I'm currently running Alpha FS with 64 cores without any noticeable problems. I'm using the tsb_osfpal PAL binary and Linux v2.6.18. But, I am not booting the kernel in atomic mode. I use timing mode with simple CPUs to run experiments and boot the OS, which may not be compatible with the experiments you're running.

Hi all, I am trying to scale a cluster design to use 32 and 64 cores, but when I fast-forward in atomic mode to get to the simulation point, I notice that linux tries to launch all the CPUs up to 63, and then I get: "smp_call_function_on_cpu: initial timeout -- trying long wait"at which point linux appears to be waiting for some response and the simulation waits. Has anyone successfully boot 32 or 64 cores in full system alpha without experiencing this delightful event? If so, what kernel and palcode did you use? Thanks in advance, Rick _______________________________________________ m5-users mailing list [email protected] http://m5sim.org/cgi-bin/mailman/listinfo/m5-users No virus found in this incoming message.
