OpenCL 2.0 Coarse-Grained SVM: Skip Copies, Not Synchronization
Coarse-grained shared virtual memory can replace explicit OpenCL buffer copies, but only with OpenCL 2.0 and strict host-device synchronization.

openclWhen MATLAB's gpuArray Pays Off: A Practical Decision Guide for GPU Acceleration
MATLAB's gpuArray can deliver 5–20× speed-ups, but only for large arrays and supported functions. Learn when the GPU transfer tax is worth paying and how to verify results.
matlabOpenCL 2.0 Fine-Grained SVM: When Pointer Sharing Beats Explicit Buffers
OpenCL 2.0 fine-grained SVM lets kernels dereference host-built pointers directly — great for linked lists and graphs, wasteful for dense arrays. Here's how to check support, use it, and benchmark the trade-off.
Speeding Up MATLAB Matrix Operations on a GPU with gpuArray
Move large MATLAB matrix and FFT workloads to a CUDA GPU with gpuArray: environment checks, transfer-overhead pitfalls, honest timing with wait(gpuDevice), and when the GPU is not worth it.
Designing Kaggle Kernels Around the 90-Minute Wall: Runtime Limits That Shape Your Code
Kaggle kernels terminate at the wall-clock limit with no checkpoint and no warning. Here's how to design experiments around timeouts, GPU quotas, and a fixed package set.
