The userspace tracer is designed to provide detailed information about userspace activity. Like the kernel tracer, performance is the main goal. Tracing does not require system calls or traps. UST instrumentation points may be added in any userspace code including signal handlers and libraries.

This is a compressed format for representing multidimensional floating-point and integer arrays. zfp provides compressed-array classes that support high throughput read and write random access to individual array elements. zfp also supports serial and parallel (OpenMP and CUDA) compression of whole arrays, e.g., for applications that read and write large data sets to and from disk.

Zthreads is an advanced platform-independent, object-oriented threading and synchronization library. Designed and tested under POSIX & Win32 systems.

The vertical blanking interval (VBI) is an interval in a television signal that temporarily suspends transmission of the signal for the electron gun to move back up to the first line of the television screen to trace the next screen field.

Ukwm is a small window manager, using GTK+ and Clutter to do everything.
