Abstract: Hardware acceleration of task dependency management in parallel computing, wherein solutions are proposed for hardware-based dependency management to support nested tasks, resolve system deadlocks as a result of memory full conditions in the dedicated hardware memory and synergetic operation of software runtime and hardware acceleration to solve otherwise unsolvable deadlocks when nested tasks are processed. Buffered asynchronous communication of larger data exchange are introduced, requiring less support from multi-core processor elements as opposed to standard access through the multi-core processor elements. A hardware acceleration processor may be implemented in the same silicon die as the multi-core processor for achieving gains in performance, fabrication cost reduction and energy consumption saving during operation.

Abstract: The techniques disclosed herein provide dynamic permissions for controlling messages directed to a presenter of a communication system. For example, during a presentation of an online meeting, a system may selectively permit private messages to be sent to a presenter from designated participants. The private messages sent from the designated participants are displayed to the presenter in a manner that does not allow the other participants to see the messages. For instance, if the presenter is sharing a screen from a computer, the system can determine a set of permitted users allowed to send messages to the presenter. The system configures permissions to cause the messages to be displayed in a manner that allows the presenter to view the messages along with their presentation content, while restricting or suppressing the display of the messages to other non-permitted users. The system restricts the non-permitted users from sending messages to the presenter.

Abstract: Aspects relate to techniques for using read-only volume replicas in a distributed computing environment to enable over-subscription on server performance. In order to provide a good customer experience, the I/O handling replicas of a volume are typically reserved at a high percentage of the customer's desired performance. A read-only replica of the volume does not serve user I/O, and can therefore be reserved at a much lower percentage of desired performance. Particularly, as the number of read-only replicas increases, the performance reservation can be lowered due to the statistical likelihood that the server(s) hosting at least one read-only replica will have sufficient performance to support the desired reads during new volume creation (even though that performance has not been fully reserved). Aspects relate to techniques for selecting among read-only replicas to serve reads during creation of a new volume copy.
