Hi all, I am a beginner with Gem5. I need to run PARSEC benchmarks on ALPHA. I followed instructions from the document provided by UT Austin.
In order to follow the document completely, I'm using an older version of Gem5 (http://repo.gem5.org/gem5/archive/549b72de8f72.tar.bz2) which supported --detailed flags. To build the older version, I am using gcc 4.5.3, python 2.4.3 and swig 2.0.2 The ALPHA_FS build was successful. I am using linux image provided by UT Austin. When I try to create checkpoint using : build/ALPHA_FS/gem5.opt configs/example/fs.py -n 3 --script=/home/sdhoble/parsecScripts/bodytrack_3c_simsmall_ckpts.rcS The terminal output is as follows : Global frequency set at 1000000000000 ticks per second info: kernel located at: /home/sdhoble/fullSystemImages/m5_system_2.0b3/binaries/vmlinux Listening for system connection on port 3456 0: system.tsunami.io.rtc: Real-time clock set to Thu Jan 1 00:00:00 2009 0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000 0: system.remote_gdb.listener: listening for remote gdb #1 on port 7001 0: system.remote_gdb.listener: listening for remote gdb #2 on port 7002 **** REAL SIMULATION **** info: Entering event queue @ 0. Starting simulation... info: Launching CPU 1 @ 170102500 info: Launching CPU 2 @ 172013000 warn: Prefetch instructions in Alpha do not do anything warn: Prefetch instructions in Alpha do not do anything hack: be nice to actually delete the event here Exiting @ tick 1871961237500 because m5_exit instruction encountered The document says that a pseudo-instruction in M5 creates the checkpoint. But the checkpoint is not created in the directory where the above command was run. To confirm this when I tried to run the actual benchmark using : build/ALPHA_FS/gem5.opt configs/example/fs.py --detailed --caches --l2cache --checkpoint-restore=1 -n 3 I get the following output : command line: build/ALPHA_FS/gem5.opt configs/example/fs.py --detailed --caches --l2cache --checkpoint-restore=1 -n 3 fatal: Checkpoint 1 not found Any help would be appreciated.
