PlaneZip: Lossless Bit-Plane Compression of Training Activations Offloaded over PCIe

Training under a device-memory budget relies on tensor rematerialization: an evicted activation is either swapped to host memory or dropped and recomputed. Because GPU compute has outgrown PCIe bandwidth, cost-model planners such as MegTaiChi, which charge a swap its full transfer time, almost never swap, and swaps tha...

A Point-source Catalogue from Direction-dependent Calibrated 21CMA Images

We present a deep low-frequency radio point-source catalogue centred on the North Celestial Pole (NCP) and extending 5○ in radius, derived from a single 24-h observation with the 21 CentiMeter Array (21CMA). Covering 75–175 MHz, the catalogue characterises extragalactic foreground point sources for Epoch of Reionizat...
