Definitely OK to ask on SO. We need more SO question. :)

Dear Brad,
I had completely the same question when trying multi-locale runs
on a single node (Mac) much ago, so glad to find the answer :)
# Indeed, my old note says: "Is it necessary to write
'export GASNET_SSH_SERVERS="localhost localohost ...'
explicitly after enabling password-less SSH?" etc.
So, I am wondering if it is OK to ask this question on StackOverflow
(unless it is already asked/answered before)?
Best regards,

Hi Richard —
Best practice when running GASNet locally is to set:
export GASNET_SPAWNFN=L # L = local
and then there's no need to have a GASNET_SSH_SERVERS list. Give a shout
if this doesn't work for you.

Folks,
I’m trying to run multilocale on my Mac OSX 10.14.6 4 core laptop, but I
don’t believe I have the settings correct.
Build:
cd chapel-1.22.0
export CHPL_COMM=gasnet
./configure
Make
Compiling my code results in my executable plus executable_real.
To run, from
https://urldefense.proofpoint.com/v2/url?u=https-3A__chapel-2Dlang.org_docs_usingchapel_multilocale.html&d=DwIGaQ&c=C5b8zRQO1miGmBeVZ2LFWg&r=QUQW-BniEL_d2a7btR4rP5TPiNmpm1pG-Qa_xXzGVKc&m=f-uoASqUgCkyT7DF7LiW2iExfixPEwnpJl0lAx0c74Y&s=qX-sqGKh84GkiXReC9HsAQ
AN1hmUrEpyKyy_Srn7Pc0&e= :
export GASNET_SPAWNFN=S
export GASNET_SSH_SERVERS="host1 host2 host3 ..."
But since only one host, is this necessary? When I list my machine name,
I'm prompted for a passwd. If I don't list machines, I see this:
*** GASNET ERROR: Environment variable SSH_SERVERS is missing.
And if the command line is "./my_executable_real -nl {num}, I see this
error:
GASNet: Usage ' my_executable_real <num_nodes> {program arguments}'
So apparently gasnet launching syntax required here, correct?
Any help appreciate, with apologies in advance for missing some obvious
documentation.
Richard
