Description:
<jats:p>Today's hardware architectures provide an ever-increasing number of CPU cores that can be used for running concurrent operations. A big challenge is to ensure that these operations are properly synchronized and make efficient use of the available resources. Fellow database researchers have appropriately described this problem as "staring into the abyss" of complexity [12], where reasoning about the interplay of jobs on a thousand cores becomes extremely challenging. In this demonstration, we show how a new tool, JexLog, can help to visually analyze concurrent jobs in system software and how it is used to optimize for modern hardware.</jats:p>
