Thomas Preud'homme 3341546c75 commtech: calc lib take 1 argument on command line 2009-07-01 02:36:11 +02:00
Thomas Preud'homme 7a1610961c commtech: BUGFIX unwanted optimization 
Replace prod += 42 by prod += fourty_two where fourty_two is a volatile
variable to avoid replacement of the loop into a prod += 42 * nb_loop

Thomas Preud'homme 243d8810f1 commtech: avoid a double free corruption 
Remove srand and rand function call as they generates double free
corruption (???)

Thomas Preud'homme e04818645a commtech: Add a new calculation method 
This calculation performs only a loop and avoid cache pollution
 2009-06-30 22:37:55 +02:00
Thomas Preud'homme c98db4b4ba commtech: do_calc() return a void ** 
This respect what we claim to send to the send() function and allow to
reduce the FAKE_NURSERY_START. Thus we are sure gcc won't optimize the
second part of the if in include/jikes_barrier_comm.h

Thomas Preud'homme 7bfc46db78 commtech: Delete pages free 
Pages cannots be freed as fast as they are allocated, so this whole
mecanism can only delay the kernel panic. It's wiser to exit badly if
too much memory is consumed

  init_library once and init_thread_comm by each thread
* cont is now directly accessed by main
* list of struct communication_assoc -> array of struct thread_comm
* struct communication_channel -> struct comm_channel

  stored
 2009-06-16 13:22:08 +02:00
Thomas Preud'homme 09bff9869e communication technique benchs: We send addresses

Thomas Preud'homme 02db9b77f6 Bug in communication techniques bench 
* prod_idx and cons_idx aren't declared volatile so compiler could
  sur-optimize access to these variable and lead to a deadlock
 2009-06-12 00:39:25 +02:00
Thomas Preud'homme 471fdef61e Bug in communication techniques bench 
* producers can finish before consumer and thus free the thread-local
  storage they have which could lead to sigsegv from consumer
