Create a PyIodide package for Andes #109
Comments
I see now that it is already possible to try Andes online here: |
Got it. Right now, Andes runs online in Binder. I was impressed by matpower.app's performance in WebAssembly. Will give it a shot at some later time. |
This is amazing!! With the latest version of ANDES, you create a customized distribution to ANDES source code to skip the code generation. The steps are as follows.
A folder named The inconvenience is that the above steps need to be executed every time after updating ANDES models. Let me know if any thoughts. |
Hi @rwl , I wonder if you could share the build script |
For some reason, I didn't use the CLAPACK package that comes with Pyodide. I have a version that applies these patches: diff -Naur a/BLAS/SRC/xerbla.c b/BLAS/SRC/xerbla.c

'Development Status :: 4 - Beta', It would be interesting to see how FORTRAN to WASM compilation is coming along. Getting ARPACK working and performing SSSA in the browser would be a first! |
Thank you very much for sharing the code. It still looks challenging, but let me try to build it first. |
The code I wrote was mixed into another repository. I separated it out and pushed it here: https://github.com/rwl/andesapp I haven't tried it, but there it a Dockerfile that should build. |
Hey @rwl and @cuihantao , I saw this interesting, and I'm always trying to improve KVXOPT. I will follow this if you need modifications in KVXOPT for better integration with this Pyodide interpreter. |
Hello @sanurielf and @rwl , Sorry that I didn't follow up until now because I didn't even make the docker image to build. A lot internals have changed in Pyodide, and the documentations was being improved. I was later dragged away by some other works... I perhaps work on it again when the semester ends. |
Andes has a complex set of dependencies that potential users might not be willing to install locally. PyIoidide is an exciting new project that could allow Andes to be run within the browser using WebAssembly. Many of the packages that Andes requires have already been ported to PyIodide. If CVXOPT and SymPy were ported it might be possible to create an Andes package:
https://pyodide.readthedocs.io/en/latest/new_packages.html
This would allow users to create and share notebooks online. Andes running in WebAssembly would open the possibility to create a custom GUI such as that made with MATPOWER:
https://matpower.app/
This could, potentially, also be built into an Electron-based desktop application and made available to download by users wishing to work offline or on air-gaped machines.
