Abstract: A method for performing opportunistic write-back discard of single-use vector register values. The method includes executing instructions of a GPU in a default mode, detecting a beginning of a single-use section that includes instructions that produce single-use vector register values, and executing instructions in a single-use mode. The method includes discarding the write-back of a single-use vector register value if the single-use value gets forwarded either via a bypass path or via register file cache. The method includes inserting hint instructions into an executable program code that demarcates single-use sections. A system includes a microprocessor to execute instructions in the default mode. The microprocessor detects a beginning and an ending of a single-use section that includes instructions that produce single-use vector register values.

Abstract: A service provider may receive item price information and/or point of sale (POS) transaction information from a plurality of merchant devices associated with a plurality of merchants. The service provider may categorize the plurality of merchants according to the types of items offered by the respective merchants, and may further categorize the merchants according to the locations at which they conduct business. The service provider may subsequently determine a price recommendation or other pricing information for a particular item offered by a particular merchant. A merchant device of the particular merchant may present the pricing information in a user interface that enables the merchant to view projected sales at various different price points. Further, the merchant may be able to specify one or more factors used for determining the recommend price, such as a desired business model, a desired clientele, a desired profit margin, or the like.

Abstract: A method of managing a multi-party cardless payment transaction includes receiving, at a service provider, a request for creating a data structure for tracking user expenses associated with an event; generating the data structure, wherein the data structure is stored in association with a database of the service provider; associating two or more user accounts with the data structure; receiving, via an application executing on at least one user device associated with a user account, expense data associated with the event; determining, for each user account, a portion of the expense data to be allocated to each user account; determining, based at least in part on the portion of the expense data to be allocated to each user account, an amount owed by each user; and causing at least one amount to be presented on the application to facilitate payment for at least the portion of the expense data.

Abstract: A method of managing a cardless payment transaction between a customer and a merchant includes receiving, from a device of a customer, an indication of consent to join the customer to a cardless payment transaction, where the cardless payment transaction is between one or more other customers and the merchant; receiving from the customer device, location data indicating that the customer device is in proximity with the merchant; joining the customer with the cardless payment transaction between the one or more other customers and the merchant; receiving transaction data between the merchant and each customer; and submitting, for each customer associated with the cardless payment transaction, a transaction between the merchant and the customer to a financial service for authorization.

Abstract: In some examples, a computing device may receive, from a first user device, a communication indicating a request to create a combined order for items offered by one or more merchants. For example, the combined order may enable a plurality of users to independently purchase individual ones of the items from the one or more merchants. The combined order may be created having an initial condition and may be accessible by the plurality of users for adding items to the combined order. At least one selection of a respective item may be received from each user of the plurality of users. For instance, each selection may change the condition of the combined order. In addition, the computing device may process the items added to the combined order as a single order to perform at least one action.

Abstract: A particular item may be categorized based on delivery times of the particular item. In some instances, the particular item may be ranked across multiple merchants that are offering the particular item for acquisition. The ranking may be based on an estimated amount of delivery time to deliver the particular item, for the individual merchants, to a current location of a user. The estimated amount of delivery time may be based on a preparation time for the respective merchant to prepare the particular item, a courier time for a courier to transport the particular item to the current location of the user, and so on. Information regarding the ranking may be displayed or otherwise output to enable the user to identify and order the particular item from a merchant that satisfies the user's needs.

Abstract: In some examples, a first device of a first buyer may receive a selection of a first item offered by a selected merchant. The first device may determine whether any second devices are within a threshold distance of the first device. Based on a second device being within the threshold distance, the first device may send, to the second device, a communication for creating a combined order. Receipt of the communication may cause the second device to present, to a second buyer, an interface for creating a combined order. The second buyer may use the second device to select a second item to order from the merchant. At least one of the first device or the second device may send combined order information to a service computing device, which may send the combined order to the merchant and schedule a courier to deliver the ordered items to the buyers.

Abstract: Item-level information of a particular item may be processed to categorize the particular item. In some instances, the particular item may be ranked across multiple merchants that are offering the particular item for acquisition. The ranking may be based on the item-level information that relates to an attribute of the particular item for the individual merchants. For example, the item-level information may include a cost of the particular item at a merchant, a rating of the particular item for a merchant, a number of calories of the particular item for a merchant, and so on. Information regarding the ranking may be displayed or otherwise output to enable the user to identify and order the particular item from a merchant that satisfies the user's needs.

Abstract: In some examples, a first device associated with a first buyer may present information related to a plurality of merchants offering items for delivery. The first device may receive, as a first order, a selection of a first item offered by a selected merchant. The first device may determine that a second device is within a threshold distance of the first device, and may send, to the second device, a communication for creating a combined order, such as for dividing a delivery fee associated with the order. A second buyer may use the second device to select a second item to order from the selected merchant. At least one of the first device or the second device may send order information to a service computing device, which may send the combined order to the first merchant and schedule a courier to deliver the order to the buyers.
