Tiger is a Beowulf type cluster dedicated to scientific computing at the
Astronomical Institute of the Charles
University in Prague. It is designed for parallel running of single-thread
computational tasks providing on-demand allocation of CPU time. The cluster
is accessible via the headnode tiger.troja.mff.cuni.cz; further
distribution of jobs to another diskless nodes is maintained by software
Wimpy developed at the Institute. The cluster
is based on the AMD x86_64 architecture and is powered by GNU Linux
(CentOS 5.4 distribution).
Main aim of this website is to provide basic user's manual - all users are
kindly asked to read at least sections Quick start
and Basic rules and to respect the rules described there.
Comments and suggestions on improvements are welcome at
wimpy@sirrah.troja.mff.cuni.cz.
