I want to check the free memory on the device while executing a CUDA kernel. cuMemGetInfo(&free, &total) is a host (CPU) based command which gives free memory on the Device.

But is there any way to check free memory inside a CUDA kernel code during execution ?

Use profiler - The NVIDIA Visual Profiler is a cross-platform performance profiling tool that delivers developers vital feedback for optimizing CUDA C/C++ applications.

First introduced in 2008, Visual Profiler supports all 350 million+ CUDA capable NVIDIA GPUs shipped since 2006 on Linux, Mac OS X, and Windows.

The NVIDIA Visual Profiler is available as part of the CUDA Toolkit.
