Abstract

According to at least one embodiment, a method for writing, by a computing thread, data to a ring buffer is disclosed. The method includes determining whether the ring buffer is full. If the ring buffer is not full, the method further includes: reserving an element of the ring buffer for writing the data, wherein reserving the element includes incrementing a size variable corresponding to a number of stored elements in the ring buffer; reserving a portion of the ring buffer at which the data is to be written; and determining whether a state of the portion of the ring buffer is in change by at least one other computing thread. If the state is not in change, the method further includes: marking the state of the portion of the ring buffer as being in change by the computing thread; and writing the data to the portion of the ring buffer.
