I have put up a new version of the Dimensioning Toolkit.
Now, there is a particular version for MySQL Cluster 6.2 and MySQL Cluster 6.3.
The reason for this split is that the libraries and include files are in different locations (include/ and lib/ in 6.2, but lib/mysql and include/mysql in 6.3).
I don't know why the build team changes this between versions (even builds) and so often... very annoying.
Anyways, follow the links to download:
Dimensioning Toolkit for MySQL Cluster 6.2
Dimensioning Toolkit for MySQL Cluster 6.3
