The SimFlex project is pleased to announce that Flexus 2.1.1 has been
released and is available on the SimFlex web page.
http://www.ece.cmu.edu/~simflex
This release fixes a bug, introduced in 2.1.0, that causes out-of-order
simulations to deadlock. The bug is triggered if a load instruction in a
branch delay slot is annulled and then reinstated. Anyone using .OoO
Flexus targets should upgrade immediately. There are no other changes in
this release.
We have also posted an updated Getting Started Guide with several minor
corrections.
Please report any difficulties with the new release to the mailing list.
Here are the notes from the version history:
Flexus 2.1.1 7/6/2006
Release Manager: Tom Wenisch
- Fix deadlock in OoO core when an anulled load is reinstated

Hi,
I followed the new Getting Started Guide through the timing experiments
with the sampled simulation using the DSMFlex.OoO simulator and
everything worked fine. Now, I'd like to try the same thing with the
CMPFlex.OoO simulator instead, and I was wondering what changes I'd have
to make.
I tried running:
./create-initial-flexpoint TraceCMPFlex
./create-flexpoints TraceCMPFlex
./run-timing-jobs 0 26 -ma -cfg OoO CMPFlex.OoO
but that gives the following errors:
16 <uFetchImpl.cpp:123> {0}- Loading state: flex_state_in/sys-L1i for
ufetch order L1i cache
17 <uFetchImpl.cpp:167> {0}- Expected '<' when loading checkpoint
18 <uFetchImpl.cpp:132> {0}- Error loading checkpoint state from file:
flex_state_in/sys-L1i. Make sure your checkpoints match your current
cache configuration.
19 <uFetchImpl.cpp:133> (<undefined>[<undefined>]) {0}- Assertion
failed: ((!(false))) : <undefined>
Do you have any suggestions as to what I need to change?
Thanks,
Jason
