Background:
I use a bash shell to parallel pocess pov files with cluster.I install the
povray with user level.as this
post(http://news.povray.org/povray.unix/thread/%3Cweb.427b7d35341b56bfac3379a40@news.povray.org%3E/)
said:/usr/local/etc/povray/3.6/povray.conf: No such file or directory"
will not be harmless.But I met this problem
------------------------------------------------------------------
Problem:
this is a part of my shell:
.................
#POVRAY process each pov files into png files
cluster-fork --bg -n "compute-0-%d:0-5"
/home/cfd/soft/jakarta-tomcat-5.5.4/webapps/particle/script/4thpovray.sh
"$1"pov/ 5 >>logPov
ray.txt
echo the next step is to make the animation!
#ImageMagick Usage:convert this png files to an animation
convert -delay 20  "$1"pov/*.png "$1"gif/animation.gif
..................

when I render this bash file 1st time,there is no gif files in the
directory.
but when I render it again,the gif I wanted was built.
I was puzzled,so I delete all the temp files and render it once more,this
time the gif file built correctly.I repeat several times,I fould it is
unpredicted when the destination files can be built correctly.
--------------------------------------------------------------------------
suspect:
1.the User lever installation problem? when I run the script,with
promot:/usr/local/etc/povray/3.6/povray.conf: No such file or directory"/
but I don't have the privilege to test with root.
2.not rubust in parallel enviroment.is there similar problem found before?
3.something wrong with animation making(convert png to gif)?

what is your suggestion?
thank you every much
