Revision as of 15:26, 29 September 2008
This is a work in-progress. Everyone should feel free to extend this page with their experiences to help new users get started.
Contents
Input sets and Binaries
We can't provide the binaries or input files because of licensing restrictions, but It's not hard to build the binaries by yourself. In this short article, we will share our experiences about what we have done so far.
Build the cross-compiler for alpha machine
Download the crosstool-0.43.tar.gz from http://kegel.com/crosstool and modify these three lines in the demo-alpha.sh :
RESULT_TOP=where_you_want_to_put_the_compiler GCC_LANGUAGES="c,c++,fortran" eval `cat alpha.dat gcc-4.1.0-glibc-2.3.6.dat` sh all.sh --notest
Then follow the steps in the crosstool-howto page to build the cross compiler.
Build the SPEC2006 alpha binaries
Install the SPEC2006 from DVD and modify the CC, CXX, and FC in config/alpha.cfg.
For example: CC = /home/mjwu/crosstool/gcc-4.1.0-glibc-2.3.6/alpha/bin/alpha-gcc CXX = /home/mjwu/crosstool/gcc-4.1.0-glibc-2.3.6/alpha/bin/alpha-g++ FC = /home/mjwu/crosstool/gcc-4.1.0-glibc-2.3.6/alpha/bin/alpha-gfortran
Then follow the instructions in the ./Docs/install-guide-unix.html to build the binaries
For example: runspec --config=alpha.cfg --action=buld --tune=base bzip2
Expand M5 system call functions
Four extra system call functions are needed by SPEC2006. The functions can be modified in:
In m5-stable-mt/src/arch/alpha/linux/process.cc: /* 130 */ SyscallDesc("ftruncate", ftruncateFunc), /* 144 */ SyscallDesc("getrlimit", ignoreFunc), /* 341 */ SyscallDesc("mremap", mremapFunc<AlphaLinux>), /* 367 */ SyscallDesc("getcwd", getcwdFunc),
In m5-stable-mt/src/sim/syscall_emul.hh : ///Target getcwd() handler. SyscallReturn getcwdFunc(SyscallDesc *desc, int num, LiveProcess *p, ThreadContext *tc); //A simple implementation template <class OS> SyscallReturn mremapFunc(SyscallDesc *desc, int num, LiveProcess *p, ThreadContext *tc) { Addr start = tc->getSyscallArg(0); uint64_t length_old = tc->getSyscallArg(1); uint64_t length_new = tc->getSyscallArg(2); if ((start % TheISA::VMPageSize) != 0 || (length_new % TheISA::VMPageSize) != 0) { warn("mremap failing: arguments not page-aligned: " "start 0x%x length 0x%x", start, length_new); return -EINVAL; } if (start != 0) { warn("mremap: ignoring suggested map address 0x%x, using 0x%x", start, p->mmap_end); } // pick next address from our "mmap region" if(length_old < length_new){ warn("mremap size 0x%x %d -> %d",start,length_old,length_new); start = p->mmap_end; p->pTable->allocate(start, length_new-length_old); p->mmap_end += (length_new-length_old); start = tc->getSyscallArg(0); }else{ warn("mremap size 0x%x %d -> %d",start,length_old,length_new); } return start; }
In m5-stable-mt/src/sim/syscall_emul.cc: SyscallReturn getcwdFunc(SyscallDesc *desc, int num, LiveProcess *p, ThreadContext *tc) { char pathname[256]; int path_len = tc->getSyscallArg(1); getcwd(pathname,path_len); BufferArg path(tc->getSyscallArg(0), path_len); strncpy((char *)path.bufferPtr(), pathname, path_len); path.copyOut(tc->getMemPort()); return 0; }
Create the SPEC2006 processes for M5 SE mode
A good reference for the correct command line options can be found here: SPEC_CPU2006_Commands.
For your convenience, here is our benchmark python file for the M5 SE mode.

The SPEC2006 testing dataset results
We use the quard-core Xeon 2.5GHz with 16G memory machine. The operation system is 64bits CentOS 5.2. The timing results are from the simple cpu model and SPEC2006 testing data set.

Trouble shooting
You may encounter errors while executing the SPEC2006, and these two errors are common on 32-bits machine.
1. terminate called after throwing an instance of 'std::bad_alloc':
The M5 cannot allocate memory from you system. This happens a lot in the 32-bits machine, because only 3G memory can be used. To make life easier, you need a 64-bits machine.
2. bus error:
The same as above.
If you have any questions, please email to M5 Mailing-List or contact Meng-Ju Wu at mjwu@umd.edu.
