Abstract: Systems and methods for reducing latency of probing operations of remotely located linear hash tables are described herein. In an embodiment, a system receives a request to perform a probing operation on a remotely located linear hash table based on a key value. Prior to performing the probing operation, the system dynamically predicts a number of slots for a single read of the linear hash table to minimize total cost for an average probing operation. The system determines a hash value based on the key value and determines a slot of the linear hash table to which the hash value corresponds. After predicting the number of slots, the system issues an RDMA request to perform a read of the predicted number of slots from the linear hash table starting at the slot to which the hash value corresponds.

Abstract: Techniques are described for pooling data originating from different entities into a data pool managed by a data pool management system for performing accurate and resource-efficient statistical and other data operations by entities. Techniques further include maintaining rule sets that govern access to the data sets of the data pool. The DPMS uses the rule sets to determine whether a particular data set, on which a particular operation is requested to be performed, qualifies as authorized data for the requesting entity. In an embodiment, the DPMS determines, based on one rule set, that the particular data set does not qualify as authorized data for the particular operation. The DPMS further determines that based on another rule set the particular data set does qualify as authorized data for the particular operation. Based on determining that authorizing rule set overrides the non-authorizing rule set, DPMS proceeds to performing the particular operation using the particular data set.

Abstract: A processing device such as a server implementing smart building agent functionality is located on an external network and is configured to communicate with a BAS located on a building's internal network. Communication between the processing device and the BAS occurs over a first communications channel. The processing device can be configured to receive sensor data from various sensors that might otherwise not be supported by the existing BAS. Communication between the sensors and the processing device occurs over a second communications channel different from the first communications channel. The processing device can generate control commands based on the received sensor data that provide instructions to the BAS for adjusting an operation parameter for one or more of the building systems and/or equipment. This control command can be sent to the BAS through the first communications channel.

Abstract: Techniques are described for transaction-based read and write operations in a distributed system. In an embodiment, an authorization protocol overlaid onto a transaction to control access to each of the data pools. Using the techniques described herein, the DTRS provides authorization mechanism to ensure that the entity, which hosts the data pool, may only access the data set from an originating entity based at least upon the access rules of the originating entity set for the data set. Additionally, the DTRS's read/write transactions keep the data pools of the DTRS in synch with each other, so each data pool stores the same data sets as another data pool of the DTRS. When a data integrity service of an entity generates a new data entry from a user transaction with a client application, a new write request is generated for the DTRS to which the data integrity service belongs.
