Subject: Re: sol architecture startup error
Date: Mon, 13 Aug 2001 14:09:33 -0600

The Ultra architecture is different from that of earlier SUN models.
It is possible to compile and link for generic SUN machines for for
Ultra-only.  That is the real difference between to SOL and SUL
"architectures" in AIPS.  The actual performance difference seems to
be small.  But non-Ultras cannnot execute code build for use only by
Ultras.  If you seriously need to use the old machines, you could
rebuild for SOL:

edit HOSTS.LIST to make your machine a SOL
cd $AIPS_ROOT
./LOGIN.SH
$CDTST
cd $TST
mv SOL SOLold
mv SUL SOL
cd SOL.LIBR
rm */SUBLIB
cd ../INSTALL
rm *.LIS *.LOG*.ERR
( INSTEP2 >/dev/null 2>>INSTEP2.ERR & )

     when done

( INSTEP4 >/dev/null 2>>INSTEP4.ERR & )

We use SOL for non-Ultras and the older Ultras that do not have much
memory and we build the AP at 5 Megabytes.  For he bigger Ultras, we
use SUL with a 20 Megabyte AP.
