[gem5-users] cloud for gem5
Hi Ciro, do you know of a free cloud to use gem5, because I always took a lot of time to run the kernel armv8 on the fs.big.LITTLE mode. Thanks, com_. ___ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
[gem5-users] the instructions that are responsible for the number of access to the cache and energy consumption.
hi all, I need to do an analysis on the change of time of simulation of a parsec 3.0 application (ex: blackscholes) in gem5 ,armv8 big.LITTLE mode , and I do not know the statistics (the instructions of file stats.txt) which are responsbales on the change of execution time (for example the instructions that are responsible for the number of access to the cache, energy consumption ... etc) please if you have an idea help me. Thanks advance; com_. ___ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
