When you install Miniconda3 or Anaconda3 on Windows it adds a PowerShell shortcut that has the necessary environment setup and initialization for conda. It’s listed in the Windows menu as “Anaconda Powershell Prompt (Anaconda3)”. However, this opens a separate/detached PowerShell instance and it would be nice to have this as an optional shell from Windows Terminal! In this post we will add that functionality as a new shell option in Windows Terminal.
The second new NVIDIA RTX30 series card, the GeForce RTX3090 has been released.
The RTX3090 is loaded with 24GB of memory making it a good replacement for the RTX Titan… at significantly less cost! The performance for Machine Learning and Molecular Dynamics on the RTX3090 is quite good, as expected.
The much anticipated NVIDIA GeForce RTX3080 has been released. How good is it with TensorFlow for machine learning? How about molecular dynamics with NAMD? I’ve got some preliminary numbers for you!
WSL2 offers improved performance over version 1 by providing more direct access to the host hardware drivers. Recent “Insider Dev Channel” builds of Win10 even allows access to the Windows NVIDIA display driver for GPU computing applications for WSL2 Linux applications! The performance improvements with WSL2 are largely because this version is running as a privileged virtual machine on to of MS Hyper-V. This means that at least low level support for the Hyper-V virtualization layer needs to be enabled to use it. In particular, the Windows feature “VirtualMachinePlatform” must be enabled for WSL2. We tested to see if there was any negative application performance impact.
The current JupyterHub version 2.5.1 does not allow user installed extension for JupyterLab when it is being served from JupyterHub. This should be remedied in version 3. However, even when this is “fixed” it is still useful to be able to install extensions globally for all users on a multi-user system. This note will show you how.
WSL on Windows 10 does not (currently) provide a direct way to copy a Linux distribution that was installed from the “Microsoft Store”. The following guide will show you a way to make a working copy of an installed distribution with a new name.
In this note I’ll go through creating self-signed SSL certificates and adding them to a JupyterHub configuration running on a LAN or VPN. This will allow encrypted access to the server using https in a browser.
This is a quick note about setting up a JupyterHub server and JupyterLab using conda with Anaconda Python.
On March 19, 2020 I did a webinar titled,
“AMD Threadripper 3rd Gen HPC Parallel Performance and Scaling ++(Xeon 3265W and EPYC 7742)”
The “++(Xeon 3265W and EPYC 7742)” part of that title was added after we had scheduled the webinar. It made the presentation a lot more interesting than the original Threadripper only title! This is a follow up post with the charts and plots of testing results presented in that webinar.
Is 32-cores enough? I had some testing time again on an AMD Threadripper 32-core 3970x and thought it would be interesting to compare that to the 64-core 3990x. In this post I take a comparative look at parallel performance and scaling for HPL Linpack, Python numpy and the NAMD molecular dynamics program.
