Changelog

0.2

  • Updated bsp_init to use the path relative to the host binary instead of current directory
  • Rewrote both Makefiles to be cleaner
  • Added bsp_raw_time, now implemented in assembly
  • Added some documentation
  • Rewrote all examples to use the message passing system instead of hardcoded addresses
  • Separated the epiphany library into multiple files
  • Added 'assembly' target in makefile to produce readable assembly
  • Added ebsp_ext_malloc for allocating external memory, using self-made allocation table system
  • Modified bspbench to use less iterations for higher h-values
  • Makefile now detects architecture and uses cross compiler if needed
  • Implemented BSP abort using an Epiphany instruction that halts all cores, and host code to handle this
  • Added example that will show usage of all primitives
  • Moved large BSP functions to external memory
  • Implemented BSP message passing from host to core and back
  • Makefile updated, library now optimized for size
  • Epiphany core data is no longer tightly packed for better speed and reduced code size
  • Implemented BSP Message passing
  • Host does no longer take part in synchronization
  • All cores now use the same space to store data payloads (mutexed)
  • All bsp_push_reg logic now happens on the epiphany side
  • Added benchmark comparing bsp_put to bsp_hpput
  • All shared structures now have maximal packing because the two compilers use non-compatible alignments
  • All cores now use the same memory for bsp_put data payload allowing a lot larger payloads
  • Moved bsp_var_list from on-core memory to external memory
  • Host no longer interferes with variable registrattion
  • Added bsp_get, bsp_hpget and bsp_put
  • Fixed timer to use real time instead of clockcycles
  • Added ebsp_message
  • External memory is now in one large block
  • Fixed hardcoded BSP addresses to no longer overlap
  • All BSP variables are stored in a struct
  • Host checks for MAX_N_REGISTER and outputs warning if reached.
  • Added memory inspector with ebsp_inspector_enable().
  • Added LU decomposition example
