Dear gem5-users, I have designed a new prefetcher and I have run it on gem5 ALPHA ISA for blackscholes. I am dynamically updating prefetch degree and printing it whenever its updated.
I am trying to create checkpoints for blacksholes using the following command: ./build/ALPHA/gem5.opt ./configs/example/fs.py --cpu-type=detailed --caches --l2cache --l2_size=512kB --script=./m5parsec/blackscholes_4c_simsmall.rcS --kernel=vmlinux --disk-image=linux-latest.img --take-checkpoints=10000000000,5000000000 --checkpoint-dir=/home/prasanth/gem5/m5out/checkpoints/blackscholes_simsmall/ I can see the output printed in the terminal until the real simulation started but after that there are no entries in the terminal. Also the terminal on port 3456 halted after printing the following: prasanth@prasanth-VPCCB15FG:~$ telnet localhost 3456 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. ==== m5 slave terminal: Terminal 0 ==== M5 console: m5AlphaAccess @ 0xFFFFFD0200000000 Got Configuration 623 memsize 20000000 pages 10000 First free page after ROM 0xFFFFFC0000018000 HWRPB 0xFFFFFC0000018000 l1pt 0xFFFFFC0000040000 l2pt 0xFFFFFC0000042000 l3pt_rpb 0xFFFFFC0000044000 l3pt_kernel 0xFFFFFC0000048000 l2reserv 0xFFFFFC0000046000 kstart = 0xFFFFFC0000310000, kend = 0xFFFFFC0000899860, kentry = 0xFFFFFC0000310000, numCPUs = 0x1 CPU Clock at 2000 MHz IntrClockFrequency=1024 Booting with 1 processor(s) KSP: 0x20043FE8 PTBR 0x20 Console Callback at 0x0, fixup at 0x0, crb offset: 0x510 Memory cluster 0 [0 - 392] Memory cluster 1 [392 - 65144] Initalizing mdt_bitmap addr 0xFFFFFC0000038000 mem_pages 10000 ConsoleDispatch at virt 10000658 phys 18658 val FFFFFC00000100A8 unix_boot_mem ends at FFFFFC0000076000 k_argc = 0 jumping to kernel at 0xFFFFFC0000310000, (PCBB 0xFFFFFC0000018180 pfn 1101) CallbackFixup 0 18000, t7=FFFFFC0000814000 Linux version 2.6.27.6-dirty (joel@capillary) (gcc version 4.3.4 (crosstool-NG-1.5.2) ) #1 SMP Sat Mar 6 19:10:44 CST 2010 Booting GENERIC on Tsunami variation DP264 using machine vector DP264 from SRM Major Options: SMP LEGACY_START VERBOSE_MCHECK Command line: root=/dev/hda1 console=ttyS0 memcluster 0, usage 1, start 0, end 392 memcluster 1, usage 0, start 392, end 65536 freeing pages 1103:65536 reserving pages 1103:1104 SMP: 1 CPUs probed -- cpu_present_map = 1 Built 1 zonelists in Zone order, mobility grouping on.
