ACCEL Flag Description
SGI SGI C3108-TY11

Base Optimization Flags

C benchmarks

• • -O2
  • 
  • OPTIMIZE

  • -O2 Optimize even more. GCC performs nearly all supported optimizations that do not involve a space-speed tradeoff. The compiler does not perform loop unrolling or function inlining when you specify -O2. As compared to -O, this option increases both compilation time and the performance of the generated code.

• • -I/opt/intel-ocl/2013-3.2.1-16712/intel/opencl-1.2-3.2.1.16712/include
  • 
  • gcc_l, gpp_l, gfortran_l
  • EXTRA_CFLAGS

  • Include path to Intel OpenCL library header

• • -lOpenCL
  • 
  • gcc_l, gpp_l, gfortran_l
  • EXTRA_LIBS

  • Link with the OpenCL library
