clusterlaunchcontrol.query_cancel Parallel Synchronization and Communication Instructions

clusterlaunchcontrol.query_cancel.is_canceled.pred.b128 pred, try_cancel_response;

Instruction clusterlaunchcontrol.query_cancel can be used to decode opaque response written by instruction clusterlaunchcontrol.try_cancel.

Encoding

PTX is a virtual instruction set. It has no single, stable native binary encoding - the compiler lowers this instruction to different native machine code depending on the selected NVIDIA target architecture (compute capability). This page intentionally shows no bit-diagram; see the target/version requirements below for what governs how this instruction compiles.

Description

Instruction clusterlaunchcontrol.query_cancel can be used to decode opaque response written by instruction clusterlaunchcontrol.try_cancel. After loading response from clusterlaunchcontrol.try_cancel instruction into 16-byte register it can be further queried using clusterlaunchcontrol.query_cancel instruction as follows: clusterlaunchcontrol.query_cancel.is_canceled.pred.b128: If the cluster is canceled successfully, predicate p is set to true; otherwise, it is set to false. If the request succeeded, the instruction clusterlaunchcontrol.query_cancel.get_first_ctaid extracts the CTA id of the first CTA in the canceled cluster. (see the official PTX ISA docs for the full description)

Examples

clusterlaunchcontrol.query_cancel.is_canceled pred.b128 p, handle;

@p clusterlaunchcontrol.query_cancel.get_first_ctaid.v4.b32.b128 {xdim, ydim, zdim, ignr}  handle;

clusterlaunchcontrol.query_cancel.get_first_ctaid::x.b32.b128 reg0, handle;
// (truncated - see the official PTX ISA docs for the full example)
