CopperSpice Experiments – Pt. 6

Sorry I haven’t written in a while. Life has been busy and I’ve been hacking away at Diamond in my “spare” time. I guess I need to catch this post series up.

I used GitKraken to clone the repository into ~/Projects/diamond. Then I created ~/Projects/diamond_build and ~/Projects/diamond_debug. Diamond had an additional dependency of hunspell.

sudo apt install libhunspell-dev

After that it was time to build. Change to the build directory and type the following:

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=../diamond_debug -DCMAKE_PREFIX_PATH=/usr/lib/cs_lib/lib/cmake/CopperSpice ../diamond
roland@roland-amd-desktop:~/Projects/diamond_build$ cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/usr/lib/cs_lib/lib/cmake/CopperSpice ../diamond

Yeah! We are ready to build!

ninja install

I do need to tell you that if you just pulled down CopperSpice to a Ubuntu 20.04 LTS system, there is a shiny new dependency for the library build.

You need to install that and rebuild. Well, I rebuilt because I pulled down the updated source. It fixes or makes clearer an error message you see in the terminal.

The Drive Change

Initially this machine had a Seagate Barracuda 7200.12 160Gb drive. As I said before, my BOINC machines get the old drives put in them so I can get the last bit of use out of them. Building/changing/testing/using Diamond was too brutal for words. I deliberately left that drive in because I wanted to fix as many performance problems as I could given that Diamond uses JSON to store settings, last search, etc. Full builds were pretty bad. Just look at the specs for the drive. It’s an ATA-300 with only an 8MB buffer. Sadly, I’m old enough to remember when that drive was fast.

A quick image backup using Terabyte Drive Image for Linux and I swapped it out for a slightly better old drive from the shelf.

WDC WD2500AAKX-753CA1 (17.01H17)
SATA 300 with 16MB buffer

Still an ATA-300, but that 16MB buffer makes a real difference. I really don’t think it has anything to do with the extra 90Gig of storage. I’m only using a tiny fraction with this minimal system.
