"Daily" Graph (5 Minute Average) Figure 14 Input and output rate (Byte/s) at se01.kallisto.hellasgrid.gr interface on July 6, 2010 In summary, the upload and download time heavily affect the performance of the application and, in most cases, they represent the main components of the overall execution time. High data transfer time and low average throughput are achieved although the network is not congested, and this is probably due to the systems (WfMS, CE, SE) load and the protocol architecture.

4.2. OPATM-BFM 4.2.1. Test Description This application deals with the users belonging to the oceanographic modeling community: they work with numerical models and with their data to get information about the past, the present or the future state of the marine environment or to study a specific process over limited space or time scales. The test consists of the following steps: 1. Registration: the user has to apply to INFN for a personal certification. 2. Login: the user opens the DORII VCR page hosted by OGS and asks for an account. 3. Credential Management: once the user has both a valid certificate and a valid VCR account, the user can upload the public and the private key to the VCR in order to create a valid proxy at each connection. 4. The workflow (from melisa.man.poznan.pl) may launch the simulation model with either (a) the most recent data or (b) historical data already stored on a SE. 5. Logout a) In this case, the workflow asks the user to select the SE and the path where input data have to be uploaded from the IE (eva.ogs.trieste.it), the CE where simulations have to be run and finally the SE and the path where output data have to be downloaded. To optimize the performance of the application it is necessary to minimize the overall execution time. Therefore, from the end-user’s perspective, the following metrics have to be measured: • Data set upload time from IE to SE • Data set download time from SE to CE • Run time at CE • Data set upload time from CE to SE b) In this case, the workflow asks the user to select the SE and the path where input data are located, the CE where simulations have to be run and finally the SE and the path where output data have to be downloaded. To optimize the performance of the application it is necessary to minimize the overall execution time. Therefore, from the end-user’s perspective, the following metrics have to be measured: • Data set download time from SE to CE • Run time at CE • Data set upload time from CE to SE DSA1.5 PUBLIC 17
