Abstract: The disclosure herein describes platform-level checkpointing for deep learning (DL) jobs. The checkpointing is performed through capturing two kinds of state data: (i) GPU state (device state), and (ii) CPU state (host state). The GPU state includes GPU data (e.g., model parameters, optimizer state, etc.) that is located in the GPU and GPU context (e.g., the default stream in GPU, various handles created by the libraries such as DNN, Blas, etc.). Only a fraction of the GPU memory is copied because the checkpointing is done in a domain-aware manner. The “active” memory contains useful data like model parameters. To be able to capture the useful data, memory management is controlled to identify which parts of the memory are active. Also, to restore the destination GPU to the same context/state, a mechanism is used to capture such state-changing events on an original GPU and replayed on a destination GPU.

Abstract: An identification document has an activatable security feature, the activatable security feature has a first antenna part and a second antenna part arranged such that a gap is formed between them. The security feature further has a patch connected to the first antenna part and the second antenna part such that it bridges the gap, the patch being formed of a material having conductive properties which are changeable from low-conductive to high-conductive such that a conductive path is provided between the first antenna part and the second antenna part after energy has been applied to the patch, such as by laser irradiation. The security feature further has an electrical device such as an RFID chip connected to the first antenna part and/or the second antenna part.

Abstract: A User configures the option in his/her UE to deliver the SMS via Operator's application client installed on UE. This configuration will be saved in the UDM as an option opted by UE. SMS-GMSC receives the “SMS delivery flag (indicating alternate delivery mechanism is enabled)” from UDM in response to the “Send Routing Infor for SM” message. If the traditional SMS delivery over mobile operator network fails (e.g. no connectivity), then SMS-GMSC will trigger NEF to re-attempt the SMS delivery to UE. (NEF can be an optional network function as Application function is trusted one and hosted in Operator's network). NEF sends the SMS to Application Function (Mobile Network Operator's Serer) which encrypts the SMS payload and delivers the SMS to operator's application client e.g. Mobile Network Operator App installed on UE over the alternative data connectivity (Ex. Wi-Fi Broadband).

Abstract: A method performed by first User Equipment (UE) for applying policy enforcement for data traffic in an UL data session is provided. The UL data session is from the first UE to a data network via a Radio Access Network (RAN) a Core Network (CN) and a first Network Slice (NS) in a radio communications network. The UE obtains first information from a CN node in the CN. Upon establishing the UL data session, the UE measures data traffic performance and radio conditions in the RAN. The UE predicts available resources for transmitting data from the first UE towards the data network via the RAN, the CN, and the first NS. The prediction is based on the obtained first information, the measured data traffic performance and radio conditions in the RAN. The UE then applies policy enforcement for the data traffic in the UL data session based on the prediction.
