Scalapack p*gemr2d return codes

Hi,

I'm using the MKL Scalapack functions P*RGEM2D to distribute matrices between different contexts.  Most MKL Scalapack functions take an 'info' argument to return various error information from the function.  I cannot find any intel documentation for the meaning of the returned values in 'info' for the P*RGEM2D functions.  Any help concerning the meaning of the info values would be appreciated.

Thanks,

John
