Hi,

I have to gather distributed matrixcalculatedwithpzgemm function at root processor.ScaLAPACK_UNMAP functionfrom "Math Libraries for Windows HPC" does what I want. is there any function in MKL does same thing. NO reply is also help me. if there isn't, I try to write using mpi_send,etc.. function.it is very complicated algorithm to collect true data to correct place.

Thanks

Hi,

Please take a look at the p?lacp3 ScaLAPACK routine. It is intended for gathering square matrices. Is it suitable for you?

Thanks,

Artem

Hi Artem,

my matrix is complex ,there isn't pzlacp3 function in mkl. Also,my submatrixare not square. In this stituation, I think this functionisn't suitable for me. If I'm wrong please correct me.

Thanks,
