DOC: Supported Virtual Applications

• The list of supported Virtual Applications can be obtained with the command typelist on the CLI.
• The details of a particular Virtual Application are displayed with the command typeshow (vapp type) on the CLI.

  • Example: (TESTCLOUD) typeshow cassandra_ycsb

         The AI with the type cassandra_ycsb has the following configuration on experiment (Cloud TESTSIMCLOUD) :
        description:  Deploys a Cassandra cluster (N seed nodes and M data nodes), plus one VM
    

running the YCSB benchmark. This single VM sends requests to all seed node VMs simultaneously.

• LOAD_PROFILE possible values: "workload"{a-f} (for a proper description, consult the section "Core Workloads" on the YCSB documentation)
• LOAD_LEVEL meaning: number of threads on YCSB (parameter -threads).
• LOAD_DURATION meaning: not used, a run ends when all YCSB operations (default is 1000) are finished.
• COMMENT: One of the "Big Data" Workloads. One of the two Virtual Applications types selected for the SPECCloud 2014 v1.0 benchmark. When new seed nodes are added (after an "airesize") the VM running YCSB will automatically direct requests to these new seed nodes.
