* Updated toolchain for cross-compilation for Tegra Linux platforms. * Updated toolchain for cross-compilation for Tegra Linux platforms.
* Repository has been updated with consistent code formatting across all samples
* Many small code tweaks and bug fixes (see commit history for details)
* Removed the following outdated samples:
* `1_Utilities`
* `bandwidthTest` - this sample was out of date and did not produce accurate results. For bandwidth
testing of NVIDIA GPU platforms, please refer to [NVBandwidth](https://github.com/NVIDIA/nvbandwidth)

# bandwidthTest - Bandwidth Test
## Description
This is a simple test program to measure the memcopy bandwidth of the GPU and memcpy bandwidth across PCI-e. This test application is capable of measuring device to device copy bandwidth, host to device copy bandwidth for pageable and page-locked memory, and device to host copy bandwidth for pageable and page-locked memory.
## Key Concepts
CUDA Streams and Events, Performance Strategies
