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

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!!!
