Dynare parallel not working with 4.6.1 version on mac

Installation and Setup
1

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:

[cluster]
Name = local
Members = n1

[node]
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

5

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!

6

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

7

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

The problem has been solved.

Thanks again!

@Wenddy What was the solution?

14

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.

15

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…

16

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!

17

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.

18

Is there any output that may help?

19

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.
