v1.6.0

Release version 1.6.0

2019.09.06

New Feature

• SPiDER now supports Apollo optimizations
  • Apollo can be skipped with SKIP_APOLLO in CMakeLists.txt

Changes

• Papify feedback now stops analyzing data depending on the number of actors being executed

Bug fix

• Fixed bug where papify feedback analysis got stuck (only GRT is enabled)

v1.5.0

Release version 1.5.0

2019.08.28

New Feature

• PAPIFY now has different modes:
  • papify=dump: dump PAPIFY info into csv files;
  • papify=feedback: PAPIFY (timing) feedback is retrieved by GRT and timings are updated;
  • papify=both: both modes active at the same time;
• SPiDER now includes information about energy consumed by an actor executed on a specific PE;
• SPiDER now includes information about energy consumption models associated to actors executed on PEs;
• PAPIFY in SPiDER with feedback mode active:
  • energy feedback is also supported. Energy consumption models based on PAPIFY events are considered when updating the energy consumption;
  • energy consumption of one actor being executed on a specific PE type is updated if possible;

v1.4.0

Release version 1.4.0

2019.05.21

Bug fix

v1.3.0

Release version 1.3.0

2019.05.15

New Feature

• Complete Refacto of PThread Platform: all communications are now passively blocking, threads will not take 100% CPU for synchronization.
• SRDAG output shows persistent delay inormation
• Static graphs are now only scheduled on first iteration.
• Adding new greedy scheduler to scheduler list
• Adding new SR-DAG less Intermediate Representation (sr-dag remains the main IR for now however)
• Proper handling of SIGINT signal on Linux platforms.
• Adding proper Logging systems inside Spider for outputing messages.
• Adding spiderException method for throwing specific exception with printf like messages.

Changes

• Enhance Special Actor Memory allocation allowing reduced footprint.
• Move some platform specific types (unsigned long, long, char, etc.) to standard types.
• Changed parameters implementation, reducing number of expression evaluation and making more explicit dependencies between parameters.
• Changed communication system. Communications are now based on an asynchronuous notification system.
• Optimized communications with less synchronisation required.
• Refactored all Rational class to more modern C++.
• Improved performance of BRV computation when using LCM.
• Improved performance of expression evaluation.
• Refactored Scheduler with less code duplication, using more POO.
• Memory allocation is now non page aligned by default (this reduce drastically the memory need of SPIDER)
• Changing Schedule structure.
• Overall clean up of the code base with clang tidy rules.
• Overall clean up of exception messages inside entire code base.
• Overall clean up of dead code and code smells.
• Update travis file: now testing cross compilation

Bug fix

• Fix Graph transformation for actors with repetition is equal to 0.
• Fix Floor and Ceil Expression Resolution.
• Use float for Expression Resolution as Preesm does.
• Fix display of reserved memory usage.
• Avoid reallocation of already allocated fifo in memory allocation.
• Fix double allocation of lrt[0] and lrtCom_[0] in platform pthread.
• Fix memory allocation problem on 64bits systems.
• Fix SRLinker problems when an input interface needs a sink vertex.
• Fix memory allocation and free when size is 0 and pointer is null, respectively.
