IBM Spectrum LSF
IBM Spectrum LSF (LSF, originally Platform Load Sharing Facility) is a workload management platform, job scheduler, for distributed high performance computing (HPC) by IBM. Details It can be used to execute batch jobs on networked Unix and Windows systems on many different architectures. LSF was based on the ''Utopia'' research project at the University of Toronto. In 2007, Platform released ''Platform Lava'', which is a simplified version of LSF based on an old version of LSF release, licensed under GNU General Public License v2. The project was discontinued in 2011, succeeded by OpenLava. In January, 2012, Platform Computing was acquired by IBM. The product is now called IBM Spectrum LSF. IBM Spectrum LSF Community Edition is a no-charge community edition of the IBM Spectrum LSF workload management platform.

Laser-stimulated Fluorescence
Laser-induced fluorescence (LIF) or laser-stimulated fluorescence (LSF) is a spectroscopic method in which an atom or molecule is excited to a higher energy level by the absorption of laser light followed by spontaneous emission of light. It was first reported by Zare and coworkers in 1968. LIF is used for studying structure of molecules, detection of selective species and flow visualization and measurements. The wavelength is often selected to be the one at which the species has its largest cross section. The excited species will after some time, usually in the order of few nanoseconds to microseconds, spontaneously decay and emit a photon at a wavelength longer than the excitation wavelength. This fluorescent light is typically recorded with a photomultiplier tube (PMT), charged-coupled device (CCD), or filtered photodiodes. Types Two different kinds of spectra exist, disperse spectra and excitation spectra. The disperse spectra are performed with a fixed lasing wavelength, as ...
