FORCE_BLOCK_SIZE {Logical} | |
Ensure for small matrices that the layout is compatible with bigger ones, i.e. no subdivision is performed (can break LAPACK!!!). | |
This keyword cannot be repeated and it expects precisely one logical. | |
The lone keyword behaves as a switch to .TRUE. | |
Default value: .FALSE. |
NCOL_BLOCKS {Integer} | |
Defines the number of columns per scalapack block in the creation of vlock cyclic dense matrices | |
This keyword cannot be repeated and it expects precisely one integer. | |
Default value: 32 |
NROW_BLOCKS {Integer} | |
Defines the number of rows per scalapack block in the creation of block cyclic dense matrices | |
This keyword cannot be repeated and it expects precisely one integer. | |
Default value: 32 |
TYPE_OF_MATRIX_MULTIPLICATION {Keyword} | |
Allows to switch between scalapack pdgemm and dbcsr_multiply. On normal systems pdgemm is recommended on system with GPU is optimized and can give better performance. NOTE: if DBCSR is employed FORCE_BLOCK_SIZE should be set. The perfomance on GPU's dependes crucially on the BLOCK_SIZES. Make sure optimized kernels are available. | |
This keyword cannot be repeated and it expects precisely one keyword. | |
Default value: PDGEMM | |
