I'm testing this with 1.8.3 after fixed the my incorrect printf, and still get different results (and the nbcoll one is wrong) using one process (for two or more everything's OK). $ mpicc -DNBCOLL=0 ireduce_scatter.c && mpiexec -n 1 ./a.out [0] rbuf[0]= 1 expected: 1 $ mpicc -DNBCOLL=1 ireduce_scatter.c && mpiexec -n 1 ./a.out [0] rbuf[0]=60 expected: 1 -- Lisandro Dalcin ============ Research Scientist Computer, Electrical and Mathematical Sciences & Engineering (CEMSE) Numerical Porous Media Center (NumPor) King Abdullah University of Science and Technology (KAUST) http://numpor.kaust.edu.sa/ 4700 King Abdullah University of Science and Technology al-Khawarizmi Bldg (Bldg 1), Office # 4332 Thuwal 23955-6900, Kingdom of Saudi Arabia http://www.kaust.edu.sa Office Phone: +966 12 808-0459
