Benchmarks of QosCosGrid

QCG-Computing

The QCG-Computing service tests concerned the job submission and job management tasks, which are typical for this kind of service. The proposed two types of benchmarks used the following metrics:

• response time,
• throughput

Both types of the benchmarks were performed using specially written program on the basis of the SAGA C++ library. There were utilized two adaptors offered by SAGA C++, namely:

• gLite CREAM (based on glite-ce-cream-client-api-c) - gLite (CREAM-CE service),
• OGSA BES (based on gSOAP) - UNICORE and QosCosGrid (QCG-Computing service).

The use of the common access layer allowed to minimize the risk of obtaining incorrect results. In the same purpose, the jobs were submitted to the same resource and didn't require any data transfer.
