ii) The authors supposed a good scalability of the new algorithm, but the experiment's proof seems not enough, as it just gave the weak scalability comparison, which just could lead to a conclusion of improved execution time, while a strong scalability curve might be more persuasive.
`----
+As said previously, the machine we have used is reformed and currently we have no access to make other large scale tests. In fact, we consider that GMRES is quite scalable because it is used by many other researchers and tools. So we have compared our method with it using weak scalability.

iii) In the last line on the page 7, there is apparent error "multi-saplitting".
