Added sample cupti_trace_injection to show how to build an injection library using the activity and callback APIs which can be used to trace any CUDA application.

Added sample cupti_correlation to show correlation between CUDA APIs and corresponding GPU activities.

A new API cuptiActivityEnableAndDump is added to provide snapshot of certain activities like device, context, stream, NVLINK and PCIE at any point during the profiling session.

#WHAT HAPPENS WHEN INSTALL CUDA TOOLKIT UBUNTU DRIVERS#

This activity can only be enabled for drivers of version 515 and above. This is intended to reduce overheads involved in tracing each node separately.

A new activity kind CUPTI_ACTIVITY_KIND_GRAPH_TRACE and activity record CUpti_ActivityGraphTrace are introduced to represent the execution for a graph without giving visibility about the execution of its nodes.

Updates in CUDA Toolkit 11.7ĬUPTI has made the following changes as part of the CUDA Toolkit 11.7 release: New Features

See the CUPTI User Guide for a complete listing of hardware and software event counters available for performance analysis tools. The PC Sampling gives the number of samples for each source and assembly line with various stall reasons.

Device-wide sampling of the program counter (PC).

Metrics attribution at the high-level source code and the executed assembly instructions.

Range profiling to enable metric collection over concurrent kernel launches within a range.

Enables automated bottleneck identification based on metrics such as instruction throughput, memory throughput, and more.

Memory load/store events and throughput.

Utilization metrics for various hardware units.

Profile hardware and software event counters, including:.

Normalized timestamps for CPU and GPU trace.

CUDA Unified Memory trace for transfers from host to device, device to host, device to device and page faults on CPU and GPU etc.

GPU workload trace for the activities happening on the GPU, which includes kernel executions, memory operations (e.g., Host-to-Device memory copies) and memset operations.

#WHAT HAPPENS WHEN INSTALL CUDA TOOLKIT UBUNTU UPDATE#

There is currently no CUPTI update to the CUDA Toolkit 11.7. Normally packaged with the CUDA Toolkit, NVIDIA occasionally uses this page to provide CUPTI improvements and bug fixes between toolkit releases. Using these CUPTI APIs, independent software developers can create profiling tools that provide low and deterministic profiling overhead on the target system, while giving insight into the CPU and GPU behavior of CUDA applications. Provides a set of APIs targeted at ISVs creating profilers and other Profiling and tracing tools that target CUDA applications. It should give output something like this nvcc: NVIDIA (R) Cuda compiler driverĬopyright (c) 2005-2016 NVIDIA CorporationĬuda compilation tools, release 8.0, V8.0.The NVIDIA® CUDA Profiling Tools Interface (CUPTI) is a dynamic library that enables the creation of

You can run below command from any directory nvcc -V Once you find this location you can then do the following (replacing $ If that doesn't work, see "Redhat distributions" below. To find the file, you can use: whereis cudnn.h You first need to find the installed cudnn file and then parse this file. My answer shows how to check the version of CuDNN installed, which is usually something that you also want to verify. With TensorFlow, you might consider using CuDNN v4 instead of v5. When you get an error like F tensorflow/stream_executor/cuda/cuda_dnn.cc:427] could not set cudnn filter descriptor: CUDNN_STATUS_BAD_PARAM $ cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2Įdit: In later versions this might be the following (credits to Aris) $ cat /usr/local/cuda/include/cudnn_version.h | grep CUDNN_MAJOR -A 2 $ sudo chmod a+r /usr/local/cuda/lib64/libcudnn* $ sudo cp lib64/libcudnn* /usr/local/cuda/lib64 $ sudo cp include/cudnn.h /usr/local/cuda/include Step 3: Copy the files: $ cd folder/extracted/contents For most people, it will be /usr/local/cuda/. Step 2: Check where your cuda installation is. You might need nvcc -version to get your cuda version. Step 1: Register an nvidia developer account and download cudnn here (about 80 MB). Hence to check if CuDNN is installed (and which version you have), you only need to check those files. The installation of CuDNN is just copying some files.
