Abstract: A cloud-based framework dynamically utilizes a distributed pool of accelerators to parallelize calculations of physical simulation (physics) solver code partitioned across multiple accelerators and compute nodes of one or more virtual data centers in a virtualized computing environment. Multi-level partitioning logic of the framework partitions an input data set of the physics solver code into code groups configured to run on the accelerators using a “hardware agnostic” software layer that abstracts differences in processing architectures to allow targeting of different types of accelerators. A predictive scheduler interacts with the multi-level partitioning logic to locate and predictively reserve the accelerators within the pool, dynamically access and utilize the accelerators when needed, and then promptly release them upon completion of the calculations.

Abstract: Embodiments in the present disclosure include systems and methods related to a high-availability architecture for a cloud-based concurrent-access collaboration platform. The disclosed technology relates to an active data center which includes multiple document server instances that handle user requests for concurrently accessing documents. Multiple document server instances are implemented on a single physical server. This architecture uses an instance assignment manager to assign documents to the document server instances, a primary repository to store backup snapshots of the documents, and a datastore to store all changes made to the documents. The disclosed technology also involves a backup data center that can be swapped with the active data center automatically.

Abstract: An improved gas flow meter which measures the time of travel of a soap film through a fixed volume to compute gas flow rate. A portable meter includes infrared sensors which detect the passing of a soap film, a timing circuit to determine the time of travel between the beginning and end of the fixed volume and a method of blocking the infrared portion of ambient light to allow for use outdoors. The device has a unique method of generating the soap bubble and for breaking the soap bubble at the end of the fixed volume. The unique flow unit, including flow cell and fixed sensors, is calibrated to determine the fixed volume which is stored in a nonvolatile memory location as a part of the flow unit.
