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.

Overview
-
Focus on the information that matters
Quickly identify potential performance bottleneck issues in your applications using highly configurable tables and graphical views
-
Automated performance analysis
Perform automated analysis of your application to identify performance bottlenecks and get optimization suggestions that can be used to improve performance
-
*New* in CUDA 5: nvprof
Collect and view profiling daya from the command-line
-
Unified CPU and GPU Timeline
View CUDA activity occurring on both CPU and GPU in a unified time line, including CUDA API calls, memory transfers and CUDA launches.
-
CUDA API trace
View all memory transfers, kernel launches, and other API functions on the same timeline
-
Drill down to raw data
Gain low-level insights by looking at performance metrics collected directly from GPU hardware counters and software instrumentation.
-
Compare results across multiple sessions
Confirm performance improvements by comparing against previous sessions
-
Analyze data collected from remote systems
Use the command line profiler using environment variables to collect data from multiple systems and analyze the results in Visual Profiler
-
*New* in CUDA 5: Kernel Instance Analysis
Pinpoints optimization oppotunities at specific source lines within kernels.
-
*New* in CUDA 5: Support for Concurrent Kernel Execution
Profiler timeline and nvprof output will show multiple kernel instances
-
*New* in CUDA 5: cudaProfilerStart() & cudaProflerStop()
Enables focused profiling of user applications
-
*New* in CUDA 5: Support for NVIDIA Tools Extension (NVTX)
