Obviously, the HPC (High Perfomance Computing) and Scientific-Computing market is expected to continuously growing. According to IDC, the current HPC market is around $10 billion, which is 20% of the total server market. The research company has forecast the HPC market to grow to $15.6 billion by 2012.
By the way, In my opinion, currently, the non-IT company (e.g., chemistry, bio-medical, ... , etc) needs these HPC technologies, rather than web service IT company. Because, innovation of web service doesn't always require a high degree of skill or scientific computing. (Of course, there is some demands from the part of graph/network data processing in web service IT company)
For this reason, currently I consider to implement the Hama as a solution aimed at small HPC market.
