Abstract: Techniques are provided for automated sharing of remote devices by multiple users using a file system. One method comprises maintaining public keys for source devices associated with users; configuring a primary target device to provide a file system that comprises: (i) a user-specific directory for each of the users, and (ii) a global directory accessible by the users, wherein the user-specific directory for a given user comprises the public key for the source devices associated with the given user; and configuring a secondary target device to provide a copy of the file system, wherein updates to the file system are provided to the secondary target device, and wherein the given user accesses the primary and/or the secondary target device, using a particular source device, based on an evaluation of the public key for the particular source device obtained from the user-specific directory for the given user.

Abstract: Approximating energy use of software executing on virtual machines is presented herein. A system determines a pair of energy consumption baselines of a host computing device representing respective energy being utilized by the host computing device; determines, at a sampling time within a job execution period during which a job has been executing on a virtual machine (VM) of the host computing device, an energy consumption of the host computing device; and based on the pair of energy consumption baselines and the energy consumption of the host computing device, and further based on respective estimated portions of processing resources of a central processing unit of the host computing device being utilized, at the sampling time, by the VM and by the job within the VM, determines an approximate amount of energy use of the job that has executed on the VM.

Abstract: An apparatus in one embodiment comprises at least one processing device that includes a processor coupled to a memory, with the at least one processing device being configured to provide an authentication service for sharing access credentials of a protected resource among multiple users. The at least one processing device in providing the authentication service for sharing the access credentials is further configured to obtain the access credentials at least in part from a first one of the users, to automatically provide the access credentials to at least one additional one of the users responsive to authentication of the at least one additional user and satisfaction of one or more specified distribution conditions, and to automatically modify the access credentials responsive to satisfaction of one or more specified revocation conditions. The protected resource may comprise, for example, a user account of a website.
