Dynare parallel not working with 4.6.1 version on mac

Dear Houtan,
I’m using MATALAB_2018a on macOS Catalina. Under Dynare 4.5.7 I can run parallel. However, it doesn’t work under 4.6.1 version. Here is my dynare_parallel.txt configuration:

Name = local
Members = n1

Name = n1
ComputerName = localhost
CPUnbr = 12
DynarePath = /Applications/Dynare/4.6.1/matlab
MatlabOctavePath = /Applications/MATLAB_R2018a.app/bin/matlab

Did you have a look at https://mutschler.eu/dynare/parallel/macos/ ?
Also, you need to @HoutanBastani

Yes, Completely familiar with it and as I said, I was using it under 4.5.7 and even 4.6.0 but not working on 4.6.1! I should say I didn’t install GCC to use ‘use_dll’ but I think it doesn’t have any issue with that!

Then this sounds like a bug that needs to be investigated

I just used a trick! I installed 4.6.1 on my mac pro and 4.6.0 on my macbook pro then copied matlab folder from dynare 4.6.0 and pasted it on 4.6.1. With this I could use parallel with the above configuration (estimated a ramsey policy model). However, there are some problems with it due to different versions!

What is the actual error you get? Also can you run dynare yourmodfile parallel_test?

You can also sent me the mod file, I can try to run it on my mac virtual machine.

There is no error, dynare runs the model, gives mode_check plots but when it should start parallel, it does nothing! when running parallel_test, there is also no error. Everything’s fine in earlier versions but not working on 4.6.1! I can run my model by installing earlier versions and even I estimated a ramsey policy model on 4.6.0 using parallel but not on 4.6.1!

Unfortunately, I am unable to reproduce your error. Using your config file in ~/.dynare (decreasing CPUnbr because I don’t have that many and changing to R2019b) and running dynare ls2003.mod parallel with Dynare 4.6.1, I am unable to reproduce your error. That said, I am running 10.14.6.

Hi, mutschl,
I had used parallel option. Using parallel_test, it is ok.

Testing computer -> localhost <- ...

Check on Local Variable ..... Ok!

Checking Hardware please wait ...
Hardware has 4 Cpu/Cores!
User requires 4 Cpu/Cores!
Check on CPUnbr Variable ..... Ok!

Test for Cluster computation, computer localhost ..... Passed!

AnalyseComputationalEnvironment returned with Error Code: 0

but when I use dynare mymodel parallel, something is wrong

Win 10
dynare 4.6.1

The problem has been solved.

Thanks again!

@Wenddy What was the solution?

Sorry, I wasn’t able to work last week, but I am glad that you figured it out. Please let other users know what the issue was, so we can tag this as solved.

I had a similar issue on our university cluster running centOS. For some reason I needed to include my own public ssh key (which is usually in .ssh/id_rsa.pub to the authorized keys in .ssh/authorized_keys.) No clue why…

In case which parallel not working, I had installed PSTools into C:\App\dynare\4.6.1\PSTools

My solution:move PSTools file to another path,e.g. C:\App\PSTools

Then it’s ok!

I suffered the same issue and could not solve the problem by changing the path of pstool. I tried matlab 2019b and 2020a, b, win10, dynare 4.6.1. But when I used the parallel about 8 months ago, it could run without any issue. I was not sure why this issue happened.

Is there any output that may help?

My problems is similar to Wenddy’s. It shows “ec 不是内部或外部命令” and only one MC runs. I find the issue is caused by the chinese-character name of the folder in which my model.mod file is. When I change it into a name in english. The issue is solved.
