IV33191: WARNING MESSAGE WHEN MAX CPU

Fixes are available

APAR status

Closed as program error.

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.
