What happened and what to do
In a post published on July 11, 2026, the blog explains the communication between the CPU and GPU needed to launch a CUDA kernel. The post helps readers understand the work involved in this stage of execution.
For a company running GPU workloads, a practical response is to measure launch times and instrument CPU-to-GPU communication. These data can support performance analysis and guide application adjustments, without assuming that kernel execution is the only relevant factor.
How the consultancy can help
Wendelmaques can diagnose how your applications launch CUDA kernels, define an instrumentation scope, and implement and operate metrics collection to support performance analysis.
