Re: Is anyone know the present status of CBP-2 competition?

2006-10-23T16:07:10Z

Hi.
Your submission has been received. The program committee is currently
evaluating all submissions.

Is anyone know the present status of CBP-2 competition?

2006-10-23T06:38:31Z

Dear cbp2 group members:
We submitted files to the Realistic Track of CBP-2, but have not
received any response from the committee. Is the situation the same as
the other submissions'? We appreciate it if someone lets us know
information of how the CBP-2 is now going on.
Regards,
Koki Abe, Ph.D.

Update to the infrastructure

2006-09-14T18:05:51Z

Hi, folks.
I have made a minor update to the infrastructure. Some of you have
noticed extraneous traces that occur right before a context switch.
These traces are aparrently the result of my trace-gathering software
misinterpreting an exception as a normal branch. I have corrected the
traces so that these extraneous traces are no longer present. The

Hi, Ying.
The "4" is left over from an earlier version. It should read "8".
This causes no problem.

A question about the trace reading

2006-09-11T18:22:50Z

Hi, all,
In the souce "trace.cc" of cbp2 infrastructure, constant ASSOC is
defined as 8 at line 169. But from line 262, according to the comment
part, it was considered as 4, if I understand correctly. Part of the
codes are shown below.
// the byte is a correct prediction if it is less than 8;
// otherwise it is the first byte (a code) in a 9-byte trace

Hans,
You are right that the instruction at 0x8048c1f is not a branch; it is
the second byte in a register-register mov instruction. I have looked
through crafty at a lot of the transitions from 0x8xxxxxx to 0xcyyyyyyy
and they all have one thing in common: the 0x8xxxxxx instruction is an
instruction that refers to memory (either by branching or loading

weird sequences in trace files

2006-09-04T15:21:48Z

Hi all,
I have come across some weird sequences in the trace files that trigger
my attention (because they ruin my branch prediction scheme :-). These
sequences contain instructions that occur immediately before a context
switch (assuming that addresses 0xcyyyyyyy belong to the OS).
E.g., in crafty, you can find this sequence:

Hi, Gabe here...
I just wanted to chyme in with my two cents. First, it is true that
none of the finalists used the data values, and I recall Jared and
Chris saying that only a single non-finalist entry actually used the
values.
Independent on whether or not values are useful, how they might be
used, etc... from the perspective of running the contest, it is my

Re: reduced info from cbp-1

Hans,
The branch target is provided as the third argument to the 'update'
method in the 'branch_predictor' class, so your predictor will have
access to this value when it is updated.
It's not clear that comparing this year's entries the the previous
finalists would be valuable since the hardware budgets are different.

Hi Daniel,
I agree that access to all data values is not everybody's concern and
would leave you with a great deal of implementation work. But then, why
not use the same framework as in the previous contest?
Personally I would like to have access to the branch target. Can you
provide this? I believe it is useful to many people. Hongliang also

Hi, Yanos.
It might be possible to convince me that more information is a good
idea, but at this point I'm unable to devote the time and resources to
a change of this magnitude in the infrastructure.
However, let me be so bold as to disagree with you with respect to the
limits part of the contest. I think it will be an important
