# DIANA - Fault Tolerance

A study on the fault tolerance of **DI**visive **ANA**lysis, a top-down clustering algorithm.

### Basic Setup

  #### Compile

    $ mkdir build

    $ cd build

    $ cmake ..

    $ make

  #### Generate Input

    $ ./datagen <#instances>  <#attributes>

  #### Generate Gold output

    $ ./simple_diana -i  -o  -t  -l 

## DWC (Duplication With Comparison)

Spacial duplication of the DIANA kernel. Two parallel executions are ran and then the results are compared, 

possibly detecting an SDC. If so, a counter is updated in a file.

    $ ./dwc_diana -i <.txt input> -o <.bin output> -d <.txt name to count detected sdcs> [optional: -a <.txt output1> -b <.txt output2>]

## Selective Hardening

Duplication and comparison of critical variables and the operations that update them.

## Radiation Tests

Before running the benchmark, the script https://github.com/UFRGS-CAROL/radiation-benchmarks/blob/master/scripts/install.py should be executed. This script will create the folder to store the log files and create the conf file in /etc/radiation-benchmark.conf

      $ ./radiation_diana <-i input file> <-o output file> <-g golden file> <-t kmeans threshold>

    

* Configuration used for Core i7-7700HQ (simple_diana takes 3.5 seconds with this processor)

  - input and gold generated

    $ ./datagen 7000 -f 20

    $ ./simple_diana -i 7000_20f.txt -o diana_gold.bin -t 0.001

  - configurations executed

    $ ./radiation_diana -i 7000_20f.txt -o diana_out.bin -g diana_gold.bin -t 0.001 -l 1000000
