[m5-users] PARSEC 2.1 with m5 - segfault!
Hi, I'm a newbie to m5 and trying to run PARSEC 2.1on m5 under alpha in full system mode. First, I would like to thank people in UT Austin for publishing a tech report on this, it was very helpful. Now coming to the issue, even though I was able to boot the kernel in m5, when I try to run the any application in parsec suite, the app segfaults. Here are some more details: # ./build/ALPHA_FS/m5.opt ./configs/example/fs.py -n 1 --detailed --caches --l2cache and once the kernel boots, I do (as was mentioned in the tech report): /parsec/install/bin/blackscholes 64 /parsec/install/inputs/blackscholes/in_64K.txt /parsec/install/inputs/blackscholes/prices.txt This segfaults. The stack trace after crash looks like this: #0 0x000120016d8c in __libc_message () #1 0x00012001714c in __libc_fatal () #2 0x00012000c9cc in __libc_start_main () #3 0x00012218 in _start () This happens with all other applications in parsec suite. However, a simple hello world program does run correctly. My guess is there are some library incompatibilities which causes this crash. I used the kernel available in the m5 website ( http://www.m5sim.org/wiki/index.php/Download) under the Full System files section. I used the disk image from the UT Austin website ( http://www.cs.utexas.edu/~parsec_m5/linux-parsec-2-1-m5-with-test-inputs.img.bz2http://www.cs.utexas.edu/%7Eparsec_m5/linux-parsec-2-1-m5-with-test-inputs.img.bz2) for the parsec suite. So how do I go about fixing this and make PARSEC 2.1 work correctly with m5? -- Regards, Bhushan ___ m5-users mailing list m5-users@m5sim.org http://m5sim.org/cgi-bin/mailman/listinfo/m5-users
Re: [m5-users] PARSEC 2.1 with m5 - segfault!
Ah! The problem was, I was using the kernel from the m5 website instead of using the kernel packaged along with the tech report. That was the reason of the crash. Using the correct kernel did the trick. Thanks! On Wed, Mar 24, 2010 at 5:10 PM, ef snorla...@gmail.com wrote: What disk image are you using as well? You need to make sure the libraries in the disk image you are running are compatible with the benchmarks libc (your compiler) as well. As libc is not entirely statically link.

Re: [m5-users] PARSEC 2.1 with m5 - segfault!
Excellent, I'm glad that worked. Also keep in mind that your crosscompiler might need to be updated to reflect which version of the kernel you are using. More information on crosscompilation is in the tech report. Good luck, Joel On Wed, Mar 24, 2010 at 6:04 PM, Bhushan mo...@cs.virginia.edu wrote: Ah!
