Connection error with MacOS X 10.12 and Stata 15

[sarahhaj]

Hi,

I am trying to use the -parallel- command on MacOS X 10.12 and Stata/IC 15.1 and run into some connection issues. I tried to replicate the minimal example with the -egen- command which gives me the following output:

. ssc install parallel, replace
checking parallel consistency and verifying not already installed...
all files already exist and are up to date.

. mata mata mlib index
.mlib libraries to be searched are now
    lmatabase;lmataado;lmataerm;lmatafc;lmatagsem;lmatamcmc;lmatamixlog;lmataopt;lmatapath;lmatapostest;lmatapss;lmat
> asem;lmatasp;lmatasvy;lmatatab;lparallel

. 
. parallel setclusters 2, f
N Clusters: 2
Stata dir:  /Applications/Stata/Stata.app/Contents/MacOS/Stata

. 
. sysuse auto

. 
. parallel, by(foreign): egen maxp = max(price)

cluster 0001 has finished with a connection error -601- (timeout) (see more)...
cluster 0002 has finished with a connection error -601- (timeout) (see more)...

Can someone tell me what's wrong with it?

I am rather new to Stata and to parallel processing and would greatly appreciate any suggestions.
Thanks, Sarah

Can you check that you:

• Have checked that the examples in the help work.
• Are using the newest release (see here for latest release version number).

Thank you!
I noticed that I had not the newest release (the ado file was from version 1.15.8.19).

I installed the newest version from the project website and now I get the following error message:

. parallel setclusters 4
  parallel_setclusters():  3001  expected 1 to 2 arguments but received 3
                 <istmt>:     -  function returned error

It looks like you didn't uninstall the SSC version. Can you uninstall parallel and then install the latest from GitHub.
