    Hello!
    
    Does upcrun support placing threads/processing on different sockets of a multi-core node? Like, on a Cray XT5 (just as an example), I can specify "aprun -S 1" to ensure that 1 MPI process is placed on each socket. I know about "upcrun -c 2" to use only 2 cores, but I guess this does not mean 1 core on each socket.
    
    Thanks in advance,
    Gabriele
