Hi,
I need help with running Parsec (preconfigured files) with ruby.
however, everything works fine when I run in FS mode with for example:
build/ALPHA/gem5.opt configs/example/fs.py --script=parsecScript.rcS
--kernel=vmlinux_2.6.27-gcc_4.3.4 --num-cpus=4
also the following configuration works perfectly fine:
build/ALPHA/gem5.opt configs/example/ruby_fs.py --topology=Mesh
--script=parsecScript.rcS --kernel=vmlinux_2.6.27-gcc_4.3.4 --num-dirs=2
--ruby
but as soon as I add the --num-cpus option with 2 or more cpus the
execution gets stuck. This means that it boots till the line*io
scheduler cfq registered (default)* and then it hangs there for ~24
hours until I aborted.
The usual execution with one CPU and ruby takes usually less than 30min.
A Internet search for this line brought up several threads where Linux
users have problems with peripherals during boot which might be due to
kernel issues. !? :-(
solutions were:
1. Add kernel parameter "pci=noacpi" and/or disable ACPI in BIOS
2. Add kernel paremeter "noapic" and/or disable IOAPIC in BIOS
so I'm wondering...is this even possible in gem5? I'd guess no.
Could anyone pls help me with that!? I see several people executing
paersec with more than 4 cpus with no issues...what am I doing wrong?
cheers and thanks in advance,
Kris
Ps: my script:
#!/bin/sh
# File to run the blackscholes benchmark
cd /parsec/install/bin
/sbin/m5 dumpresetstats
./blackscholes 4 /parsec/install/inputs/blackscholes/in_4.txt
/parsec/install/inputs/blackscholes/prices.txt
echo "START"
cat /parsec/install/inputs/blackscholes/prices.txt
echo "Done :D"
/sbin/m5 exit
and the command line output:
