The graph seemed to be of estimated development years. If you accumulate an in place FS, dm, mdraid, LVM and all assorted userland tools I think that ZFS is probably less code complexity. There is some ideological complexity, namely the AR

Your final line is 100% correct but all your supporting details are not. HPC is generally a "softball" workload because the code is going to be more sympathetic to the hardware than many other computer usages. Processes will batc

https://en.wikipedia.org/wiki/Linus%27s_Law The results of "many eyes" seems to be basically moot (i.e. certainly not a 10x magnitude and more likely well below 2x) in the face of the cultural mores of a proj

Mainly because I have been trying to sign them up with similar reasoning. A lot of people spent foolish amounts of capital on arm64 enablement, I'm glad FreeBSD has it for embeded stuff, but the server-class silicon just sucks compare

The page is awkwardly sexist.. but that would be a pretty close to an awesome integrated numpad design for programmers.

Your other comment about NFLX makes you seem suspiciously and hilariously like a sock-puppet account so I can't actually be candid on that now. For getting vendors to do things, it helps that I have a 8-figure HW spend. I'm not G

DCTCP is designed for.. data center networks. You have first party control and can ensure ECN works end to end on your equipment. BBR is designed for the "hostile internet" where you can't rely on ECN marking, and basically

Looking around the Mill Computing, Inc website, this feels like an (accidental?) sweat equity scam. I realize that is a very loaded charge, but this is NOT how real companies are run: "In the beginning we were a sweat equity organizat

The kernel ABI is stable between major version numbers. It is never intentionally broken between majors. More importantly, the kernel APIs are very stable, which seems to be intentionally broken on Linux regularly. Userland ABI is much mo

From a business perspective, I think it's easier to pick up *BSD talent. Although the pool is smaller, the pool is more talent dense. If you can afford to not care about the kernel (serverless etc) Linux is fine, if you have to care

I love ZFS and use it as much as possible. But we make heavy use of UFS at $work because sendfile and fail in place. I'm in the market for a flash filesystem for this use case. I doubt APFS has that all figured out, but it might be

Dang, no APFS. Was hoping to gauge how portable it'd be to *BSD.

Yeah I don't see FreeBSD entering the HPC market ever, except maybe for I/O nodes. Nothing explicitly wrong with that, you have to choose battles.

I'll probably get some scowls for this but Mellanox sales and support has rubbed me the wrong way numerous times. I'm trying to mend that at the moment for my company. Chelsio has a more technically interesting product to me so f

There is a port of the FreeBSD network stack called libuinet so that's not an unsolved problem, but it would need a bit more care and feeding. There are other issues like.. you need to fetch content off disks, and then you need to mov

Line-rating 100g DC networking is close to plug and play today with Chelsio's zero copy stuff inside a LAN/MAN. Single digit CPU util. The needs of long haul TCP are a bit harder. Check out the TCP RACK RFC and packet pacing to

I find that subject line completely terrifying. Please use a small trusted compute base, hopefully with rigorous auditing and attempts at formal modeling, for safety critical systems. The Linux kernel development process is not suitable f

I'm starting to test it in co-processor mode. The main limit is.. Intel is dragging their feet on PCIe bandwidth (probably to curtail GPGPU a bit), and you need a lot of BW for co-processor up and down and then back out the pipe. But

I use a 2x12 core Xeon v2, 128GB RAM. I work full time on OS kernels, mainly FreeBSD. It helps a ton for building kernels, world, packages, and running lots of VMs. Thinking of doing the Talos II as the next step. Imagine doing web dev i
