Class Documentation

class switchml::BypassPPP : public switchml::PrePostProcessor

A class that ignores prepostprocessing completely and just serves as a placeholder.

It is used for debugging and measuring performance without any prepostprocessing. It consists of mostly empty inline functions that will most likely be simply compiled away.

Public Functions

inline BypassPPP(Config &config, WorkerTid worker_tid, Numel ltu_size, Numel batch_num_ltus)

Calls the super class constructor.

Parameters

  • config – [in] A reference to the context’s configuration.

  • worker_tid – [in] The worker thread that this prepostprocessor belongs to.

  • ltu_size – [in] The size in bytes of the logical transmission unit used by the backend.

  • batch_num_ltus – [in] How many LTUs constitute a batch.

~BypassPPP() = default
BypassPPP(BypassPPP const&) = delete
void operator=(BypassPPP const&) = delete
BypassPPP(BypassPPP&&) = default
BypassPPP &operator=(BypassPPP&&) = default
inline virtual uint64_t SetupJobSlice(JobSlice *job_slice) override

Compute the number of LTUs needed.

Parameters

job_slice – [in] A pointer to the job slice currently being worked on by the worker thread.

Returns

uint64_t the number of transmission units that prepostprocessor will need to be sent and received by the backend.

inline virtual bool NeedsExtraBatch() override

Returns

true Never

Returns
