I could finally install MARSSx86 and is working much better than I was
expecting (considering that I'm using Linux Mint 13 inside VirtualBox)!!!!
Now my problem is related to how convert the output to an energy XML
profile (used by McPAT). Then I received the followin errors:
1) "Traceback (most recent call last):
File "marss2mcpat.py", line 6, in <module>
path = os.path.dirname(sys.argv[0])
NameError : name 'os' is not defined"
*
Solution:* moved the subsequent imports to the beginning of the file,
before the "try/except" block.
------------------------------------------------------------------------
2) "Parsing YAML... Malformed YAML file? Lazy error checking says: mapping
values are not allowed in this context
in "../ptlsim.log", line 2, column 10
*Solution:* manually removing all the lines that are causing errors
(basically, the ones that doesn't have ":" and the comments done using
"//").
------------------------------------------------------------------------
3) "Traceback (most recent call last):
File "marss2mcpat.py", line 457, in <module>
statsDict = ReadFile(args.marss, args.cpu_mode)
File "marss2mcpat.py", lin 37, in ReadFile
if mode in segment['simulator']['tags']:
KeyError: 'simulator' "
*Solution:* looking for one.
Maybe some relevant additional information:
- the MARSSx86 code was grabbed from its GitHub, so it is the current
version;
- as XML file input, I've tried to use "Alpha21364.xml", "ARM_A9_2000.xml"
and "Xeon.xml". All those produced the same results.
Any ideas of what should I do?
Thanks in advance,
Cesar.
