SCore-D provides a multiple user, multiple parallel programming
environment. The name of SCore-D is generic, and there could be
several programs depending on scheduling policy, and so
on. A SCore-D program,
dqt, schedules user parallel
Distributed Queue Tree with that user parallel
processes are multiplexed in time and space domains. Another
tss, schedules user parallel processes
in a simple TSS fashion.
There are several peripheral programs supporting
dqt_monitor program is a server for monitoring
DQT load information.
sc_syslog program is also a server
for monitoring SCore-D load information.
To startup SCore-D environment on a cluster, follow the sequence:
dqt_monitoris a sequential (not a SCore-S/D program) for distributing
dqtload information for its client.
sc_syslogis also a sequential program for distributing SCore-D system information. Those programs can run on a host out of cluster.
tsson a cluster. Either program is runnable as an SCore-S program. Refer SCore User Manual for their SCore options. If
sc_sysloghave/has been invoked, corresponding option(s) described later must be given.
sc_sync are SCore-D applications.
SCore-D program is an SCore-D application to add a new SCore-D device
or remove an existing SCore-D device.
sc_sync SCore-D program
is an alternative of
update UNIX deamon
sc_sync synchronizes (flushs) i-node cache
periodically (30 sec interval).
tss are invoked, SCore-D server
host node that can accept users job submission is the host having
largest node number.
tss are SCore-S
programs. Thus they take normal SCore options described in SCore User Manual.
tss program accept following options:
sc_syslogis running and port number in
dqt_monitoris running and port number in
hostname[:portno]form. This option is only effective with
sc_shutdown shutdowns SCore-D.
-r option adds an SCore-D
device and invokes corresponding device server process and device
processes that are derived (forked) from the device server process on
the node specified by node_num option. The device name is
given by device_name option that is refered by user
programs. The device program invoked by SCore-D must be specified by
device_path and the device_path SHOULD be an
absolute path name. The specified program is assumed to be wriiten
accroding to SCore-D Device
Programming Manual. Arguments for device server invokation can
be followed by. With
sc_device tries to remove the device specified by
sc_syslog logs users' login and logout. Logging file can
be specified in command arguments. Default logging filename is
scored.mesg. Sending the
SIGHUP signal to
this daemon process, the program tries to reopen the logging file. If
-t option is specified, then the program simply output the
logging information to its standard output.
dqt_monitor is a daemon server for collecting scheduling
information of a DQT (Distributed Queue Tree).
sc_syslog program can take the following options;
There is a JAVA program to watch SCore-D user process status in real
time. And if this applet client is preferable, then the
sc_syslog program should run on a host where
httpd (HTTP daemon process) is
running. Otherwise, message board client applet can not establish a
