1.  What is EL3

EL3 (Elab's Elbas Elaborator) is a tool designed to analyze HPC and GRID benchmarks. It can perform a variety of diffrent analysis generating charts and tables, using menus and checkbox to refine the data you want.

EL3 is in beta stage and can be found here: http://el3.escience-lab.org/.

2.  Uploading data

Step 1: create and upload a file for the platform you will run elbas on. This file has to follw exactly the same syntax (inclusing spaces) of the following example:

  <cpu_type>Intel Xeon X7460</cpu_type>
  <cpu_cache>9216 KB</cpu_cache>
  <cpu_cache_l3>16384 KB</cpu_cache_l3>
  <kernel>Linux #1 SMP Thu Nov 6 13:49:28 EST 2008 x86_64</kernel>
  <distribution>Mandriva Linux 2009.0</distribution>

Step 2: create and upload a file for the benchmark you will run. Some parameters are standard (i.e. Code name, dataset..) and some depends on your softwar stack (libraries, compiler...)

 <FFT_libraries>FFTW3 3.2</FFT_libraries>
 <MPI_libraries>Openmpi 1.2.3</MPI_libraries>
 <compiler>Intel Fortran Compiler 10.1.018</compiler>

Step 3: upload xml files generated by elbas. You don't need to know anything about these files but to explain how the system work here is an example:

  <output> .... plain text output .... </output>

  <output> .... plain text output .... </output>
