Hi Lois,

  The ones that are tested and were used in our MICRO '07 paper is "MultiBitSel_N1_N2_N3_{Regular,Parallel}" for bit-select, and "H3_N1_N2_{Regular,Parallel}" for H3. N1 is size of the signature in bits, N2 is number of hash functions to use (>=1), and N3 is how many bits to skip before using bit-select (>=0).  See gen-scripts/config.py for examples, and the appropriate C/h files in ruby/system for implementation details.

My problem was in the script workloads.py, that it changed my configuration.

But I still have problems.
in the READ_WRITE_FILTER , What are the possible values?

Perfect_,LSB_Counting,NonCounting....???

Thanks
Lois

 Did you recompile?  rubyconfig.defaults are compile-time values.  You
can also change any value at runtime by doing ruby0.set_param

 Hi,

I'm starting with GEMS, and I'm trying  to modify the signatures in logTM.
The file rubyconfig.defaults is:

PERFECT_FILTER: true                // If true, use perfect physical
read/write filters
READ_WRITE_FILTER: Perfect_
PERFECT_VIRTUAL_FILTER: true        // If true, use perfect virtual
read/write filters
VIRTUAL_READ_WRITE_FILTER: Perfect_
PERFECT_SUMMARY_FILTER: true        // If true, use perfect summary
read/write filters
SUMMARY_READ_WRITE_FILTER: Perfect_

and I changed it for :


PERFECT_FILTER: false
PERFECT_VIRTUAL_FILTER: false
READ_WRITE_FILTER: LSB_Counting_
VIRTUAL_READ_WRITE_FILTER: LSB_Counting_
PERFECT_SUMMARY_FILTER: false
SUMMARY_READ_WRITE_FILTER: LSB_Counting_



But when I launch the deque microbenchmark I obtain  this out:


. . . .
XACT_MEMORY: true
XACT_ENABLE_TOURMALINE: false
XACT_NUM_CURRENT: 0
XACT_LAST_UPDATE: 0
XACT_ISOLATION_CHECK: true
PERFECT_FILTER: true
READ_WRITE_FILTER: Perfect_
PERFECT_VIRTUAL_FILTER: true
VIRTUAL_READ_WRITE_FILTER: Perfect_
PERFECT_SUMMARY_FILTER: true
SUMMARY_READ_WRITE_FILTER: Perfect_
XACT_EAGER_CD: true
XACT_LAZY_VM: false
.
.
.
.


... the simulation ignores my rubyconfig.defaults

In what I'm wrong?

Thanks in advance
Lois
