I tried to run HPL on a single machine, but it always fails
rtes1:/.../hpl/bin/RTES/ mpirun -np 4 xhpl
p0_30424: p4_error: Path to program is invalid while starting
/.../hpl/bin/RTES/xhpl with rsh on rtes1: -1
p4_error: latest msg from perror: No such file or directory
p0_30235: (45.056821) net_send: could not write to fd=4, errno = 32
p0_30424: (9.047947) net_send: could not write to fd=4, errno = 32
p0_30424: (60.049669) net_send: could not write to fd=4, errno = 32
if I run
rtes1:/.../hpl/bin/RTES/ mpirun -np 1 xhpl
HPL ERROR from process # 0, on line 419 of function HPL_pdinfo:
>>> Need at least 4 processes for these tests <<<
HPL ERROR from process # 0, on line 621 of function HPL_pdinfo:
>>> Illegal input in file HPL.dat. Exiting ... <<<
I am not sure what is wrong. Actually, what I need is to let Linpack provide
some measurable workload in our experiments. So I am not sure whether I need
HPL or Linpack 1000 . Who can let me know some docs about MPI and HPL? Thanks.
