Thomas Preud'homme d8c16a4aa3 Merge branch 'bqv2_buf_end' 2012-07-07 23:14:15 +02:00
Thomas Preud'homme 4914b0dcdd Add CSQ (2/1) and CSQ (2/32), Del CSQ (2/2) 2012-03-27 00:31:16 +02:00
Thomas Preud'homme a80decaef4 [commtech] Provide 64 cache lines version of algos 
* Provide for BatchQueue, CSQ, FastForward, MCRingBuffer and GOMP stream
  a version using 64 cache lines in total for all buffers.
* Rename common version from _common_comm.h to _common.h to avoid
  considering them as communication technique on their own
 2012-03-26 16:44:30 +02:00
Thomas Preud'homme 5840b57937 [commtech] Provide more CSQ configs 
* Rename CSQ configs to csq_<nbr_buffers>_<size_buffer>_comm.h
* Add several configs
* Default config is csq_comm.h

Thomas Preud'homme f9aa3b227a CSQ's article suggest SUB_SLOTS should be 64. 2012-03-19 20:40:13 +01:00
Thomas Preud'homme 7c4a484989 [commtech] Simplify if's in send() 
Test sender_ptr against the end of the current buffer via
channel->sender_ptr_end

Thomas Preud'homme a20c9a8a21 [commtech] BatchQueue v2 
Uses 2 mapping to the same structure to avoid prefetching of the
producer semi-buffer by the consumer. The idea is to access everything
through mapping 1 except semi-buffer 2 which is accessed through mapping
2.

Thomas Preud'homme c6786815cd Add native algo from OpenMP stream extension 
Add native algorithm from OpenMP stream extension. This require adding
one function in commtech.h: end_producer(). This function does nothing
for all communication algorithm but gomp_stream (the algorithm added by
this commit).

Thomas Preud'homme 756a701466 [commtech] Refactor to chain more than 2 nodes 
* Refactor the source to be able to chain more than 2 nodes together
* Compile all binaries by default (binList must be set manually in
  lancement.sh to run only a subset of the binaries

Thomas Preud'homme 5d71bc53f1 [commtech] Varying size of buffer for BatchQueue 
Create several variation of BatchQueue, each with a different buffer
size: batch_queue_1024, batch_queue_512, ..., batch_queue_2.

Thomas Preud'homme 023552a4de [commtech] Prevent prefetch in batch queue 
Prevent prefetch of state variable in BatchQueue by adding padding
between the buffers and state variable.

Thomas Preud'homme 22c97ab418 [commtech] Make BUF_SIZE definition be per tech 
Don't define BUF_SIZE globally anymore, but per communication technique

Thomas Preud'homme 7c515200e7 [commtech] Remove asm_cache from the comm techs 2011-03-02 13:19:22 +01:00
Thomas Preud'homme 90b7a8007b [commtech] Rename c_cache to batch_queue 2011-03-02 13:19:22 +01:00
Thomas Preud'homme aef40ff651 [commtech] Fix cache line size 
Cache line size in current processors (at least the one used for tests:
cerclon) is 64 bytes, not 128. Thus modifying the declaration in
commtech.h
 2011-01-25 17:25:38 +01:00
Thomas Preud'homme 975411a824 Split CSQ in 2 communication techniques. 
* Divide CSQ in 2 communication techniques: one with 2 slots (as in
  BatchQueue aka c_cache) and one with 64 slots (as in the article)
* Rename fake communication technique in none communication technique
  and disable any activity (send no longer does anything)

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
