Dear GEMS User
I have tried to run SPLASH2 benchmarks
on GEMS1.4 and SIMICS 3,0 on DNUCA environment.
After initialization of RUBY, and “c” is executed.
However, when I run executable file of
benchmark on Serengeti console, “Possible Deadlock
detected” error occurred.
In mfacet.py file

1) Why deadlock does occur?
2) I think that
$GEMS/ruby/network/simple/Network_File/NetworkFileMaker doesn’t make following 3 lines.
So I copied that line from other
pre-existing network file. Is that right?
Is there another way to make network
file as I want?

ext_node:Directory:0 ~
ext_node:Collector:0 ~
Welcome any advice.
Thanks in advance.
