When we think of science we don’t immediately think of quality assurance and yet… scientists have to run their codes somewhere, they need hardware, the hardware needs software, and the software needs to be operated reliably and efficiently – enter the Quality Assurance (QA) team of TeraGrid: the most powerful open science resource.
Shava Smallen, the co-lead of the TeraGrid QA team, told me recently of their first venture into infrastructure clouds. The TeraGrid Science Gateway projects have been experiencing scalability problems with grid infrastructure. A potential solution came out in the form of GRAM 5; the scientists developed scalability tests to see if it solved their problem — but where could they run them? They tried Ranger, a top-of-the-line TeraGrid resource at Texas Advanced Computing Center (TACC). But Ranger is a powerful resource, very much in demand for large scientific computations that cannot run elsewhere — and thus the QA team found itself with tests all ready to run – but no resources to run them on.
