Detailed Description

Derived application interface class which spawns simulation codes using system calls.

SysCallApplicInterface uses a SysCallAnalysisCode object for performing simulation invocations.

Member Function Documentation

void derived_synch

(

PRPQueue &

prp_queue

)

[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.

References ApplicationInterface::completionSet, and SysCallApplicInterface::derived_synch_kernel().

void derived_synch_nowait

(

PRPQueue &

prp_queue

)

[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.

References SysCallApplicInterface::derived_synch_kernel().

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.
