Does anybody know of a good alternative to Sun Grid Engine? It seems that Oracle is now charging for this software. I am running a HPC cluster that has Solaris 10 machines and I am adding some nodes that will be running Ubuntu 10.04, eventually the Solaris machines will be migrating to Ubuntu.
Hi,
I was trying to run a program that calls 8 processors (with max. RAM of 2 GB per processor). I want to run this program on my cluster that runs SGE. The cluster has 2 nodes, and each node has 62 cores, and 248GB/node. Currently, I use the scripts below, but the program (softx below) crashes... (0 Replies)

Hello all,
I was wondering if someone could either explain or maybe point me to another article somewhere that explains the difference between:
distributed computing
grid computing
parallel computing
I see these terms thrown around a lot in server and cluster environments, but I'd like a... (2 Replies)
Hi forum,
I am aware that on Hp-Superdome technology (Blade Servers) is avaliable while on Solaris GRID technology is the latest in the market. I would like to know if similar high end technology is also available for AIX ? (1 Reply)
Hi everybody:
I want to create a grid file for export to statistical program.
My aid is create a file with both rows, one row are x coordenates and other for y coordenates.
All grid obviousolly are same space.
the form that i want is this:

SGE_SHADOWD(8) Sun Grid Engine Administrative Commands SGE_SHADOWD(8)NAME
sge_shadowd - Sun Grid Engine shadow master daemon
SYNOPSIS
sge_shadowd
DESCRIPTION
sge_shadowd is a "light weight" process which can be run on so-called shadow master hosts in a Sun Grid Engine cluster to detect failure of
the current Sun Grid Engine master daemon, sge_qmaster(8), and to start-up a new sge_qmaster(8) on the host on which the sge_shadowd runs.
If multiple shadow daemons are active in a cluster, they run a protocol which ensures that only one of them will start-up a new master dae-
mon.
The hosts suitable for being used as shadow master hosts must have shared root read/write access to the directory $SGE_ROOT/$SGE_CELL/com-
mon as well as to the master daemon spool directory (by default $SGE_ROOT/$SGE_CELL/spool/qmaster). The names of the shadow master hosts
need to be contained in the file $SGE_ROOT/$xQS_NAME_Sxx_CELL/common/shadow_masters.
RESTRICTIONS
sge_shadowd may only be started by root.
ENVIRONMENT VARIABLES
SGE_ROOT Specifies the location of the Sun Grid Engine standard configuration files.
SGE_CELL If set, specifies the default Sun Grid Engine cell. To address a Sun Grid Engine cell sge_shadowd uses (in the order of
precedence):
The name of the cell specified in the environment variable SGE_CELL, if it is set.
The name of the default cell, i.e. default.
SGE_DEBUG_LEVEL
If set, specifies that debug information should be written to stderr. In addition the level of detail in which debug infor-
mation is generated is defined.
SGE_QMASTER_PORT
If set, specifies the tcp port on which sge_qmaster(8) is expected to listen for communication requests. Most installations
will use a services map entry for the service "sge_qmaster" instead to define that port.
SGE_DELAY_TIME This variable controls the interval in which sge_shadowd pauses if a takeover bid fails. This value is used only when there
are multiple sge_shadowd instances and they are contending to be the master. The default is 600 seconds.
SGE_CHECK_INTERVAL
This variable controls the interval in which the sge_shadowd checks the heartbeat file (60 seconds by default).
SGE_GET_ACTIVE_INTERVAL
This variable controls the interval when a sge_shadowd instance tries to take over when the heartbeat file has not changed.
FILES
<sge_root>/<cell>/common
Default configuration directory
<sge_root>/<cell>/common/shadow_masters
Shadow master hostname file.
<sge_root>/<cell>/spool/qmaster
Default master daemon spool directory
<sge_root>/<cell>/spool/qmaster/heartbeat
The heartbeat file.
