Can I use SCALAPACK library on the single machine (Xeon)?

[Dan_Ghiocel]

Hi, All Experts,

      I'm wondering if I can use ScaLapack library on a single machine, since Scalapack is for distributed arch. If it is possible, would you please tell me how to set up the running environment?

     Thanks a lot.

Hi Dan, 

Yes, you can run scalapack on one singe machine as scalapack is based on MPI, which allow run on single machines or multiple machine. 

If you have installed Intel parallel Studio Cluster edition and MPI (intel MPI or other open source MPI), 

Here is one c scalapack sample and step by step environment setting for your reference

and you can refer to MKL userguide for further information.
