Member Function Documentation

void derived_synch

(

PRPList &

prp_list

)

[inline, virtual]

Check for completion of active asynch jobs (tracked with sysCallSet). Wait for at least one completion and complete all jobs that have returned. This satisifies a "fairness" principle, in the sense that a completed job will _always_ be processed (whereas accepting only a single completion could always accept the same completion - the case of very inexpensive fn. evals. - and starve some servers).

Reimplemented from ApplicationInterface.

void derived_synch_nowait

(

PRPList &

prp_list

)

[inline, virtual]

Check for completion of active asynch jobs (tracked with sysCallSet). Make one pass through sysCallSet & complete all jobs that have returned.

Reimplemented from ApplicationInterface.

int derived_synchronous_local_analysis

(

const int &

analysis_id

)

[inline, virtual]

This code provides the derived function used by ApplicationInterface::serve_analyses_synch().

Reimplemented from ApplicationInterface.
