The libsysve package contains three libraries which are used by VE programs to invoke VE-specific system calls or enable an additional feature.

• libsysve: VH call, VH-VE SHM, Misc. API
  Please refer to Getting Started with VH Call with VE DMA and VH-VE SHM for more details.
  
• libveio: VE DMA, VE AIO
  Please refer to Getting Started with VH Call with VE DMA and VH-VE SHM and Getteing Started VE AIO for more details.
  
• libveaccio: Accelerated I/O
  Please refer to section 4.2 "Accelerated I/O" in SX-Aurora TSUBASA Program Execution Quick Guide for more details.

To build VE programs using libraries in the libsysve package, libsysve-devel package needs to be installed.
