I was off at my local CompUSA last night playing with a new Sony VAIO 1.8 Ghz machine. It is _real_ nice: 512 MB RAM; 80 GB hdd; Nvidia 64 graphics; DVD R/W (!); CD R/W; 10/100 Ethernet; etc. All for $1799. This is a sweat machine to say the least. On top of that, Sony has a spectacular 18" LCD flat screen display that is to die for. re: VENDOR for Linux and FreeBSD is gcc/f2c > I kind of suspected that was the case. For a Buckeye, I show a lot of >Missourian traits, though. Must be why I'm a scientist. SSEC also includes Solaris x86 in the list of machines where VENDOR means gcc/f2c, but I change that since a number of my Solaris x86 sites have Sun compilers. re: What does 'top' show for memory use > Doing top results in 0K (as in zero K, not as in alright) for both my >linux (at home) and the SunUltra10 (at CofC).

As I recall from last year, the >sequence will be to install LDM and then LDM-MCIDAS. Right? The order doesn't matter. The key is to copy the ldm-mcidas decoders that you will be using (typically proftomd, nldn2md, pnga2area and batch.k) to a directory in 'ldm's PATH. I recommend use of ~ldm/decoders or ~ldm/util. A couple of McIDAS shell scripts will need to be copied to this directory as well (xcd_run, mcscour.sh, uwgrid.sh). > Going through the LDM directions, I changed all the /var/data >references to /export/home/mcdata as we discussed before. You said that >there was no longer a need for an ldm directory under ---/mcdata so I >didn't put one in there. The typical setup for the LDM is: o HOME in /usr/local o /usr/local/ldm/data is a link to a location where you have lots of disk. This could be /export/home/ldm/data in your case (new directory) o /usr/local/logs is a link to a location where you have lots of disk also. This could be /export/home/ldm/logs Creating the directories above separate from the McIDAS data (mcdata) directory is not mandatory, but it is advisable. >But now I'm reading the words in there about >the data having to go into an area that does not get backed. Is this >going to be a problem? The idea is that you agr going to be ingesting, decoding, and filing lots of data. If you put that data in a directory/on a file system that gets routine backup (every night; once a week), your backup proceedure will be _heavily_ used (read lots of tapes and human intervention to change those tapes). Since data can be gotten from remote machines from archives, why "archive" (backup) the data yourself. Now, a number of sites what their own archive. If you fall into this category, then disregard the comments above. >Should I proceed to put the ldm data in >/export/home/mcdata? I recommend: /export/home/ldm /export/home/ldm/data /export/home/ldm/logs /export/home/mcdata /export/home/gempak ... >If I do, should we exclude that directory from the >backup list? It would be a good idea, but remember that you are going to be dealing with LOTS of data (GBs/day). >Since we don't have an AIX OS, we don't have to worry >about the data getting scrambled every Sunday morning, ??? Our AIX sites don't complain about this... >I reckon. If I >do proceed as we discussed earlier, then of course the symbolic links >in ~ldm/data and ~ldm/logs would change accordingly.
