jcuda-samples's Issues

jcuda 10

Windows 10

jcuda-samples/JCudaSamples/src/main/java/jcuda/runtime/samples/JCudaPrintDeviceInfo.java

Exception in thread "main" jcuda.CudaException: cudaErrorInsufficientDriver

JCuda samples for windows 64 pom.xml should reference jcuda-windows64 project

I had to add dependency jcuda-windows64 ver 6.5 to build jcuda-samples project

Cuda 11 support: UnsatisfiedLinkError

I would like to run some sample classes with Cuda 11 and JCuda 10.2.0. There seems to be compatibility problems:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Error while loading native library "JCurand-10.2.0-windows-x86_64"

Are there any plans to support Cuda 11?

Universal Callable ad Runnable Wrappers and thread safety test

To run Java cuda applications as regular ( not main ) class Collable and Runable wrappers are the prerequisit. Running Collable and Runnable classes requirs thread safety test. Both are almost done. I will assign these issues to myself

Version Problem?

I have installed the CUDA 11.1.1. Then I run the samples, I get the problem :Exception in thread "main" java.lang.UnsatisfiedLinkError: Error while loading native library "JCudaRuntime-11.1.1-windows-x86_64"

GL examples cause operating system call error

My computer enviroment is no problem: win10 64bit + cuda10.0 + jcuda 10.0.
Other samples are passed, but there are two bugs when I test all java source (directory: driver/gl.samples) related to opengl and JCudaRuntimeUnifiedMemory.java . The former reminds me with erro massage "CUDA_ERROR_OPERATING_SYSTEM on thread AWT-EventQueue-0", and after I debug it I only conclude that it comes from a wrong return of native methond "cuGraphicsGLRegisterBufferNative" ( it doesn't appear when I use visual studio 2012 to test the methond, I don't know why). The latter will fail with a not responding even a crash. Obviously, the system call isn't successful.

Insteed of 6 - the easy way to coordinate Java development by several teams

Threre are few simple steps which can ease coordination:

1. Label rcurrent project state as release candidate to postpone dealing with release procedure
2. Use intermediate Nexus repository before posting version to Maven Central. It is very simple to install Nexus and add Nexus repository to maven configuration for every developer. Nexus doesn't need even server because it can be deployed to any claud infra as Nexus Docker container. Everybody can submit changes to Nexus without formal release.
   Everybody can build his/her own project master branch using core project release candidate
   Development pipeline of every team can use Nexus in its development and automated testing

Hi, on the current head, I am seeing this:

Any suggestions?
