EPSPRIMMESetBlockSize
The maximum block size the code will try to use. The user should set this based on the architecture specifics of the target computer, as well as any a priori knowledge of multiplicities. The code does NOT require BlockSize > 1 to find multiple eigenvalues. For some methods, keeping BlockSize = 1 yields the best overall performance.
