What is VE

VE stands for Vector Engine which is vector processors of SX-Aurora TSUBASA.

Notice

1. This software needs binutils for VE. It is available on the SX-Aurora TSUBASA yum repository including SDK runtime for free.
2. This software can compile only C language.
   • Only C compiler is available.
3. This software can't generate vector instructions.
4. It is required to use ncc, nc++, or nfort which are compilers for SX-Aurora TSUBASA to link objects compiled by ncc, nc++ or nfort.
5. This software is developed only for the purpose to build glibc for VE. Please note that NEC verified only the functionality required for it.
6. NEC doesn't support this software as the SX-Aurora TSUBASA product software. Please note that NEC is not obligated to respond if user sends a bug report.

Known Issues

1. A binary may malfunction when optimize options are enabled. In such case, use '-O0' option.
2. Gcc for VE is installed to /opt/nec/ve/bin/gcc. When user set /opt/nec/ve/bin in $PATH before /usr/bin, /opt/nec/ve/bin/gcc is invoked instead of /usr/bin/gcc.
   • NEC MPI setup script adds /opt/nec/ve/bin into the head of $PATH. Therefore, a build of VH side MPI program fails.
   • A command expecting /usr/bin/gcc may invoke /opt/nec/ve/bin/gcc.
