Originally just a personal homepage, Frank4DD.COM grew over the years into a multi-site operation that bridges the content from purely private to professional. Below are the four separate web sites that carry dedicated topics:

Linux Cluster for High Performance Computing

How to build a diskless Linux Cluster
I have been fascinated by clusters since 1995, when DEC VMS clusters where state-of-the-art and first Windows clusters emerged for simple storage sharing. Almost a decade later, cluster technology becomes mainstream through Linux, with falling hardware prices making it affordable for "home" use. What could I use a cluster for? Finally start my education in 3D Graphics Rendering and Computer Art Design? Donate power to SETI? Compute rainbow tables and check out new ways of crunching passwords? [read article]

Sun's Sparc Classic with Solaris 9

Sun Sparc Classic
In todays fast-paced society, IT technology has gotten such a short lifespan were systems become obsolete in a year or two, creating a throw-away mentality and endless upgrade cycles at an ever increasing speed.

Keeping Time with NTP and a WWVB Radio Receiver

Setup a NTP time source
Almost everything in modern computers relates in some way to time: CPU cycles, bus frequencies, graphics refresh rates, file dates, even a simple cursor blink. Correct time is fundamental for reliable and secure computing. Yet setting and keeping correct time is one of the challenges standard computers didn't solve yet. Computer time happily drifts away and relies on the user to be set, while any cheap digital watch keeps better time when radio synchronized to a public time service. But there is help out there, NTP [read article]
