Abstract: A system and method for blocking path detection is provided. A job comprises tasks with at least some of the tasks dependent on other task(s). Each task is assigned to an ownership team. At a particular point in execution of the job, states of tasks of the job are identified. The states include one of three mutually exclusive states: waiting for another task/finished, in progress, and, blocked. When all the tasks with identified states of in progress or blocked are assigned to a particular ownership team, the particular ownership team is identified as on a blocking path. An action can be performed regarding the blocking path, for example, selected in accordance with policy-defined response actions such as generating an incident, escalating an existing incident, and/or sending a notification (e.g., an accumulated time on the blocking path can be calculated for each team with team(s) notified when certain threshold(s) are exceeded).

Abstract: Examples described herein include systems and methods for fuzz testing low-level virtual devices and virtual devices with DMA write functionality. A fuzz tester includes components distributed across a virtual machine and its host system. The fuzz testing components in the virtual machine are implemented as firmware installed in the virtual machine's ROM. These components operate independent of data stored in the virtual machine's RAM and do not require an operating system to be installed on the virtual machine. As a result, any changes made to the virtual machine's RAM during the fuzzing process by low-level virtual devices or virtual devices with DMA write functionality cannot interrupt the fuzz testing or otherwise negatively impact the fuzz tester itself.

Abstract: The present disclosure provides a game server architecture. A gateway server can pull operation data of game servers and write the operation data into a load balancing cluster to balance load of the game servers, avoiding the crash of the game servers due to excessive load of a certain game server. A database cluster uses data identification segments to balance an amount of data by weight. When the amount of data generated by the game servers or a logic server group is too large, the database cluster can be dynamically expanded to meet storage requirements of the larger amount of data. In addition, when data in the database cluster and a consistent-hash-based cache server is accessed, the data is preferentially accessed from the consistent-hash-based cache server, to avoid a problem that each data access is done through the database, which causes a huge pressure on database IO.
