Re: [gem5-users] Gem5 and McPAT error

[Weizheng Xu]

Dear all, I simulated the gem5 with full system mode and the command is "sudo build/ALPHA/gem5.opt configs/example/fs.py --script=./configs/boot/canneal_8c_simsmall.rcS --cpu-type=detailed --num-cpu=8  --caches --l2cache --num-l2caches=2 --l1d_size=32kB --l1i_size=32kB --l2_size=8MB --l1d_assoc=4 --l1i_assoc=4 --l2_assoc=16 --cacheline_size=64 --mem-type=NVMainMemory --nvmain-config=../nvmain/Config/RRAM_ISSCC_2012_4GB.config -F 5000000000 -I 2000000000” and get the stats.txt like below.  Then I use "python GEM5ToMcPAT.py stats.txt config.json template-x.xml” to transfer the output files of gem5 to the available input of McPAT, named as mcat-out.xml (the input of McPAT) here.  But there have some warning here like this"Reading GEM5 stats from: stats.txt Warning (stats): system.iocache.tags.avg_refs is nan. Setting it to 0 Warning (stats): system.iocache.avg_blocked_cycles::no_mshrs is nan. Setting it to 0 Warning (stats): system.iocache.avg_blocked_cycles::no_targets is nan. Setting it to 0 Warning (stats): system.cpu0.kern.mode_switch_good::user is nan. Setting it to 0 Warning (stats): system.cpu0.kern.mode_switch_good::idle is nan.

Setting it to 0 Warning (stats): system.l2.avg_blocked_cycles::no_targets is nan. Setting it to 0 …... I don’t know how to solve this warning and guess this is not the problem here which lead to the error below. So I ignore them. Then I use"./mcpat -infile mcpat-out.xml “ to run the McPAT, and can not get the output of McPAT. The error also shown as "McPAT (version 0.8 of Aug, 2010) is computing the target processor...   some value(s) of number_of_cores/number_of_L2s/number_of_L3s/number_of_NoCs is/are not correct!” Ps: I use the ubuntu14.04 LTS system and the McPAT in gem5/ext/mcpat file All helps appreciate! The output file of gem5 is too big to put here. You can get it with this link https://drive.google.com/drive/folders/13yTj7gVtvi-mUjFUB16jgg2sAqmwSe3-?usp=sharing. The template is used for transfer and the result of transferred(input of McPAT tools) are listed here.  Sorry to bother you guys.

The best way is to create your own parser.  Share the output file in order to check what it is wrong.

But I still have the same problem here. I have check the repository of the person who help me before https://github.com/H2020-COSSIM/cMcPAT, but I did not find the template in his files. I am not sure how can I change the template because when I change the value of number of cores and others, they have the same problem.  Any help appreciate.

It would be better if you used that one. Now concerning your issues. You need to make sure that the system that you are trying to simulate in gem5 matches with the template that you are trying to use in McPAT. It is assumed that you need to make changes in the template xml file to match it with the gem5 system. Check the proper instructions on how to do that. You can also check the modified McPAT and conversion scripts in my repository here: https://github.com/H2020-COSSIM/cMcPAT Best regards, Andreas On Mon, Sep 24, 2018 at 11:10 PM Weizheng Xu <weizhengxu2...@u.northwestern.edu> wrote: Dear all, I use gem5 get the full system simulation results and want to use McPAT to get the power model.  I use the Gem5ToMcpat.py and template_xeon.xml  gotten from website to translate the stats.txt to the output.xml, which can be read as input by McPAT. But when I use this output.xml as a input for McPAT  (I use command ./mcpat -infile /home//Desktop/test/gem5/ext/mcpat/out.xml in the terminal to run the McPAT), I got the error shown as following: "McPAT (version 0.8 of Aug, 2010) is computing the target processor... some value(s) of number_of_cores/number_of_L2s/number_of_L3s/number_of_NoCs is/are not correct!” I tried to change these values in the template_xeon.xml but still failed with this problem. I really don’t know how to solve this problem. PS: I use ubuntu16.04 LTS and gem5. I use the McPAT provided in the gem5/ext file and with version of 0.8 Any help appreciated, thanks Weizheng _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
