Query: Benchmarking the computing resources at the Instituto de Astrof\'isica
  de Canarias   The aim of this study is the characterization of the computing resources used
by researchers at the "Instituto de Astrof\'isica de Canarias" (IAC). Since
there is a huge demand of computing time and we use tools such as HTCondor to
implement High Throughput Computing (HTC) across all available PCs, it is
essential for us to assess in a quantitative way, using objective parameters,
the performances of our computing nodes. In order to achieve that, we have run
a set of benchmark tests on a number of different desktop and laptop PC models
among those used in our institution. In particular, we run the "Polyhedron
Fortran Benchmarks" suite, using three different compilers: GNU Fortran
Compiler, Intel Fortran Compiler and the PGI Fortran Compiler; execution times
are then normalized to the reference values published by Polyhedron. The same
tests were run multiple times on a same PCs, and on 3 to 5 PCs of the same
model (whenever possible) to check for repeatability and consistency of the
results. We found that in general execution times, for a given PC model, are
consistent within an uncertainty of about 10%, and show a gain in CPU speed of
a factor of about 3 between the oldest PCs used at the IAC (7-8 years old) and
the newest ones.
