00:45:38 <hyc> my C version of librandomx was something like 10% slower because I ripped out the templating. I plan to reintroduce it using cpp macros
00:46:04 <hyc> but yeah, not fond of the code bloat
07:55:34 <sech1> Some power usage testing running 32 threads (7950X @ 4.275 GHz, 0.85V): RandomX v1 is 18222 h/s, 87.8 watts. RandomX v2 (288, +4 for FMUL_R, -4 for IXOR_R) is 18553 h/s, 87.1 watts. Interesting.
07:56:40 <sech1> CFROUND is so slow on Ryzen that v2 can run 12.5% more instructions (and more power hungry FMUL_R), while using less watts
07:57:46 <sech1> Overall power efficiency increase is 288/256*18553/18222*87.8/87.1 = 15.46% (in terms of energy spent per RandomX instruction)
08:01:23 <sech1> v1: 870.5e6 rx instructions/J, v2: 1005.1e6 rx instructions/J
08:02:10 <sech1> v2 achieves > 1 billion RandomX instructions per joule, nice
08:36:05 <sech1> Same test on Ryzen 5 5600X @ 3.6 GHz, 0.88V: v1 is 6449.86 h/s, 46.551 W, v2 is 6611.02 h/s, 46.903 W - this is 14.4% efficiency increase
13:04:01 <paulio_uk> hmm I'm getting 18100h/s on a 7950x 28 threads 5.2ghz 135w RX1
13:04:09 <paulio_uk> totally power inefficient :D
13:05:22 <paulio_uk> avg. 1.2v per core :| no wonder my office space is warm
17:38:27 <hyc> got hold of a USB A to A cable to try to reflash my rk3588 box. but every write command just dies. this thing's flash memory is just toast.
17:39:08 <hyc> I can still read about the first half of memory. that includes the partition table and all the way thru the boot partition
17:39:22 <hyc> everything after that comes back as 0xCC
17:39:51 <hyc> including what should be the recovery image, backup images, and all of the user data partition. oh well
17:41:30 <paulio_uk> ouch. yeah that's not healthy
17:42:24 <paulio_uk> that lychee pi arrived yet?
17:42:37 <hyc> nope, still in transit
17:43:23 <paulio_uk> :( trying to decide between that or the beagleboard ahead. Its payday and I feel like its time for a new toy
17:45:03 <paulio_uk> then trying to decide between a hackrf one or just some rtl-sdr kit
18:18:16 <Inge> risc-v growing :D
18:18:34 <Inge> paulio_uk: got any interesting sdr projects planned?
20:11:49 <paulio_uk> going to start with the local pub/shop watch radios :P then span out - wouldn't mind having a stab at getting some satellite data
20:12:08 <paulio_uk> and maybe have a bit of a sniff on the old pager signals to see whats still active out there :D
21:16:58 <DataHoarder> hackrf one can also transmit, but that's a rabbit hole paulio_uk 
21:17:27 <DataHoarder> you can get 90% of the way there with $15 receiver and some good antennas (outside of that cost)
21:19:33 <Inge> I'd like to play with a bit of LoRa
22:06:54 <sech1> tevador aarch64 JIT is ready: https://github.com/SChernykh/RandomX/tree/v2 - you can take the changes to your PR now

23:02:01 <DataHoarder> fun pictures
23:27:12 <eureka> so, external SODIMMs?
23:27:20 <eureka> CPU confirmed though :D
23:28:36 <eureka> 6 CPU per board, how many boards though?
23:30:35 <eureka> i'm surprised to see socketed SODIMM
23:32:22 <eureka> 3 boards
23:32:30 <eureka> wow, 18 CPUs per machine
