Dear All, I am trying to run FFT benchmark on GEM5 with Ruby. I was not able to run it with 16 cores although I was using BigTsunami with the patched PAL code. I guess the problem with the memory size (was set to 512MB) which I had to increase to 2047MB (2048MB was resulting in overflow in simulator memory size). Now the simulator could bring up 16 cores to work but while booting the linux kernel, the process hangs when reaching "SCSI initialization". I never could complete the kernel boot operation. Here is what I get on the system.terminal ------------------------------------------------------------------------------------- M5 console: m5AlphaAccess @ 0xFFFFFD0200000000 Got Configuration 623 memsize 7FF00000 pages 3FF80 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 = 0x10 CPU Clock at 2000 MHz IntrClockFrequency=1024 Booting with 16 processor(s) KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 KSP: 0x20043FE8 PTBR 0x20 Console Callback at 0x0, fixup at 0x0, crb offset: 0x2A90 Memory cluster 0 [0 - 392] Memory cluster 1 [392 - 261624] Initalizing mdt_bitmap addr 0xFFFFFC0000038000 mem_pages 3FF80 ConsoleDispatch at virt 10002BD8 phys 1ABD8 val FFFFFC00000100A8 Bootstraping CPU 1 with sp=0xFFFFFC0000076000 Bootstraping CPU 2 with sp=0xFFFFFC0000078000 Bootstraping CPU 3 with sp=0xFFFFFC000007A000 Bootstraping CPU 4 with sp=0xFFFFFC000007C000 Bootstraping CPU 5 with sp=0xFFFFFC000007E000 Bootstraping CPU 6 with sp=0xFFFFFC0000080000 Bootstraping CPU 7 with sp=0xFFFFFC0000082000 Bootstraping CPU 8 with sp=0xFFFFFC0000084000 Bootstraping CPU 9 with sp=0xFFFFFC0000086000 Bootstraping CPU 10 with sp=0xFFFFFC0000088000 Bootstraping CPU 11 with sp=0xFFFFFC000008A000 Bootstraping CPU 12 with sp=0xFFFFFC000008C000 Bootstraping CPU 13 with sp=0xFFFFFC000008E000 Entering slaveloop for cpu 6 my_rpb=FFFFFC0000019080 Entering slaveloop for cpu 8 my_rpb=FFFFFC0000019580 Bootstraping CPU 14 with sp=0xFFFFFC0000090000 Entering slaveloop for cpu 4 my_rpb=FFFFFC0000018B80 Entering slaveloop for cpu 5 my_rpb=FFFFFC0000018E00 Entering slaveloop for cpu 12 my_rpb=FFFFFC0000019F80 Entering slaveloop for cpu 9 my_rpb=FFFFFC0000019800 Entering slaveloop for cpu 10 my_rpb=FFFFFC0000019A80 Bootstraping CPU 15 with sp=0xFFFFFC0000092000 Entering slaveloop for cpu 2 my_rpb=FFFFFC0000018680 Entering slaveloop for cpu 7 my_rpb=FFFFFC0000019300 Entering slaveloop for cpu 15 my_rpb=FFFFFC000001A700 Entering slaveloop for cpu 1 my_rpb=FFFFFC0000018400 Entering slaveloop for cpu 14 my_rpb=FFFFFC000001A480 Entering slaveloop for cpu 13 my_rpb=FFFFFC000001A200 unix_boot_mem ends at FFFFFC0000094000 Entering slaveloop for cpu 3 my_rpb=FFFFFC0000018900 k_argc = 0 Entering slaveloop for cpu 11 my_rpb=FFFFFC0000019D00
