Re: SCHED_ULE should not be the default

My code is a classic master-slave OpenMPI application where the master runs on one node and all cpu-bound slaves are sent to a second node. If I send send ncpu+1 jobs to the 2nd node with ncpu's, then ncpu-1 jobs are assigned to the 1st ncpu-1 cpus. The last two jobs are assigned to the ncpu'th cpu, and these ping-pong on the this cpu. AFAICT, it is a cpu affinity issue, where ULE is trying to keep each job associated with its initially assigned cpu. While one might suggest that starting ncpu+1 jobs is not prudent, my example is just that. It is an example showing that ULE has performance issues. So, I now can start only ncpu jobs on each node in the cluster and send emails to all other users to not use those node, or use 4BSD and not worry about loading issues. Does it meet your expectations if you start (j modulo ncpu) = 0 jobs on a node? -- Scott LambertKC5MLE Unix SysAdmin lamb...@lambertfam.org ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

ACPI testing/debugging guide?
Is there some list of actions to preform and data to collect that would assist with getting the ACPI stuff lined out? I've read the acpiconf man page but don't know that it gives me any way to test for any specific functionality. I've been gradually piecing together the meaning of S1, S2, S3, S4, and S5 and figuring out that the *_(button|switch)_state sysctl oids specify which state to go to on activation of that button rather than being a descriptor of the current state of the buttons. I haven't figured out if the hw.acpi.thermal oids. I think maybe ACPI doesn't recognize the hardware. Is a thermal oid value of 3692 actually 36.92 celcius or some scale from 0x to 0x? Is battery.time supposed to be -1 when on AC? My resume from suspend doesn't work and I don't know how to tell where that is going wrong. I have no serial interface so I can't use a serial console when the LCD doesn't come on. I can live without suspend/resume functionality. You can't miss something you have never had. :-) I would like to be able to tell the fan to stay on anytime it has AC power since it is gradually cooking my lap.
