It appears Intel MPI is setting GOMP_CPU_AFFINITY, why? How do I prevent this? When I print my env I get: bash-4.2$ env | grep OMP OMP_PROC_BIND=true OMP_PLACES=threads OMP_NUM_THREADS=2 When I mpirun env I see that GOMP_CPU_AFFINITY has been set for me, WHY? bash-4...

数字就可以了,ppn=2 保持不变,因为我们的机器每个节点都是双cpu 的。 mpirun_rsh np 4 hostfile $PBS_NODEFILE /home/jz/helloworld 此例中-np 后的4 是并行数(2×2=4 个cpu), hostfile $PBS_NODEFILE 不需要改变。/home/jz/helloworld 是你编译好的可执行文件名, ...
