I got it, thank you, Michael!
Since HTCondor dates back to before the days of multi-processor systems, the old static-slot configuration abstracts each core in a multi-core system as a separate machine in keeping with the original one-core==one-machine paradigm. Using partitionable slots brings the resource allocation into the modern multi-core age.

Now i can run your MPI program with correct output. Thank you so much!
I am a little bit confused by the concept "machine". In this presentation,Âhttps://meetings.internet2.edu/media/medialibrary/2015/10/19/20151008-thain-htcondor-admin-tutorial.pdf
it says: "Machine â An individual computer, managed by one startd", this means "machine" is a physical machine.
but when I run condor_q on my 24-core server(I have only this server), i got result as follows:
Â Â Â Â Â Â Â Â Â Â ÂMachines Owner Claimed Unclaimed Matched PreemptingÂ Drain
Â Â Â Â X86_64/LINUXÂ Â Â Â24Â Â Â0Â Â Â Â4Â Â Â Â 20Â Â Â Â0Â Â Â Â Â 0Â Â Â 0
Â Â Â Â Â Â Â ÂTotalÂ Â Â Â24Â Â Â0Â Â Â Â4Â Â Â Â 20Â Â Â Â0Â Â Â Â Â 0Â Â Â 0
Here "machines" is 24, it means it's not a "physical" machine, but a core or a slot.
Could you please clarify for me?Â In addition, what does node mean? My condor version is 8.6.12 for CentOS.
