[Gems-users] Running GEMS on Linux/SPARC target

[Shougata Ghosh <shougata@xxxxxxxxxxxxx>]

Hi
Are there any issues with running GEMS with a Linux/Sparc target 
machine? I am simulating a 16-processor sparc machine in simics (using 
their bagle script) and was trying to run the transactional 
microbenchmark (tm-dequeue) that comes with GEMS. I loaded ruby module 
but not opal since I'm only concerned with the memory access patterns. I 
used the "MESI_SMP_LogTM_directory" cache protocol. I am giving a 
screenshot of the error I got:
simics> run-command-file file = setup_ruby.sh
Turning D-STC off and flushing old data

The first signs of problems is ofcourse cpu17. No idea where that came 
from with 16 processors! Before I investigate the problem any further, I 
wanted to figure out if there are any known issues with running 
transactional benchmarks using magic instructions with Linux/Sparc 
setup. I know it has been made to work with Solaris/Sparc setup. Does it 
not run on Linux/Sparc machines? Has anyone tried using magic 
instructions with Linux/Sparc setup? Any feedback will be really useful.
Thanks
