New Project: ispc

[aneshlya]

Please describe the project
ispc is a compiler for a variant of the C programming language, with extensions for single program, multiple data programming. Under the SPMD model, the programmer writes a program that generally appears to be a regular serial program, though the execution model is actually that a number of program instances execute in parallel on the hardware.
It's getting support for ppc64le architecture: ispc/ispc#3735

URL for the project
https://github.com/ispc/ispc

Describe current CI/CD setup
ISPC utilizes Github actions for build/testing (functional and lit testing, examples) and security scans.

Describe the primary use case for the Github Action Runner
ISPC is getting support for Linux ppc64le, enabling compilation for POWER8+ (POWER ISA 3.0) processors. We would like to run functional tests and examples on native ppc64le HW..

Paste a link to the existing actions workflow file(s) or directory
https://github.com/ispc/ispc/tree/main/.github/workflows

How often do you plan on executing the runner?
Every pull request (usually one/day or less) and once during nightly testing.

What is the primary programming language for the project?
C++

Please select desired hardware

• Power 9 (ppc64le)
• IBM Z / LinuxONE (s390x)

It's worthy to point out that Pull Request submitted against this project require Approval from the core team to enable CI run so there is unlikely some random people could abuse CI

We do not have p8 machines to offer but we can run the workflows on power9. You can view our supported images here. If thats ok with you, I can send the link for our app and further instructions to be approved :)

Thanks!
ubuntu-24.04-ppc64le sounds good.
@runlevel5, do you have any preference?

Please install the GitHub App from the following link and select your repository:
🔗 Power Z GHA Runner App

For more details on the onboarding process, please refer to our documentation:
📄 Onboarding Guide

Please let me know in this issue once you have installed the github app on your repo. For security reasons, I will double check it is the correct repo and then approve the repo to use our images. You will not be able to use our images until I approve the repo.

After the repo has been approved, you will be able to use the ubuntu-24.04-ppc64le image your workflow file and all good to go! The onboarding doc linked above will be helpful.

Please note: forks will not be able to use this service since those repos will not be in our allow list.

If there is any questions or concerns, we can discuss those here.

@aneshlya I would much prefer 25.10 as it would have LLVM20 package but having said that it is fine because there are many workarounds.

@mtarsel great thanks for setting us up.
@aneshlya could you please follow up on setting that up on your side? Once done I could update my Pull Request to give that runner a go. Many thanks in advance.

@mtarsel, thanks a lot! I installed the github app to ispc/ispc repo.

The repo has been approved! You can now use our images in your workflow files :) I'll leave this issue open for a couple more weeks in case there is more questions or any issues. Thanks!
