What is the primary purpose of a GPU?

  1. To perform complex mathematical calculations.

  2. To process graphics and images.

  3. To handle input and output operations.

  4. To store data and instructions.

Show answer
Correct Option: B
Explanation:

GPUs are specialized electronic circuits designed to accelerate the creation of images, videos, and other visual content.

Which programming model is commonly used for GPU programming in CUDA?

  1. Single Instruction Multiple Data (SIMD)

  2. Multiple Instruction Multiple Data (MIMD)

  3. Data Parallelism

  4. Task Parallelism

Show answer
Correct Option: A
Explanation:

CUDA employs the SIMD programming model, where a single instruction is executed on multiple data elements simultaneously.

What is the primary language used for programming GPUs in CUDA?

  1. C

  2. C++

Which API is commonly used for GPU programming in Vulkan?

  1. Compute Unified Device Architecture (CUDA)

  2. Open Computing Language (OpenCL)

  3. Vulkan

  4. DirectX

Show answer
Correct Option: C
Explanation:

Vulkan is a cross-platform API that provides low-level access to GPU hardware.

What is the primary language used for programming GPUs in Vulkan?

  1. C

  2. C++

  3. Python

  4. Java

Show answer
Correct Option: B
Explanation:

Vulkan programming is primarily done using C++, which provides extensions for GPU-specific operations.

Which programming model is commonly used for GPU programming in Vulkan?

  1. Single Instruction Multiple Data (SIMD)

  2. Multiple Instruction Multiple Data (MIMD)

  3. Data Parallelism

  4. Task Parallelism

Show answer
Correct Option: C
Explanation:

Vulkan employs the data parallelism programming model, where multiple data elements are processed concurrently.

What is the primary purpose of a GPU kernel?

  1. To define the data structures used in a GPU program.

  2. To specify the operations to be performed on the GPU.

  3. To manage the memory allocation and deallocation on the GPU.

  4. To handle the communication between the CPU and the GPU.

Show answer
Correct Option: B
Explanation:

GPU kernels contain the code that defines the operations to be executed on the GPU.

Which memory type is typically used for storing data that is frequently accessed by the GPU?

  1. Global Memory

  2. Shared Memory

  3. Local Memory

  4. Constant Memory

Show answer
Correct Option: B
Explanation:

Shared memory is a type of GPU memory that is shared among threads within a thread block, providing fast access to frequently used data.

Which memory type is typically used for storing data that is rarely accessed by the GPU?

  1. Global Memory

  2. Shared Memory

  3. Local Memory

  4. Constant Memory

Show answer
Correct Option: A
Explanation:

Global memory is a type of GPU memory that is accessible by all threads in a GPU program, but it has slower access speeds compared to other memory types.

What is the primary purpose of a thread block in GPU programming?

  1. To group threads that execute the same code.

  2. To manage the synchronization of threads.

  3. To allocate memory for thread-local data.

  4. To handle the communication between threads.

Show answer
Correct Option: A
Explanation:

Thread blocks are used to group threads that execute the same code, allowing for efficient execution of parallel tasks.

Which synchronization mechanism is commonly used in GPU programming to ensure that threads within a thread block execute in a synchronized manner?

  1. Barriers

  2. Mutexes

  3. Semaphores

  4. Condition Variables

Show answer
Correct Option: A
Explanation:

Barriers are commonly used in GPU programming to synchronize threads within a thread block, ensuring that all threads reach a specific point before proceeding further.

What is the primary purpose of a warp in GPU programming?

  1. To group threads that execute the same code.

  2. To manage the synchronization of threads.

  3. To allocate memory for thread-local data.

  4. To handle the communication between threads.

Show answer
Correct Option: A
Explanation:

Warps are groups of threads that execute the same code in a synchronized manner on a GPU.

Which programming model is commonly used for GPU programming in DirectX?

  1. Compute Unified Device Architecture (CUDA)

  2. Open Computing Language (OpenCL)

  3. Vulkan

  4. DirectX

Show answer
Correct Option: D
Explanation:

DirectX is a Microsoft-developed API that provides a comprehensive set of tools and technologies for game development and multimedia applications.
