Abstract: Core-aware caching systems and methods for non-inclusive non-exclusive shared caching based on core sharing behaviors of the data and/or instructions. In one implementation, the caching between a shared cache level and a core specific cache level can be based on physical page number (PPN) and core identifier sets for previous accesses to the respective physical page numbers. In another implementation, the caching between a shared cache level and a core specific cache level can be based on physical page number and core valid bit vector sets for previous accesses to the respective physical page numbers by each of the plurality of cores.

Abstract: Neural network (NN) model training techniques can include computing activations in a forward pass using a sparse weight matrix that is transpose invariant. The neural network (NN) model training techniques can further include computing activation gradients and weight gradients in a backward pass using the sparse weight matrix.

Abstract: The invention relates to a material and its method for rapidly eluting ammonium ions and soluble metal cations in an ionic rare earth ore leaching site, which comprises the following steps: 1) Ferrous sulfate is dissolved in water as an eluant; 2) Take the soil sample from the closed leaching site of ionic rare earth ore to make an eluting column, use the above-mentioned eluent to elute, more than 95% water-soluble and exchangeable ammonium ions in the soil sample are eluted, while more than 90% of the residual rare earths in the soil sample are exchanged into the eluent, which can quickly achieve the purpose of eluting ammonium ions in the leaching site and recovering the residual rare earths, and is beneficial to the soil remediation for the leaching site.

Abstract: Movable thick dehydration device and method for eluent sediment from medium- and low-concentration ammonia nitrogen are provided. The device integrates the existing eluent preparing mechanism, a transferring mechanism, pumping mechanisms, a transport vehicle, an automatic controlling system, an eluent collecting pool, primary and secondary sedimentation pools, and primary and secondary processing units. After post-treatment and recovery of eluent waste from rare earth mines, ammonia nitrogen and rare earth heavy metals in the eluent of rare earth mines can be recovered and disposed, and 90% of ammonia nitrogen and over 95% of rare earth in the eluent can be recycled. The device is movable and automated, and therefore suitable for environmental treatment of closed rare earth mines with residual ammonia nitrogen. Meanwhile, it is beneficial to reduce investment costs of capital construction, disposal site restoration of environmental treatment of rare earth mines with residual ammonia nitrogen.
