java.lang.Object
  java.lang.Thread
      com.multicorebsp.core.BSP_PROGRAM
          com.multicorebsp.bspedupack.BSPmv_driver

All Implemented Interfaces:

java.lang.Runnable

Direct Known Subclasses:

BSPmv_fully_buffered, BSPmv_half_buffered, BSPmv_interleaved

public abstract class BSPmv_driver
extends com.multicorebsp.core.BSP_PROGRAM

Distributed-/shared-memory sparse matrix--vector driver application. Does all I/O and initialisation for either one of the available SpMV kernel codes; see below.

See Also:

BSPmv_fully_buffered, BSPmv_half_buffered,
By default, BSPmv_half_buffered is used. See the static main function for switching to other variants.
