RISC-V Disclosure Video

Meeting Participants

Was able to install Java and use the runner package, leveraging a shell script, and works good for self hosted runners.
Gitlab runner binary documentation added to the labs doc (notify Jeff)
When having time, will add updates for Teamcity,
Can we host a github runner (self managed), tried source code, but what is provided fetches a precompiled binary that cannot run on RISC-V.

[carl] looking at codeburg’s ci [woodpecker], but it is entirely open source and might be easier to get working

The boards in PLCT Lab is running well, and there have been no
unplanned power outages in the past four weeks; no new developers have
applied for ssh access; waiting for the delivery of Milk-V Megrez, it
is estimated that several units will be online in March for CI
services for the open source community.
The RISC-V Lab built by Nanjing Inchi has currently obtained 70 LicheePi 4A, 5 Unmatched, and some K230. It has started to provide some package building services for the Arch Linux community.
Hefei University of Technology (HFUT) intends to establish a RISC-V Lab in Anhui Province, China. Currently, some RISC-V equipment has been obtained through the RISC-V development board wandering project (of the Jiachen Project), and more than 50 students have started to learn RISC-V.
Known possible issues:

January 27 to February 5 is the Chinese New Year. Some office areas
hosting RISC-V devices may be shut down and will be restored after the
Spring Festival. We are currently confirming which areas of RISC-V
boards can continue to serve.

Brought wormhole PCIe accelerator online as part of the testbed with latest software API. All pretty stable and working well. Thinking about Carl's point about Fortran, we have lots of hardware and compilers etc available, and a list of the most popular HPC applications - some of these (and libraries) already on the testbed, this could be a foundation to explore some of the gaps/limits here
We have also done some work supporting driving wormhole (and grayskull) from Fortran via OpenMP target offload. Demoed this to Tenstorrent a couple of weeks ago, still lots of work to do but demonstrates the concepts.
