I Must Be Doing Something Right

I know I’m being pro­duc­tive when my hard dri­ve runs out of space. 

Open Stu­dios is hap­pen­ing in anoth­er month and a half, and I don’t have any­where near as much work ready as I’d like. Get­ting prints made and framed requires a bit of lead time, so it’s not just a mat­ter of get­ting more ink down on paper. My dead­lines are draw­ing very very near. You can eas­i­ly imag­ine how frus­trat­ing it is then to have my machines show me their lim­i­ta­tions. Yet at the same time, run­ning up against the lim­its of my devices means I’m push­ing the lim­its of what’s pos­si­ble, at least on some level.

Tonight as I was edit­ing a file in Pho­to­shop, I got an error mes­sage I haven’t seen in some time. When I attempt­ed to cre­ate a sec­ond lay­er in the file I’m work­ing on, I was told that the oper­a­tion can­not be com­plet­ed because my scratch disks are full.

I hes­i­tate to even won­der what my vir­tu­al mem­o­ry files look like right now, but clear­ly I need to free up some space. I’m work­ing on a hand-built screen for a large-for­mat lux­o­graph­ic. What that means is that I’ll be over­lay­ing a hand-drawn (or at least hand-mod­i­fied in this case) pat­tern over the indi­vid­ual chan­nels of a col­or-sep­a­rat­ed pho­to­graph to cre­ate an organ­ic ver­sion of a halftone screen. Or in even sim­pler terms, I’ll be mak­ing a pic­ture from a col­lec­tion of lines.

Since I won’t be let­ting an image proces­sor do the work of build­ing those lines, I have to cre­ate an image at the res­o­lu­tion of my out­put device. Since I’m cre­at­ing an image near­ly six feet wide, that’s a lot of pix­els. Since even that does­n’t give me enough res­o­lu­tion to cre­ate the illu­sion of smooth col­or tran­si­tions, I have to over­sam­ple the orig­i­nal image, apply the screens, and then down­sam­ple to end up with antialiased lines to be used as screens.

The upshot is that the file I’m work­ing with right now, which con­tains only one of four col­or chan­nels, is a four giga­byte file. When I save my changes to the file, I can get up and go make cof­fee and come back to find the file still sav­ing. Believe me, those quad-proces­sor machines are look­ing real­ly tempt­ing these days. Unfor­tu­nate­ly, the last time I spec’ed out a com­put­er for myself, the total came to twen­ty thou­sand dol­lars. That’s about nine­teen thou­sand, nine hun­dred and nine­ty-eight more dol­lars than I have in my wal­let right now.

Still, it gives me a small feel­ing of pride to know that I’m tax­ing my com­put­ers so heav­i­ly. I sup­pose if cre­at­ing large pieces of art­work was easy, every­one would be doing it, right? So I real­ly don’t feel all that frus­trat­ed as I back files up to DVDs to clear off space from my hard dri­ve. The only thing that real­ly both­ers me is that I’m attempt­ing some­thing that I don’t know will work. If it does, I’ll have three more chan­nels to work with. If it does­n’t, I get to start over look­ing at how to approach this piece.

Yes, we are hav­ing fun yet.

  1. What are you spec’ing that
    What are you spec’ing that costs 20 grand? And would you get more than a 2% increase in per­for­mance over a 5K machine? Or 20% over a $500 box?

    Just curi­ous. I know Macs are expen­sive, but.….

    1. The twen­ty grand sys­tem
      The twen­ty grand sys­tem looks like this:

      Two 3.2GHz Quad-Core Intel Xeon (8‑core)
      32GB (84GB)
      Mac Pro RAID Card
      Two 300GB 15,000-rpm SAS drives
      1TB 7200-rpm Ser­i­al ATA 3Gb/s
      NVIDIA Quadro FX 5600 1.5GB (Stereo 3D, two dual-link DVI)
      Apple Cin­e­ma HD Dis­play (30″ flat panel)

      See? I’m not even get­ting two dis­plays! Eco­nom­i­cal! *koff koff*

      OK, I can take a more rea­son­able approach here. The price dif­fer­ence between dual 2.8GHz quad-core Xeons and dual 3.2GHz quad-code Xeons is $2100. Con­sid­er­ing that that’s a measly 14% bump in per­for­mance where the proces­sor is not my bot­tle­neck, the 2.8s are prob­a­bly a smarter choice.

      In the real world, Even the NVIDIA GeForce 8800 GT 512MB video card is more than I need. Since it’s $2650 less than the one I spec’d, I sup­pose that’s more realistic.

      The real killer in the price is the 32GB of 800MHz DDR2 ful­ly buffered ECC RAM which Apple charges nine thou­sand dol­lars for. I could get that RAM from Oth­er­World Com­put­ing for six thou­sand dol­lars less (still made to Apple’s ther­mal specs) and install it myself.

      So with those small con­ces­sions that would result in neg­li­gi­ble loss of per­for­mance, I’ve turned this into a $10,500 workstation.

      The next finan­cial hit there is the RAID card with those 15,000 RPM SAS dri­ves. My think­ing there is that one of those dri­ves is the sys­tem dri­ve, and the oth­er would be exclu­sive­ly for Pho­to­shop scratch disc usage. All my files can go on that 7200 RPM ATA dri­ve. This set­up is $2400 more than the ter­abyte ATA dri­ve alone, which makes it a tempt­ing tar­get for elim­i­na­tion, but the speed of my hard dri­ves is def­i­nite­ly a real per­for­mance bot­tle­neck. Since at this point I’m dream­ing even to think about a $500 com­put­er, I may as well dream with the fea­tures that will affect per­for­mance on the kinds of tasks I do.

      I’ve writ­ten this entire response in the time it’s tak­en from Pho­to­shop’s Fill com­mand progress bar dis­ap­pear­ing to show­ing the change on half the image on the screen. (I’m writ­ing on the lap­top and watch­ing the squares of pat­tern fill in on the desk­top machine). Assum­ing the bot­tle­neck in per­for­mance is almost entire­ly in the spool­ing to the scratch disk, I’m guess­ing off the top of my head that if I had that $10,500 to spend it would turn three hours of wait­ing into one on a file like this.
