9754 is 128/256 now, so 256/512 for that. That supermicro system is 8-way; it's 4 dual-socket motherboards but they're one system, hooked together by backplane boards. You can price supermicro's complete-system-only

something that might be useful to you for that; you can get m.2 slot network adapters which you could use on (some) ITX boards. there's at least 1 & 10gbe ones available.

I dunno, if your crypto choices were just "the best thing that won't be included in FIPS" you would do pretty well; blake3, chacha20, 25519 sigs & dh...

yup, for comparison, same file as above using all the threads (32) on my system, I get about 45ms with fully parallel permitted b3. It does run into diminishing returns fairly quickly though; unsurprisingly no improvements in perf using hyp

further research suggests that GNU coreutils cksum will use libcrypto in some configurations (though not mine); I expect that both both your commands above are actually using sha-ni

not sure that tool is correct; on my openssl it shows same output as you have there, but not aes-ni which is definitely enabled and functional. ETA: ahh you want to do that on libcrypto: iced-cpuid <...>/libcrypto.so.3: A

this is less precise than the perf numbers as I don't really have a way to measure power directly, but with rerunning the benchmarks above locked to a cpu core, it boosted ~the same level for all 3 commands (about 5.5ghz), so should be

followup to this now with further blake3 improvements, on a faster machine now but with sha extensions vs single-threaded blake3; blake3 is about 2.5x faster than sha256 now. (b3sum 1.5.0 vs openssl 3.0.11). b3sum is about 9x faster than sh

yup. if you are picky about mobo selection, you can also do it all over one fiber thunderbolt cable; I have my desktop rackmounted and could go up to 165ft away for the desk.

you can run it with `--single-instance` (or `-1`) and you only pay (most of) that startup cost once.

another pretty easy optimization is swapping to https://github.com/minio/sha256-simd , particularly if you're on a process with the sha extensions. versus just spawning a goroutine per attempt, it'll likely be

yup. I pay $25/mo happily but would go up to at least $100 without blinking. I do between 1k and 2.5k searches per mo, and also use the summarizer a bit. Compared to DDG (which I was using before), I haven't done a bang to fall ba

I'm curious what your workflow is that not having any disk caching would have acceptable performance.

other than both being electron apps (and admittedly electron was made for atom), Atom and VS Code share no common codebase.

yup, though that means you're wasting that core's compute; something with green threads where language runtime does a cross-core interrupt to submit syscall then continues execing other green threads until it gets a user interrupt

by vluft 3y ago
With cross-core interrupts and user-mode interrupt handlers (as in some new intel cpus), you could even do something without polling (interrupt for submission) where the core user-mode code is running on _never_ context switches (obviously

well, at that point they might as well not implement it, as it will be well and truly useless

I have a 4u, not a 3u, but sliger has one now that should be pretty good. https://www.sliger.com/products/rackmount/3u/cx3151a/ has a riser for doing a modern (heh) sized graphics card.

tripplite has an 18u (SRQ18U) than can do 37" deep; I've had one for a few years and it works well. You'll still here 40mm screamers running at full speed, but it cuts down on noise a lot.

the only available fiber optic thunderbolt cables I'm aware of right now are from corning, and they are thunderbolt 3. I'm running 5120x1440@120hz through it (and a variety of USB); 4k144hz would be about 35% more bandwidth. Corni

fiber optic DP cables are maybe $70 or $80 and work pretty well in my experience. on the pricier side if you have something with TB support, you can do display and USB over that to a fiber optic TB cable (about $400); this is my current set
