I hope this is a proper mailing list for my problem. If not - please redirect me. I have written a piece of simulation software in C++ that relies heavily on the Accelerate framework - in particular the BLAS implementation. The software is compiled for the ppc64 architecture, i.e. 64 bit. I can control how much memory the program uses, but needless to say - the more of my main memory I allow it too use, the faster the BLAS routines run due to the internal threading used in the library. The problem is that if I let the program use 6-7 GB out of my total of 8 GB, the machine will eventually crash (see an example of a crash- dump below. The cpu causing the panic varies from time to time). Note that the machine is not swapping when these crashes occur. Now, I would be willing to blame this on bad memory, but the machine runs weeks on end performing other heavy computational tasks (although in 32-bit mode). The same problem also occurs on a separate dual G5 with 8 GB of memory. So - do anyone have any opinions on what might be going on here? Is it a hardware problem (occuring on both machines), can it be a problem with my software (same setup runs fine on a dual Opteron machine with 8 GB of memory), or is it a problem with OS X/Darwin? panic(cpu 2 caller 0x000A8D80): Uncorrectable machine check: pc = FFFFFFFFFFFF8260, msr = 900000000004F030, dsisr = 00200000, dar = 00000000B0011C00 AsyncSrc = 0000000000000000, CoreFIR = 0000000000000000 L2FIR = 0000000000000000, BusFir = 0000000000000000 Latest stack backtrace for cpu 2: Backtrace: 0x00095718 0x00095C30 0x0002683C 0x000A8D80 0x000A84C8 0x000ABD00 Proceeding back via exception chain: Exception state (sv=0x5849D780) PC=0xFFFF8260; MSR=0x0004F030; DAR=0xB0011C00; DSISR=0x00200000; LR=0x00845194; R1=0x8AD13BB0; XCP=0x00000008 (0x200 - Machine check) Kernel version: Darwin Kernel Version 8.4.0: Tue Jan 3 18:22:10 PST 2006; root:xnu-792.6.56.obj~1/RELEASE_PPCModel: PowerMac11,2, BootROM 5.2.7f1, 4 processors, PowerPC G5 (1.1), 2.5 GHz, 8 GB Graphics: NVIDIA GeForce 6600, GeForce 6600, PCI, 256 MB Memory Module: DIMM0/J6700, 1 GB, DDR2 SDRAM ECC, PC2-4200E-444 Memory Module: DIMM1/J6800, 1 GB, DDR2 SDRAM ECC, PC2-4200E-444 Memory Module: DIMM2/J6900, 1 GB, DDR2 SDRAM ECC, PC2-4200E-444 Memory Module: DIMM3/J7000, 1 GB, DDR2 SDRAM ECC, PC2-4200E-444 Memory Module: DIMM4/J7100, 1 GB, DDR2 SDRAM ECC, PC2-4200E-444 Memory Module: DIMM5/J7200, 1 GB, DDR2 SDRAM ECC, PC2-4200E-444 Memory Module: DIMM6/J7300, 1 GB, DDR2 SDRAM ECC, PC2-4200E-444 Memory Module: DIMM7/J7400, 1 GB, DDR2 SDRAM ECC, PC2-4200E-444 Network Service: Innebygd Ethernet 1, Ethernet, en0 PCI Card: GeForce 6600, Display, SLOT-1 PCI Card: bcom5714, network, GIGE PCI Card: bcom5714, network, GIGE Serial ATA Device: Hitachi HDS725050KLA360, 465.76 GB Parallel ATA Device: HL-DT-ST DVD-RW GWA-4165B, USB Device: Hub in Apple Pro Keyboard, Mitsumi Electric, Up to 12 Mb/ sec, 500 mA USB Device: Apple Pro Keyboard, Mitsumi Electric, Up to 12 Mb/sec, 250 mA FireWire Device: unknown_device, unknown_value, Up to 400 Mb/sec This email sent to site_archiver@lists.apple.com
