|
|
The QTDIR -environment variable has to be set to your QT-installation
|
|
directories like it is well described in the INSTALL- file.
|
|
In versions < 0.6 you can do a "make clean" and delete the two files:
|
|
/openmosixview/Makefile
|
|
/openmosixview/config.cache
|
|
and try to compile again because i alway left the binary-
|
|
and object-files in older versions.
|
|
If you have any other problems post them to the
|
|
openMosixview-mailinglist (or directly to me). </P

You have to be able to ssh to each node in your cluster without password
|
|
(just like the same with using RSH this is required) </P

Do not fork openMosixview in the background with & (e.g. openMosixview &).
|
|
Maybe you cannot rsh/ssh (depends on what you want to use) as user root
|
|
without password to each node?
|
|
Try "rsh hostname" as root. You should not been promped for a password
|
|
but soon get a login shell.
|
|
(If you use SSH try "ssh hostname" as root.)
|
|
You have to be root on the cluster because that is the only way the
|
|
administrative commands executed by openMosixview requires root-privileges.
|
|
openMosixview uses "rsh" as the default!
|
|
If you only have "ssh" installed on your cluster
|
|
edit (or create) the file /root/.openMosixview and put "1111" in it.
|
|
This is the main-configuration
|
|
file for openMosixview and the last "1" stands for "use ssh instead of rsh".
|
|
This will cause openMosixview to use "ssh" even for the first start. </P

The openMosixview-client is executed per rsh
|
|
(or ssh which you can configer whith a checkbox)
|
|
on the remote host. It has to be installed in /usr/bin/ on each node.
|
|
If you use RSH try:
|
|
"xhost +hostname"
|
|
"rsh hostname /usr/bin/openMosixview_client -display your_local_host_name:0.0"
|
|
or if you use SSH try:
|
|
"xhost +hostname"
|
|
"ssh hostname /usr/bin/openMosixview_client -display your_local_host_name:0.0"
|
|
If this works it will work in openMosixview too.
|
|
openMosixview crashes with "segmentation fault"!
|
|
Maybe you still use an old version of openMosixview/Mosixview ?
|
|
in the mosix.map-parser (which is completly removed in openMosixview !!)
|
|
(the versions openMosixview 1.2 and Mosixview > 1.0 are stable) </P

(automigration on/off, blocking on/off......)
|
|
I want them to be preselected too.
|
|
|
|
The problem is to get the information of node.
|
|
You have to login to each cluster-node because these information
|
|
are not cluster-wide (to my mind).
|
|
The status of each node is stored in the /proc/hpc/admin directory
|
|
of each node. Everybody who knows a good way to get these information
|
|
easy is invited to mail me.
