cuSOLVERMp Initialization

Overview

cuSOLVERMp requires the user to initialize the NCCL communicator before passing it to cuSOLVERMp functions. The steps are covered in the NCCL documentation and briefly described in the NCCL Initialization section of this documentation.

cuSOLVERMp versions prior to v0.7.0 used CAL. For users who are migrating from CAL to NCCL, the Migrating from CAL to NCCL section of this documentation provides the steps to migrate.

For the users of older cuSOLVERMp versions, CAL documentation remains available for reference in the CAL Initialization (Legacy) section.
