Hi all, Could anyone inform me the way to configure more than 1GB physical memory on ALPHA_FS machine?
The ALPHA_FS works quite well when I configure 1GB memory on configs/common/Benchmarks.py. However, when I modify the line 49 of Benchmark.py to "return '2GB'", my gem5 aborts simulation during booting process with following error messages. $ build/ALPHA_FS/gem5.fast configs/example/fs.py gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 compiled Mar 28 2012 22:37:29 gem5 started Apr 18 2012 16:50:01 gem5 executing on apollon command line: build/ALPHA_FS/gem5.fast configs/example/fs.py Global frequency set at 1000000000000 ticks per second info: kernel located at: /cal/home/seongil/simulators/gem5/test/gem5-test/dist/alpha/binaries/vmlinux Listening for system connection on port 3456 0: system.remote_gdb.listener: listening for remote gdb on port 7000 **** REAL SIMULATION **** info: Entering event queue @ 0.
