Hi, I'm running into a deadlock problem for running Ruby for 32 cores or more. The error message is as follows: "build/ALPHA_FS_MOESI_CMP_directory/m5.opt -d ruby_opt/ --trace-flags=Exec configs/example/ruby_fs.py -b fft_64t_base -n 32 warn: Prefetch instrutions is Alpha do not do anything For more information see: http://www.m5sim.org/warn/3e0eccba warn: Prefetch instrutions is Alpha do not do anything For more information see: http://www.m5sim.org/warn/3e0eccba panic: Possible Deadlock detected. Aborting! version: 0 request.paddr: 0x18c3b80 m_readRequestTable: 1 current time: 560855347 issue_time: 542870667 difference: 17984680 @ cycle 280427673500 [wakeup:build/ALPHA_FS_MOESI_CMP_directory/mem/ruby/system/Sequencer.cc, line 107] Memory Usage: 2476704 KBytes For more information see: http://www.m5sim.org/panic/ee664ab2 Program aborted at cycle 280427673500"
One of my big problems is that it appears that Ruby is keeping a different time then the actual system time? For instance it states the issue starts at current time "542870667" but the error aborts at tick "280427673500". Have any of the Ruby people seen this and think it's a issue in terms of keeping time consistent across cores? The actual console output I get to and hang at is: "M5 console: m5AlphaAccess @ 0xFFFFFD0200000000 Got Configuration 623 memsize 80000000 pages 40000 First free page after ROM 0xFFFFFC0000018000 HWRPB 0xFFFFFC0000018000 l1pt 0xFFFFFC0000040000 l2pt 0xFFFFFC0000042000 l3pt_rpb 0xFFFFFC0000044000 l3pt_kernel 0xFFFFFC0000048000 l2reserv 0xFFFFFC0000046000 kstart = 0xFFFFFC0000310000, kend = 0xFFFFFC00008964E0, kentry = 0xFFFFFC0000310000, numCPUs = 0x20 CPU Clock at 2000 MHz IntrClockFrequency=1024 Booting with 32 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 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: 0x5290 Memory cluster 0 [0 -
