Hi,
I once ran into the same problem. It is caused somewhere in the splash code,
where arrays are aligned to memory page boundary. I didn't solve the problem at
that time. I tried 8kB and 16 kB pages and neither worked. But if you remove
that piece of alignment code, it should run through.
Please post your solution if you are able to figure that out without removing
that code.

I'm trying to run SPLASH2 benchmarks in 4 detailed CPU cores M5_1.1.
I have little time, so I also try FS_mode.
I don't have alpha machine.
So, I tried to compile SPLASH2 benchmarks using cross-compiler.
I can compile hello warld program and can run this program correctly in
FS_mode.
But I try to run my compiled SPLASH2 benchmarks , get following error messege.

Though I look for a way to compile it, owing to lack of information ,I don't
know what to use PARMACS MACRO and option.
Could you tell me how to compile SPLASH2 benchmarks ?
Best regards,
this is my makefile----------------------------
TARGET = FFT
OBJS = fft.o
CFLAGS = -O2 -w
LDFLAGS = -lm -lpthread
MACROS = /home/fukumoto/splash/parmacs.upc.3/pthreads/c.m4.pthreads
x = *
$(TARGET): $(OBJS)
alpha-linux-gcc $(OBJS) $(CFLAGS) -o $(TARGET) $(LDFLAGS)
.SUFFIXES:
.SUFFIXES: .o .c .C .h .H
.H.h:
m4 ${MACROS} $*.H > $*.h
.C.c:
m4 $(MACROS) $*.C > $*.c
.c.o:
alpha-linux-gcc -c $(CFLAGS) $*.c
.C.o:
m4 $(MACROS) $*.C > $*.c
alpha-linux-gcc -c $(CFLAGS) $*.c
my environment----------------------------
OS :CentOS 4.2
ISA :x86_64
