Error description
Run of the OMP program will output the following warning messages, when "startproc=<max cpu_id>" is specified as a XLSMPOPTS environment variable: 1587-121 SMP runtime library error. Could not bind thread to processor 1. 1587-106 The value 1 specified for option 'STARTPROC' is not in the valid range 0 to 1. All SMP run-time options have been set to their default values. The following sample program demonstrates the problem: $ cat t01.f program main parameter(n=4096) real*8 a(n),b(n),c(n) C$OMP PARALLEL DO C$OMP& SCHEDULE(STATIC) C$OMP& PRIVATE(I) do i=1,n a(i) =0.0d0 b(i) =1.0d0 c(i) =3.0d0 end do C$OMP END PARALLEL DO call sub(a,b,c,n) stop end subroutine sub(a,b,c,n) integer n real*8 a(n),b(n),c(n) return end Compile as: xlf_r -O2 -qsmp=omp -o t01 t01.f Run the t01 binary, where he maximum of cpu_id is specified as "startproc": $ export XLSMPOPTS="startproc=1" $ export OMP_NUM_THREADS=1 $ ./t01 1587-121 SMP runtime library error. Could not bind thread to processor 1. 1587-106 The value 1 specified for option 'STARTPROC' is not in the valid range 0 to 1. All SMP run-time options have been set to their default values.
