Note: ndisk64 had to be radically hacked about and features disabled to get it to compile so I would consider this different source code - don't expect all the options in the AIX version to be available. Linux for computers that use the POWER processor tools:. Note: The command-line options maybe different. Do not ask for support for the AIX 5 version. Compiled on AIX 6 TL7 SP3 runs fine on any later version and AIX 7.1 TL2 onwards. These files contains all the binary command files and scripts.

Hammers or touches memory - complied 64 bit so it has access large memory (many GBs) Uses the Modular IO AIX Expansion pack library must be installed (experimental not currently available) Hammers the disks compiled for large files so it can access large files (many GBs) Hammers the CPUs (can be slowed down to use a percentage) With a 20 line shell script and these tools, I don't have to spend a week of setup time.
For example, I run a Performance Tuning Expert Class and need to quick setup many different workloads and problems to be solved. Learn performance monitoring and tuning. Prove performance of machine upgrades or alternative disk configurations. Soak testing = check a new machine/disk to remove early life failures. This is a great way to ensure your system is working up to spec. You can use this to monitor the CPU, memory, I/O bandwidth, and GPU utilization of your system as well as the CPU and GPU temperatures. I like to use tmux to split my terminal and have htop, sudo iotop, watch sudo sensors, and watch nvidia-smi running simultaneously. gpu_burn 60 # will run gpu_burn for 60 seconds Monitor with htop, nvidia-smi, and sensors. #Linux cpu stress test script install#
Stress -cpu `nproc` -vm `nproc` -vm-bytes 1GB -io `nproc` -hdd `nproc` -hdd-bytes 1GB -timeout 60s Install and run gpu-burn git clone
# `nproc` workers writing to disk (write / unlink) # `nproc` Virtual Memory workers (malloc / free)
# Run a stress test with `nproc` CPU workers (sqrt) sudo apt-get install -y stress htop iotop lm-sensors
On Ubuntu, you can install stress, htop, and iotop via apt-get.
#Linux cpu stress test script drivers#
This article assumes you have the proper GPU drivers in place, check out Lambda Stack if you need to install CUDA, CuDNN, and the NVIDIA drivers. The easiest way to make your own monitoring tool with the output of a script is with the watch command. To stress test a system for simultaneous GPU and CPU loads, we'll use two stress tools: stress and gpu_burn, and three monitoring tools: htop, iotop and nvidia-smi. Often times you'll want to put a system through the paces after it's been set up. This stress test is running on a Lambda GPU Cloud 4x GPU instance. CPU, GPU, and I/O utilization monitoring using tmux, htop, iotop, and nvidia-smi.
