Blog: 16 July 2008 - Open Sourcing Compaq's Alpha Tools for Linux
I'm in the (long and arduous) process of becoming a Gentoo/Alpha developer. This involves, firstly, becoming an Architecture Tester. This in turn, requires that I complete a quiz, mail it to the head of the Alpha team and wait. The developer who manages the alpha arch testers, of which there are none, currently, has been missing in action for 18 days.

I've benchmarked by DS20L using nbench, played with CFLAGS, and tested Compaq's Alpha-optimized math library. Results are posted for your viewing pleasure.
If you've got any suggestions for CFLAGS or other tricks to try, contact me.

A few small updates and additions to the website:
- Added a page about Alpha Assembly Programming.
- Reordered the SkyOS Build Numbers page to show newest releases at the top. There's really no need to force you to scroll to the bottom to see the latest SkyOS release.
- Added an implementation of the Leibniz Formula for Pi algorithm in Alpha Assembly

The semester is almost over and I cannot wait. There are so many things I'd rather be doing than Differential Equations. For instance:
- Writing x86-64 assembly
- Attempting to write useful patches for X, Mesa, xf86-video-ati, et al.
- Learning Alpha Assembly
- Working on my HP Alphaserver DS20L, specifications are as follows
- Dual 833 MHz EV68ALs with 4MB external L2 cache each
- 2 GB ECC Registered RAM
- Radeon X1550 256MB PCI
- 18 GB 15K RPM SCSI Drive
Unless someone corrects me, I'm going to say this is the first Alpha/R500 combination. This may also mean it is the first Linux/Alpha box to have a graphics card that supports OpenGL 2.0. It even fits in a nice 1U case.
I've also posted a nice piece of x86-64 assembly using SSE3. See my leibniz pi code page.

I've spent the last few days collecting tools, ROMs, and information on flashing PC version Radeons for usage in Macs. To save those of you interested, I've created a page with all of this information in one spot.
