problem in itself, but I'm having issues with formatting.
The data I scraped looks like this:

Here's the deal:
I have these tables, which are all for making a Steam-like application (downloading games, talking with friends, etc). My problem comes when I want to know which of my friends play each of my games (Say I play Minecraft, I would want to see which of my friends play Minecraft as well), and I'm struggling to form a query which will tell me that. I'd thought this could possibly be made with the help of the EXCEPT keywork, but I've tried to no avail.
Maybe this will help understand what I want to end up getting:
As you can see, I have Crashex Legends in common with Migue, and also Crashex Legends and Overwatch with Test. I want to see only one result per friend per common game, so that I would only see results 1, 8 and 9.

Answered 2019-May-16 at 19:50You need to JOIN to UserGames twice, instead of once with an OR.
JOIN once with User1 and alias UserGames as UG1;
Then JOIN again with User2 and alias UserGames as UG2.

this is my package.json
...ANSWER
Answered 2017-Dec-14 at 12:28Downgrade the version of ng2-img-max to 2.1.0 because the developer updates dependencies in 2.1.4 for supporting angular 5.
For more information see the commits of 2.1.4:
https://github.com/bergben/ng2-img-max/compare/2.1.4...master
You see that devDependencies of 2.1.4 require angular 5:
