@ElbaSatGuy @SAPSAN_CYBERSEC Interesting on my hydrasdr-fft project I'm getting 2.54 ms (faster than FFTW 3.3.10 ...) for a 1M FFT using AVX-512 on 1 core on a Ryzen9 7950X3D.

@SAPSAN_CYBERSEC Latency on RTX 3050ti: 4M FFT: ~40ms (25 fps) 64M FFT: ~500ms (2 fps) USB not the bottleneck - HackRF delivers 160 MB/s, GPU can process 10x that rate. The limit is FFT compute time + memory BW. Persistent GPU allocations mean zero malloc overhead.

Working on my CUDA FFT code GPS L1 spectrum at 1575.42 MHz showing GPS satellites with distinct Doppler offsets. 4.2M point FFT achieving 4.77 Hz frequency resolution. Captured with HackRF One / RTX3050 GPU. 4M FFT size

libhydrasdr v1.1.0 major upgrade for HydraSDR RFOne ! Hardware-agnostic API with automatic DDC decimation: sample rates from 78.1 kHz to 10 MHz, HD mode, lock-free streaming & ~2x performance boost. Try it now in SDR++ nightly ! github.com/hydrasdr/SDRPl… github.com/hydrasdr/hydra…

HydraFW v0.12 Released ! New features: - SPI 3-wire (BIDIR) mode support - Read with timeout for all protocols - Timed read for smartcards - CI/CD with GitHub Actions Thanks to all contributors ! github.com/hydrabus/hydra…

@aang254 Courage...

Le conducteur viens de faire une annonce. Terminus musée d'Orsay.

@RERC_SNCF Bonsoir, le SICK 148856 ira-t-il bien jusqu'à à Saint-Quentin ? Tout semble le laisser penser malgré une interruption totale annoncée... J'aimerais juste savoir pour descendre avant de potentiellement me retrouver plus embêté. ( @ACircule )

@luigifcruz @sylvain_azarian It's marketing madness... this ultra expensive NIC and cable is total nonsense...

@bvernoux @sylvain_azarian They publicize using the NIC to stack multiple DGX together. But maybe they realized mid-development this was not a great idea. But it works great for us!

In the next couple of days I’m testing if the DGX Spark is a good development platform for our new GPU signal processing pipeline for the Allen Telescope Array (and others soon!)

@luigifcruz @sylvain_azarian I do not see why they use that expensive ConnectX-7 stuff they could use external 16x PCIe which will be cheaper and faster...

@sylvain_azarian @bvernoux The RTX 5090 lacks RDMA support, and even if it did. To achieve parity with the DGX, you’d also need to invest an extra 2,000 USD in a ConnectX-7 Dual 200G, along with 1,000 USD for other components. This brings the total to 4,500 USD with a much more expensive shipping cost.

@luigifcruz If they removed the 200Gb NIC, it could be significantly cheaper and more appealing. Most frustratingly, it was originally priced at $3K but launched at $4K after being delayed by several months.

@bvernoux I’m aware of the memory bandwidth limitations, and they are irrelevant for this project (we have the Coyote platform (800G NIC, 6TB/s VRAM) for performance). This project is all about the smallest and cheapest form factor desktop ~development~ box with an integrated NIC and GPU.

Been tinkering with a web app to track Starlink DTC satellites using a 4x4 phased array at 1992.5 MHz. Starlink’s fast-moving, numerous satellites are perfect for testing dynamic beamforming. The app calculates orbital positions, picks the most optimal satellite to track, and visualizes it all with polar plots, azimuth/elevation charts, elevation predictions, ground tracks, and a 3D phased array sim.
