Reducing contentions between processes or tasks that are trying to access shared resources is described herein. According to embodiments of the invention, a method of writing a set of data associated with a task to a memory resource is provided. The method includes calculating the amount of memory required to write said data to the memory resource and updating an expected end marker to reflect the amount of memory required to write the data to the memory resource. A flag is then set to an incomplete state, and the data is written to the memory resource. The flag can be set to a complete state and an end marker is updated. The end marker indicates the end of the data stored in the memory resource.
