Hi,
I have some questions about m5 v2.0b1.
1) For SE mode, is there a PARMACS m5-specific implementation I could
use in order to write multithreaded (shared memory) programs? I know I
can use pthreads in FS mode instead, but I would like to exploit the
SMT feature which is currently available only in SE.
In case that I can use the PARMACS model to write multithreaded apps, is
there a way then to map specific threads onto specific logical
processors (e.g. in a system with CMPs of SMTs, etc.)?
2) How can I learn about all the available statistics that are
correlated with a specific component (e.g. caches or branch predictors)?
How can I get them printed? Are they printed on m5stats file by default,
or should I add some extra lines on the simulation script?
3) Which is the proposed way to get accurate measurements and statistics
for the execution of a specific app in FS mode (i.e., excluding all
statistics regarding the boot process and so on)? Should I add on my
.rcS file the "m5 dumpstats" command before and after the execution of
the application, and then get a diff?
4) How can I start m5 with a checkpoint obtained from a previous
execution? I am not sure I have read something about on the wiki pages...
Thanks in advance,
Nick.
