CapabilityEvent Name Description Type 1.0 1.1 1.2 1.3branchNumber of branches taken by threads SM Y Y Y Yexecuting a kernel. This event isincremented by one if at least onethread in a warp takes the branch.Note that barrier instructions (__-syncThreads()) also get counted asbranchesdivergent_branch Number of divergent branches within SM Y Y Y Ya warp. This event is incremented byone if at least one thread in a warp diverges(that is, follows a different executionpath) via a data dependent conditionalbranch. The event is incrementedby one at each point of divergencein a warpinstructions Number of instructions executed SM Y Y Y Ywarp_serialize If two addresses of a memory request SM Y Y Y Yfall in the same memory bank, thereis a bank conflict and the access hasto be serialized.
