  1. MIMA prototype design Proposal for a design implementing the three major FASE execution modes Luigi Paioro – ON 9.2 Face to face meeting, Milan, Jul 16th-17th 2009

  2. The System Layers Consumer Client API Middleware API Service Provider Luigi Paioro – ON 9.2 Face to face meeting, Milan, Jul 16th-17th 2009

  3. The Execution Modes [1] • Inline mode: everything lives within the application process Components Wrapper Package Manager Direct Implementation Luigi Paioro – ON 9.2 Face to face meeting, Milan, Jul 16th-17th 2009

  4. The Execution Modes [2] • Distributed mode: component and applications are different processes (maybe on different hosts) Package Manager Proxy Component Proxy SAMP Hub + Discovery System + Activation System + DVM = Package Manager Server IPC Components Container Luigi Paioro – ON 9.2 Face to face meeting, Milan, Jul 16th-17th 2009

  5. The Execution Modes [3] • Host execution mode: tasks are called as stand-alone programs running on the normal host shell “main” Container Shell execv + stdio/stderr Serialized PSet Luigi Paioro – ON 9.2 Face to face meeting, Milan, Jul 16th-17th 2009

  6. The Component Interfaces

  7. The System Interfaces

  8. Demo • Python container • Managed sub-process case • Direct invoke • In-line, distributed, host • Indirect invoke • In-line, distributed, host • Asynchronous invoke • In-line, distributed, “host” • Asynchronous invoke with handler • In-line, distributed • Logger interface used Luigi Paioro – ON 9.2 Face to face meeting, Milan, Jul 16th-17th 2009
