# 7.51. CUpti_ActivityJit2

struct CUpti_ActivityJit2

  The activity record for JIT operations.

  This activity represents the JIT operations (compile, load, store) of a CUmodule from the Compute Cache. Gives the exact hashed path of where the cached module is loaded from, or where the module will be stored after Just-In-Time (JIT) compilation.

  Public Members

  CUpti_ActivityKind kind

    The activity record kind must be CUPTI_ACTIVITY_KIND_JIT.

  CUpti_ActivityJitEntryType jitEntryType

    The JIT entry type.

  CUpti_ActivityJitOperationType jitOperationType

    The JIT operation type.

  uint32_t deviceId

    The device ID.

  uint64_t start

    The start timestamp for the JIT operation, in ns.

    A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the JIT operation.

  uint64_t end

    The end timestamp for the JIT operation, in ns.

    A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the JIT operation.

  uint32_t correlationId

    The correlation ID of the JIT operation to which records belong to.

    Each JIT operation is assigned a unique correlation ID that is identical to the correlation ID in the driver or runtime API activity record that launched the JIT operation.

  uint32_t padding

    Internal use.

  uint64_t jitOperationCorrelationId

    The correlation ID to correlate JIT compilation, load and store operations.

    Each JIT compilation unit is assigned a unique correlation ID at the time of the JIT compilation. This correlation id can be used to find the matching JIT cache load/store records.

  uint64_t cacheSize

    The size of compute cache.

  const char *cachePath

    The path where the fat binary is cached.

  uint32_t processId

    The ID of the process where the JIT operation is executing.

  uint32_t threadId

    The ID of the thread where the JIT operation is executing.
