One can get hold of some pretty impressive horse power these days — cpu core
count and massive system RAM.
I have experimental access to one such and am wanting to test batch submission
of forecast maps to see just what I can get away with. Could I get 20 gdplot2
jobs of 20 gfs forecast hours running on 20 cores simultaneously?
I think I’m asking what’s a good way to submit gdplot2 image production in the
background?
eg., if I currently plot GFS 250mb height, winds, and isotaches by running each
forecast hour successively with:
————
#!/bin/csh
# restore file gfs.215.nts has appropriate GDFILE specification
foreach fcst ( `seq -w 000 006 120` )
set outfile = 250wnd_gfs_f${fcst}.gif
gdplot2<<END_INPUT
restore gfs.215.nts
GDATTIM = f${fcst}
\$MAPFIL = TPPOWO.GSF
GLEVEL = 250
GVCORD = pres
GDPFUN = knts(mag(wnd)) ! hght ! kntv(wnd)
CINT = ! 120 !
TITLE = 31/-3/GFS FORECAST INIT ^ ! 31/-2/${fcst}-HR FCST VALID ?~ !
31/-1/250-HPA HEIGHTS, WINDS, ISOTACHS (KT)
DEVICE = GIF|$outfile|1880;1010
FINT = 70;90;110;130;150;170
FLINE = 0;5;10;17;13;15;30
TYPE = f ! c ! b
r
exit
END_INPUT
gpend
end
————
how could I modify this effort to submit each forecast hour job simultaneously
onto the system?
And I’m not averse to bash shell. If it’s much easier with bash, I’ll take any
suggestions.
