Multi-processor testing

Problem statement

  • Does the amount of processing time decrease for each additional processing station added?
  • If yes, by how much?

Constants and variables

Constants:

  • Ram amount
  • Ram speed
  • Disk size
  • Cpu frequency

Variables:

  • Number of clients
  • Number of transfer(s)
  • Size of transfer(s)
  • Number of files(s)

Ideal network for testing network consists of 6nodes+ each with dual core processor, 2GB+ memory, and 6GB+ disk space. Due to limited disk capacity, current tests are running with 5 nodes.

Testing data

  • All testing data will be be preserved for analysis. Select data will be reported on this wiki.

Testing metrics

Our results are derived from running 000.zip through the archivematica pipe line, and then extracting MYSQL- timing views from the database. This gives us a clearer picture of productivity of clients.

two scripts are used to extract testing data from the database:

After you have run your test data through archivematica they are to be used: 

./automatedDistributedTestingReports.sh
./automatedDistributedTestingProcessingMachineInformationGathering.sh

you will recieve a similar fileset to this
