Kudzika Kwakadzika
CUDA organizes work into grids, blocks, and threads. A kernel is a function launched across GPU threads. SIMT means groups of threads execute instructions on per-thread data; divergence within a warp can reduce efficiency. Global-memory coalescing matters because neighboring threads accessing nearby addresses can be served efficiently. Shared memory can enable reuse but requires explicit synchronization and careful layout. Frameworks often call CUDA libraries without requiring users to write raw CUDA.
Kuitwa muNyika yeChokwadi
Launch a kernel over a grid of thread blocks.
Use shared memory when threads in a block can reuse data.
Inspect memory transactions and occupancy when profiling.
Use higher-level libraries when they implement the needed operation.
Ramangwana reCUDA uye GPU Chirongwa
CUDA tools and abstractions continue to evolve. Profile on target hardware and compare optimized library or compiler-generated implementations before maintaining a custom kernel.

What is CUDA and GPU Programming?
CUDA is NVIDIA’s parallel-computing platform and programming model for running kernels on GPUs.
MuCUDA terminology, chii chinonzi 'kernel'?
MuCUDA kernel ibasa rakatangwa kuti riite panguva imwe chete muzviuru zveGPU tambo, imwe neimwe ichishanda pane dzakasiyana data.
Chii chinonzi SIMT execution modhi inorevei?
SIMT (Single Instruction, Multiple Threads) zvinoreva mapoka eshinda anoita rairo yakafanana pazvidimbu zvakasiyana zve data, yakanakira matrix math.
Nei PyTorch uye TensorFlow isingawanzoda vashandisi kunyora mbishi CUDA?
Aya masisitimu anoputira akakwenenzverwa eCUDA maraibhurari (cuDNN, cuBLAS), saka vashandisi vanowana GPU kukwidziridza pasina kunyora yakaderera-level kernels.
Chii chinonzi 'warp divergence' uye nei ichikuvadza kuita?
Warp iboka re (kazhinji 32) shinda; kana vakatora matavi akasiyana, iyo Hardware inoteedzera nzira, ichiparadza parallel throughput.
Nei 'coalesced' memory yekuwana yakakosha muCUDA?
Kana tambo dzakavakidzana dzichiwana kero dzekurangarira dzakavakidzana, iyo Hardware inogona kusanganisa izvo zvinoverengerwa, zvinoshamisa kuvandudza ndangariro throughput.
