Re: [gem5-users] Is it possible to write the output file of an application into linux.img when full system gem5 runs the application.

It works now. The problem seems due to application execution problem. Thanks! Zhiguo From: GE ZHIGUO Sent: Tuesday, July 17, 2012 1:07 PM To: gem5 users mailing list Subject: RE: [gem5-users] Is it possible to write the output file of an application into linux.img when full system gem5 runs the

Re: [gem5-users] Simulating multiple machines in GEM5

You can simulate as many machines as you want, but you may or may not be able to hook them together like you want to. The barrier to simulating more than two machines on a standard network is that there is no Ethernet switch model, just a simple link. So you can hook two machines directly togethe

Re: [gem5-users] Simulating multiple machines in GEM5

Yes, it is possible see fs.py and included .py s. you should create 3 (or more) "system" and make them child of "root" when simulating one system, "root" has only one child. see m5out/config.ini. Best Seyed Hossein On Tue, Jul 17, 2012 at 9:41 AM, Anirudh Sivaraman wrote: > Hi > > I was wonder

[gem5-users] Simulating multiple machines in GEM5

Hi I was wondering if there was a facility to simulate 3 or more networked CPUs within one GEM5 process. I am looking for something like --dual, but which generalises to >=3 processor instances. Anirudh ___ gem5-users mailing list gem5-users@gem5.org ht

Re: [gem5-users] Is it possible to write the output file of an application into linux.img when full system gem5 runs the application.

Hi, Tony I followed the instructions in the webpage that you provided. Now, I can see the output file from the directory. However, when I tried to read the file (such as ls output_file), error was encountered: input/output error. Steps done: 1. Modify fsconfig.py #class CowIdeDis

Re: [gem5-users] Problem booting O3CPU on X86 FS

Hi Anderson Because of Alpha was the basis architecture for M5, I suppose it is also valid for any cpu architecture: (from FAQ at http://www.m5sim.org/Frequently_Asked_Questions#How_many_CPUs_can_M5_run.3F) How many CPUs can M5 run? - There is no inherent limit in M5 (other than simulation s

Re: [gem5-users] Gem5 running PARSEC setting help

You cannot see the output file when GEM5 using a extra file layer in which the output file will not be written to disk file. By running application in the linux on GEM5 directly instead of running script, You can specify the output file and use cat command to check the output. Regards, Zhiguo F

Re: [gem5-users] Gem5 running PARSEC setting help

Hi Hao, The thing is I don't even know whether my PARSEC actually runs or not. Is there any way to tell that? In my original question, I ran two traces blackscholes and dedup, there is no difference in stats.txt file, IPC for each core are exactly the same. Even remove PARSEC script file (.rcS fil

Re: [gem5-users] Gem5 running PARSEC setting help

Try removing the switchcpu command. Not sure whether it really works. If you do want to use simple CPU to fast forward to your program, I will suggest create a checkpoint and restore with O3 CPU. Bonzi On Mon, Jul 16, 2012 at 3:26 PM, Xi Chen wrote: > Hi all, > > I'm a little confused with th

Hi all, I'm a little confused with this problem now. I think the PARSEC script did not run supported by another evidence is that I tried to dump stats every n ticks by modifying .rcS file from: cd /parsec/install/bin /sbin/m5 switchcpu /sbin/m5 dumpstats /sbin/m5 resetstats ./blackscholes 16 /pars

Hi all, I have some setting problems with running PARSEC on Gem5. First I have download full system file for ALPHA Gem5 and got it run. Then I downloaded PARSEC image file from UT website and unzip it and put it under folder m5_system_2.0b3/disks/ . After that I modifed SysPaths.py and Benchmark

Re: [gem5-users] Problem booting O3CPU on X86 FS

The boot process works fine until 4 cpus (in my case O3CPU), in X86 and ALPHA. But when I used more than 4, the boot don't finish (in X86 and ALPHA). I used the last gem5-stable version, and the last gem5 avaliables. The last time that I tried to boot 8 03CPU, the boot took 15 hours to boot only

Hi Xi, The clock will indeed be printed as a period (and with the unit being Ticks). You can set a period as low as 1 tick if you want, so with the default resolution that would correspond to 1THz(!) Andreas From: gem5-users-boun...@gem5.org [mailto:gem5-users-boun...@gem5.org] On Behalf Of X
