During idling periods, the 18 nodes are exercised at regular intervals by running the Linpack
benchmark (Dongarra et al.

High Performance Linpack
was run on the racks of servers while thermal data, airflow rate data, and infrared images were captured.
The IDC Balanced Rating is based on a mix of Linpack
, SPECfp_Rate, SPECint_Rate, and STREAM TRAID benchmark tests.
In the same way, we use the LAPACK and LINPACK
linear algebra routines in the LinearSolver hierarchy as well as the BLAS subroutines throughout the implementation for vector operations.
also points out the difference between mathematics as practiced by the computationalist and by the noncomputationalist.
Whetsone, Dhrystone, Linpack
, SPEC benchmark suite, mflops, and mips are all names to measure how fast a computer runs a program.
The new leader in the LINPACK
benchmark is the Department of Energy (DOE) supercomputer from Oak Ridge National Laboratory (ORNL), Summit.
as the previous leader, the Tianhe-2, which posted a LINPACK
The Galaxy S4 Active once again proves to be the winner in the Linpack
test with a score of 818 points, which is about 4% better than its competitors and way ahead of its rivals.
It is obvious that, besides LINPACK
, there are various SW packages to measure the performance of SCs i.e.
