A Tool for Performance Analysis of GPU-accelerated Applications KerenZhouandJohnMellor-Crummey DepartmentofComputerScience,RiceUniversity Abstract Apr 15, 2013 · Can anyone explain Gpu usage to me? When I play BF3, my CPU (i5 2500k) sits around 60-70% usage and GPU is at 99% usage, which is good. But now i'm playing F1-2012 and CPU usage is at 75-85% while GPU usage only at 65-75% usage. Why doesn't this game run at 99% usage? Isn't that ideal? Wouldn't...

Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. GPU kernel latencies of the TensorFlow’s and MXNet’s ResNets are about the same, MXNet has a much larger non-GPU latency com-pared to TensorFlow for batch size 1. ResNet_v1_50, for example, has a non-GPU latency of 4.44ms (55.1% of the total online latency) for MXNet whereas it is only 2.18ms for TensorFlow (35.3% of the total). A GPU computation that requires 39.1% of the time for kernel main_24_gpu. A helpful feature of the PGI OpenACC compiler is that it intelligently labels the kernel with the routine name and line number to make these timelines intelligible. GPUs and Accelerators at CHPC.

Analysis of Hardware Usage Of Shuffle Instruction Based Performance Optimization in the Blinds-II Image Quality Assessment Algorithm by Ameya Wadekar A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science Approved June 2017 by the Graduate Supervisory Committee: Sohum Sohoni, Chair Daniel Aukes It allows software developers to use a CUDA-enabled graphics processing unit (GPU) for general purpose processing – an approach known as GPGPU. The CUDA platform is a software layer that gives direct access to the GPU’s virtual instruction set and parallel computational elements, for the execution of compute kernels.
GPU Programming and CUDA. ... Usage of cuda-gdb is similar to gdb. ... Kernels of one cuda version will not execute with NVVP of another version.

Note: Citations are based on reference standards. However, formatting rules can vary widely between applications and fields of interest or study. The specific requirements or preferences of your reviewing publisher, classroom teacher, institution or organization should be applied. This was done independently of VSync. But somewhere shortly after that, they made a change to the driver (for reasons I'm not sure) and the FPS cap was removed from GSync. Its primary, and, really, only reason for existing is to keep the display and GPU in sync when the GPU can't hit the display's max refresh.

For convenience, LC provides the -gpu commands, which set the option -fopenmp for OpenMP and -fopenmp-targets=nvptx64-nvidia-cuda for GPU offloading. Users can do this themselves without using the -gpu commands. However, use of LC's -gpu commands is recommended at this time since the native Clang flags are verbose and subject to change ...

) and single precision calculations run efficiently on the cheap consumer NVidia Geforce GPUs. Such GPUs can be installed in most computers, given enough power supply. Using various GPUs and profiling with nvvp we found that our calculations are memory bound, i.e. the execution speed scales with the memory bandwidth of the GPU. Dec 24, 2014 · We compare our cuFFT convolution results against NVIDIA’s cuDNN 1.0 library (Chetlur et al. ), which contains one of the fastest, general purpose convolution methods for the GPU, using matrix unrolling. It has decent performance for many problem sizes thanks to heavy autotuning of cuBLAS codes for different problems. Memory Utilization vs Compute Utilization Four possible combinations: PERFORMANCE LIMITER CATEGORIES Comp Mem Compute Bound Comp Mem Bandwidth Bound Comp Mem Latency Bound Comp Mem Compute and Bandwidth Bound 60% It support various analysis including CPU usage, memory usage, memory leaks, thread synchronisation and exception profiling. YourKit can be used for high level analysis (to see application behaviour) or low-level detail (to pinpoint performance issues). It provides high level monitoring of web, I/O and database activity.

l1_local_load_hit: Number of cache lines that hit in L1 cache for local memory load accesses. In case of perfect coalescing this increments by 1, 2, and 4 for 32, 64 and 128 bit accesses by a warp respectively. l1_local_load_miss: Number of cache lines that miss in L1 cache for local memory load accesses. Feb 06, 2019 · It means that you don’t have data to process on GPU. One reason can be IO as Tony Petrov wrote. Two other reasons can be: 1. complex preprocessing. The program is spending too much time on CPU preparing the data.

Another helpful flag is --output-profile which generates a file detailing the profile, which can be later imported back into nvprof, or perhaps nvvp. NVIDIA Visual Profiler (NVVP) is a profiler with a graphical user interface. It is included in the CUDA Toolkit, and it does not require any code modification. CUDA Profiling Tools Interface (CUPTI) is a C library that allows access to hardware counters of the GPU. It also allows the user to attach user-defined

Hello, do you know how to see GPU utilization with nvvp? I only see the duration of a function. But I want to also see the percentage of GPU utilization during a function.  

Part 1: Load-Balanced, Strong-Scaling Task-Based Parallelism on GPUs July 9, 2014 by Rob Farber Leave a Comment Achieve a 7.4x speedup with 8 GPUs over the performance of a single GPU through the use of task-based parallelism and concurrent kernels!

CUDA programming is all about performance. So through out this course you will learn multiple optimization techniques and how to use those to implement algorithms. Also we will extensively discuss profiling techniques and some of the tools including nvprof, nvvp, CUDA Memcheck, CUDA-GDB tools in the CUDA toolkit.
GPU Value - For Fermi and Kepler architectures, this is the counter result in respect to the whole GPU. In other words, this is an estimated value for the GPU if the experiment was unable to collect from all units. This may happen if the coverage is not 100%, or if multiple passes were needed to collect from all units.

./nvprof -m tensor_precision_fu_utilization ./app_name. This returns the utilization level of the multiprocessor function units executing Tensor cores instructions on a scale of 0 to 10. Any kernel showing a non-zero value is using Tensor cores. Note that profiling of metric and event is only supported up to the Volta architecture through Nvprof. GPU Profling For the CPU version of the code we have VTune to profile, as well as our tasking plots. However for the GPU version of the code we need different software to profile the MegaKernel ™ and improve its performance. Getting nvvp The GUI profiling tool can be downloaded here. Tracking memory usage can be as important as execution performance. Usually, the memory will be more constrained on the device than on the host. To keep track of device memory, the recommended mechanism is to create a simple custom GPU allocator that internally keeps some statistics then uses the regular CUDA memory allocation Oct 15, 2015 · Hardware background knowledge will also be covered to help give a better understanding of the instruction latency, occupancy, hardware utilization, memory bandwidth, etc.

Dec 22, 2017 · nvprof-tools - Python tools for NVIDIA Profiler. Tools to help working with nvprof SQLite files, specifically for profiling scripts to train deep learning models. The files can be big and thus slow to scp and work with in NVVP. This tool is aimed in extracting the small bits of important information and make profiling in NVVP faster.

Review the nvidia-smi usage summary. What to do if GPU utilisation = 0% when running TUFLOW HPC (when using the GPU Module) Windows 10 includes a Quick Edit mode option in the DOS window that can artificially pause TUFLOW simulations. Usage. For usage, please follow the instructions in the user guide, which you can find in doc/sassi-user-guide.pdf. Additionally, ptxas -h lists SASSI's supported options.

Mat, *I* thought the GPU-load is low, because there's to much CPU-Code between the GPU-Code. *You* suggest to think about kernels, gang, etc. OK. Problably you are right, but I'd really like to know how much time is spent on CPU/GPU. I worked from time to time with PGI_ACC_TIME. So far I never looked at "how many gangs are being scheduled".
