I diagnosed the problem. I gave a fairly easy method for reproducing the problem (including providing a statically linked MPI program, and a script and data files to launch it). I offered access to one of the nodes in my cluster (including root access to install new kernels and to reboot the node).

Of course, having no experience in processing scheduling, I don't understand the question either ;-) AFAICT, it is a cpu affinity issue. If I launch n+1 MPI images on a system with n cpus/cores, then 2 (and sometimes 3) images are stuck on a cpu and those 2 (or 3) images ping-pong on that cpu.

Disabling ssh timeouts?
Is there anyway to disable sshd from timing out a connection? I've tried setting ClientAliveCountMax and ClientAliveInterval and TCPKeepAlive in sshd.conf, but no combination that I've tried has worked. I'm trying to running the GCC testsuite, which is not an interactive job. Once it starts, it writes to stdout when an error occurs or the testsuite moves to a new major test category. The last few lines of output are Running target unix Using /usr/X11R6/share/dejagnu/baseboards/unix.exp as board description file for target. Using /usr/X11R6/share/dejagnu/config/unix.exp as generic interface file for target. Using /usr/home/sgk/gcc/gcc4x/gcc/testsuite/config/default.exp as tool-and-target-specific interface file.

Thanks for the reply. Perhaps, I'm missing an important detail, but gmirror(8) seems to suggest that it operates on an entire disk. Note, in my original email I used the word partition but showed a disk slice. I really do mean a partition within a slice.

Method to mirror a single partition across the net.

I don't see how this is convoluted. In fact, I would be inclined to claim that it is the defacto method for setting up an internal computational cluster s <---> node1 internet <-F-> FQDN|master <---> w <---> node2 t <---> node3 where swt = switch. > It is not normally desirable to set up a YP/NIS master server on > a machine which is multihomed in the sense of doing NAT or needing > a firewall to separate internal from external, and obvious a > firewall machine running zero or the minimal necessary services is > a lot more secure Note that <-F-> actually has at least one firewall. Only people in the apl.washington.edu domain can get to FQDN. I was hoping to use NIS to simplify the propagation of info (eg., passwd, hosts, etc.) from master to the nodes. Propagating the info by hand isn't too bad because I only have five nodes represently. However, I hope to grow an additional 11 nodes. -- Steve ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

It unconditionally uses /bin/hostname, which will grab the FQDN of the system. You have given me an idea. I can change rc.conf to set hostname to the name I've given 192.168.0.10, put that on bge0, put the IP address associated with the FQDN on bge1, and reboot. This might permit NIS to come up. Though this seems like a hack, because when someone connects to the seem via the FQDN, /bin/hostname will give the wrong answer. -- Steve ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Setting up NIS questions?
I have 2 NICS in the master node of a small cluster. bge0 is connected to the outside world with a FQDN and registered DNS IP address. bge1 is connected to a 192.168.0.x internal network. I'm trying to configure NIS for the internal network, but ypinit is grabbing the FQDN. I've read the Handbook and ypinit manual page without too much enlightment. :( What I'm after is 192.168.0.10 NIS master server 192.168.0.11 NIS slave server 192.168.0.[12-15] NIS clients Anyone have a pointer to a method to achieve my goals. -- Steve ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

The above partially solved out problem. My colleague would like to use the US keyboard layout and switch to a Danish layout when he's interacting with someone back home.

Setting up a danish locale
Problem: We have a visiting scientist from Denmark, whose laptop died a horrible death. A colleagued asked if I would loan him a currently unused system in my office. I've set up FreeBSD 5.3 on the system and everything appears to work except for setting up a Danish locale. Disclaimer: I searched the Handbook, used google, and spent a few hours reading up of login.conf, locale support, etc. But, we are stuck without the danish locale. I have setup a ~/,login_conf in the user home directory that contains dhcp-78-77:kargl[201] cat .login_conf me:\ :charset=ISO8859-1:\ :lang=da_DK.ISO8859-1: When we login, we see that the locale is set dhcp-78-77:kargl[202] locale LANG=da_DK.ISO8859-1 LC_CTYPE="da_DK.ISO8859-1" LC_COLLATE="da_DK.ISO8859-1" LC_TIME="da_DK.ISO8859-1" LC_NUMERIC="da_DK.ISO8859-1" LC_MONETARY="da_DK.ISO8859-1" LC_MESSAGES="da_DK.ISO8859-1" LC_ALL= But any attempt to enter a danish character in for examples xemacs fails. From my colleagues comment a "Right-Alt / o" should yield a lower case "o" with a slash through it. His system is running Xorg 6.7.0_9. I suspect that I need to change/update his xorg.conf file.
