 Test which checks if WORKSHARE is present. 2.0 omp workshare omp critical !******************************************************************** ! Function: omp_workshare ! ! by Chunhua Liao, University of Houston ! Oct. 2005 - First version ! ! The idea for the test is that if WORKSHARE is not present, ! the array assignment in PARALLEL region will be executed by each ! thread and then wrongfully repeated several times. ! ! TODO:Do we need test for WHERE and FORALL? ! A simple test for WHERE and FORALL is added by Zhenying Liu !******************************************************************** INTEGER FUNCTION omp_workshare() IMPLICIT NONE INTEGER result,i INTEGER scalar02,scalar12,scalar22,scalar32,count REAL, DIMENSION(1000)::FF INTEGER scalar0,scalar1,scalar2,scalar3 INTEGER, DIMENSION(1000)::AA,BB,CC REAL, DIMENSION(1000)::DD COMMON /orphvars/ scalar0,scalar1,scalar2,scalar3, & AA,BB,CC,DD result=0 scalar0=0 scalar02=0 scalar1=0 scalar12=0 scalar2=0 scalar22=0 scalar3=0 scalar32=0 count = 0 AA=0 BB=0 do i=1,1000 CC(i) = i FF(i) = 1.0/i end do !\$OMP PARALLEL !\$OMP WORKSHARE ! test if work is divided or not for array assignment AA=AA+1 ! test if scalar assignment is treated as a single unit of work scalar0=scalar0+1 ! test if atomic is treated as a single unit of work !\$OMP ATOMIC scalar1=scalar1+1 ! test if critical is treated as a single unit of work !\$OMP CRITICAL scalar2=scalar2+1 !\$OMP END CRITICAL ! test if PARALLEL is treated as a single unit of work !\$OMP PARALLEL scalar3=scalar3+1 !\$OMP END PARALLEL WHERE ( CC .ne. 0 ) DD = 1.0/CC FORALL (I=1:1000) CC(i) = -i !\$OMP END WORKSHARE !\$OMP END PARALLEL !sequential equivalent statements for comparison BB=BB+1 scalar02=scalar02+1 scalar12=scalar12+1 scalar22=scalar22+1 scalar32=scalar32+1 ! write (1,*) "ck:sum of AA is",SUM(AA)," sum of BB is ",sum(BB) if (SUM(AA)/=SUM(BB)) then write(1,*) "Array assignment has some problem" result=result +1 endif if (scalar0/=scalar02) then write(1,*) "Scalar assignment has some problem" result = result +1 endif if (scalar1/=scalar12) then write(1,*) "Atomic inside WORKSHARE has some problem" result = result +1 endif if (scalar2/=scalar22) then write(1,*) "CRITICAL inside WORKSHARE has some problem" result = result +1 endif if (scalar3/=scalar32) then write(1,*) "PARALLEL inside WORKSHARE has some problem" result = result +1 endif do i=1,1000 if ( abs( DD(i)- FF(i)) .gt. 1.0E-4 ) then count = count + 1 end if end do if ( count .ne. 0 ) then result = result + 1 write(1,*) "WHERE has some problem" end if count = 0 do i=1,1000 if ( CC(i) .ne. -i ) then count = count + 1 end if end do if ( count .ne. 0 ) then result = result + 1 write(1,*) "FORALL has some problem" end if !if anything is wrong, set return value to 0 if (result==0) then = 1 else = 0 end if end
