Daffie Module Wrapper(Makefile Example) AuditoryNerveIFR: AuditoryNerveIFR.o ${OBJ} ${MODLIB} ${RES} $(LD) $(LDFLAGS) -g AuditoryNerveIFR.o ${OBJ} ${RES} ${LIBS} -o $@ AuditoryNerveIFR.o: efievent.h efieventdef.h module.c $(CC) -c $(CFLAGS) -DMODULE=AuditoryNerveIFR -DNIN=1 -DNOUT=1 module.c -o $@ BM_Gamma_Tone: BM_Gamma_Tone.o ${OBJ} ${MODLIB} ${RES} $(LD) $(LDFLAGS) -g BM_Gamma_Tone.o ${OBJ} ${RES} ${LIBS} -o $@ BM_Gamma_Tone.o: efievent.h efieventdef.h module.c $(CC) -c $(CFLAGS) -DMODULE=BM_Gamma_Tone -DNIN=1 -DNOUT=1 module.c -o $@ InnerHaircell: InnerHaircell.o ${OBJ} ${MODLIB} ${RES} $(LD) $(LDFLAGS) -g InnerHaircell.o ${OBJ} ${RES} ${LIBS} -o $@ InnerHaircell.o: efievent.h efieventdef.h module.c $(CC) -c $(CFLAGS) -DMODULE=InnerHaircell -DNIN=1 -DNOUT=1 module.c -o $@ Scientific Computing and Visualization

  8. Earlab Upper Layer Protocol • Configuration • Static (meta) data • Number and types of inputs, outputs, etc. • Runtime • Input/output sizes and wiring • EFI function calls • Load, Start, ReadParameters, Advance, Stop, Unload • Data • Status • Control • Probes, etc Scientific Computing and Visualization

  9. Services • Job initiation • Resource and status monitoring • Logging (remote console) • Control • File sharing • Data monitoring (probes) Scientific Computing and Visualization

  10. Earlab Experiment Earlab Module 1 Control . . . Earlab Module 2 File Server event server Monitor Console Earlab Module n Probe Logger Scientific Computing and Visualization

  11. Agent/Client Initiation Daemon (agentd) • Run on each host that is willing to run modules or host an experiment (i.e. run an event sever) • Given list (directory) of modules • Provides remote logging capabilities • stdio is encapsulated into DAFFIE events • Hooks for authentication and authorization (access controls) • Deals with OS specifics of process creation • Control, logging and agent execution may all be in separate DAFFIE worlds Scientific Computing and Visualization

  12. Earlab Architecture Meta World Earlab Master agentd agentd module module module module Host 2 Host 1 Experiment 2 Experiment 1 Experiment n Scientific Computing and Visualization

  13. Issues/future work • Exception catching and handling • File sharing • Authentication and authorization • Data transport • Streaming • Tunnels • Distributed control • EFI V3 (Spike data) • GUI (?) • Configuration layout • Probes • Remote and Display Wall graphics • 3D • Direct X/OpenGL • Better hosting (eventd) • DNS aware Scientific Computing and Visualization
