Are there functions to calculate the local indexes of block-cyclic distribution?

I want to transfer a global index m to local indexes (p,b,i) and vice versa.

Are there functions to do the calculations, m -> (p,b,i) and (p,b,i) -> m, in scalapack?

Hi Ye,

You could use auxiliary function p?lacp3 in ScaLAPACK. This function could copy global parallel array into local arrays. Learn more information please visit https://software.intel.com/en-us/node/521586
