Hi List,
Now I compiled MiBench as well as CPU 2000 (both have to be one
benchmark by one benchmark) for M5, using options simply "-static -o XXX
-lm" removing "-O3", and found the compiled binaries executing in M5
properly. Lucky me...
However, I also found those benchmarks running, especially CPU 2000 like
gzip, extremely slow for m5.debug. I truncated the input file for gzip
to only 34K but the simulation still takes forever...

The makefiles I used for MiBench and MediaBench are nothing special.
They should work just fine. As Max mentioned earlier, you just have to
make sure that you create statically linked binaries.
One thing I noticed is that you're using an older GCC (3.4.3). Did you
try GCC 4.3.2?

Hey Max,
As you said, I did put -static. However, I'm not sure whether "-im" is
appropriate in this scenario.
If anyone has successfully compiled MiBench or CPU 2000, could you share
your Makefile with me?
Thanks.

Hey,
1) Did you compile the benchmarks statically? Because if you want to run
them on M5 everything you run is the compiled binary. So dynamic libraries
cannot be load.
2) For SPEC CPU2000 the situation is indeed more complicated. I compiled
some benchmarks of SPEC CPU2006 and had to do the following things in the
config-file (make sure you pick a config-file with properties very similar
to your machine):
-Select the propper compiler:
CC = gcc
into
CC = /DIRECTORY OF
CROSSTOOL/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc
-Modify the compile-flags (add the "static" flag) in the "optimization"
section:
## Base is low opt
default=base=default=default:
COPTIMIZE = -O2 -static
CXXOPTIMIZE = -O2 -static
FOPTIMIZE = -O2 -static
However I recommend you to build SPEC CPU 2000 first for your native
machine. This could be already difficult. If it works, then try it for
ALPHA_SE
Greets,
Max

Hi all,
I want to cross-compile some benchmarks so that I can run them in M5. I'm
using a ALPHA_SE mode M5 on a x86_64 Ubuntu machine. Potentially I target to
use MiBench or SPEC CPU 2000. I downloaded the pre-compiled cross-compiler
for Alpha from m5sim.org.
1) For MiBench, it has a simple src code/data structure with a simple
Makefile. For example, qsort, I modifed the Makefile of it as follows:
-------------------------------------------------------------------------------------------------
FILE1 = qsort_small.c
FILE2 = qsort_large.c
all: qsort_small qsort_large
qsort_small: qsort_small.c Makefile
/export/research57/weixun/tools/M5/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc
-static qsort_small.c -O3 -o qsort_small -lm
qsort_large: qsort_large.c Makefile
/export/research57/weixun/tools/M5/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc
-static qsort_large.c -O3 -o qsort_large -lm
clean:
rm -rf qsort_small qsort_large output*
-------------------------------------------------------------------------------------------------
I used the option "-lm" since the original "-lc" lead to errors like
"undefined references to 'exp'". If "-L
/export/research57/weixun/tools/M5/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/lib"
is used, the error still remains.
The compilation is successful. However, if I run it using
configs/example/se.py, I got the errors:
-------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------
Other benchmarks in MiBench shows similar errors or just simplely hang on
"info: Increasing stack size by one page.".
I guess the compile options are not correct or the right library is not
linked. Please help...........................
2) For SPEC CPU 2000, it is more complicated. I copied the entire CD to a
local directory. The problem is I do not have the su privilege on the
machine I worked on. So the install.sh does not work correctly. Is there a
simpler way for cross-compile SPEC CPU 2000 benchmarks (or at least some of
them) for M5?
Thanks!!!
