Hi,
I'm trying to execute splash2 benchmark with m5 2.0 beta 5. The host
system
is GNU/Linux i686, and I built m5 for alpha isa. I built full system
because
it seems this is robust as well as easy to build according to the
document.
I got pre-compiled cross-compiler from m5 website:
http://www.m5sim.org/dist/current/alpha_crosstool.tar.bz2
As a warning this compilers apparently doesn't support NPTL and uses
LinuxThreads instead.
By using this, I could build most programs in splash2 benchmark
suite. (I
referred to http://www.capsl.udel.edu/splash/Download.html )
We have a precompiled set of SPLASH benchmarks on the d/l page. The
easiest thing is probably to use them unless you would like the kernel
overheads to be added in.
I think two important steps still left:
1. inject splash2 binaries into disk image
2. execute benchmark driver.
It seems m5 comes with scripts for splash2 in that there are run.py
and
cluster.py in the configs/splash2/ directory. When I executed
run.py, I got
an error.

The splash2 scripts only work with syscall emulation (SE) mode.
I don't think there is any typo. /dist/splash2/codes exists. Also, I
could
run fs.py script by using the following command. I think it means
that m5 is
correctly built and directory structure is not incorrect.
$ ./build/ALPHA_FS/m5.debug configs/example/fs.py
--script=./configs/boot/hello.rcS --timing
As a beginner, it's not easy to find out how to solve this problem.
I wish
some gurus help me for this matter.
Another question is how to inject splash2 binaries into disk images.
Since I
didn't want to build Linux kernel from scratch, I downloaded disk
image from
m5 website, http://www.m5sim.org/dist/current/m5_system_2.0b3.tar.bz2
The FAQ on the webpage describes how to do this. However, I'm not sure
that the precompiled binaries on the webpage will actually work in
full-system mode since they use the PARAMACS threading library and not
pthreads.
