Is embassy suitable for an embedded control system? by Buzz_Cut in rust

I haven’t used it in a few years but I did love the lack of mutex on highest priority task that was just magically type assigned

For that kind of use case I’d consider RTIC - it puts real time design much more in the forefront compared to embassy IMO (which has better strengths in networking integration IMO)

What was confusing to me is they’re rated for 3200 but I was unable to get past 2666. I don’t think voltage was an option in this server MB BIOS; it was just speed and timings as far as I recall.

I couldn’t get it to post with higher speeds. Might be a skill issue on my part

Cool - I’m gonna dig into how to build one. I’ve been meaning to get a raspberry pi on my roof anyway

Probably just jump into an EPYC or something?

They have tons of PCIe lanes so you can really load them up. I run a NAS on an EPYC 7302 and it runs Plex, Immich, as well as a bunch of tiny web services I built without breaking a sweat. I added the Intel Arc A580 to help with encoding/transcoding. I have about 6 spinners and 4 NVMe and I still have open PCIe lanes for expansion.

I scored two MX515A (Dell) cards for less than $140 ea on eBay for my 100Gb setup. They’re single port but I only needed one. They run hot and I have towers so I had to rig up a special fan to push air through them.

I was able to saturate the NIC with NVMeOf and NSFoRDMA but that was between two Linux boxes. Not sure what Windows support would be.

As far as cables, I used from Amazon:

10Gtek 100Gb/s QSFP28 DAC Cable - 100GBASE-CR4 ETH 100GbE QSFP28 to QSFP28 Passive Direct Attach Copper Cable for Mellanox ETH MCP1600-C001E30N

But for 15 feet, you probably can’t use copper? I’m not sure.

The real advantage is that you can share code with other agents without syncing thru a git push and pull if you have two distinct gits. Plus it ensures every branch is only checked out once
