Communication links, such as peripheral component interconnect express (PCIe) links between two PCIe-compatible devices, can be checked during a boot process to determine whether those links were established and trained successfully. Firmware, such as Basic Input/Output System (BIOS), can be programmed to determine links for which there are PCIe devices, and determine whether those links were established with the correct values for one or more connection parameters (e.g., speed and width). If one or more of these links was not established with the correct parameter values, the BIOS can perform up to a maximum or threshold number of retrain attempts. If those retrain attempts are unsuccessful, the BIOS can attempt up to a maximum or threshold number of reboot attempts. If, after a maximum number of reboot actions, one or more links still have not been established and trained successfully, a remedial action can be taken.

An optimal combination of content items may be determined and served to increase the likelihood of a predefined user interaction. A user can request content which may include an entity (such as a web page, document, advertisement, and the like) that has multiple components through which content items may be provided. For example, a web page may include multiple slots where content items may be displayed on the web page. Each component may be associated with multiple possible content items, resulting in many combinations of layouts for an entity. A content server may determine which layout to provide using a content selection model that is weighted based on a likelihood of groupings of content items resulting in a user interaction that satisfies a success condition (e.g., selecting a hyperlink, selecting a content item, initiating a transaction, etc.).
