SLURM and Python multiprocessing pool on a cluster

Asked 2021-Jun-15 at 13:42

I am trying to run a simple parallel program on a SLURM cluster (4x raspberry Pi 3) but I have no success. I have been reading about it, but I just cannot get it to work. The problem is as follows:

I have a Python program named remove_duplicates_in_scraped_data.py. This program is executed on a single node (node=1xraspberry pi) and inside the program there is a multiprocessing loop section that looks something like:

ANSWER

Answered 2021-Jun-15 at 06:17

Pythons multiprocessing package is limited to shared memory parallelization. It spawns new processes that all have access to the main memory of a single machine.

You cannot simply scale out such a software onto multiple nodes. As the different machines do not have a shared memory that they can access.

To run your program on multiple nodes at once, you should have a look into MPI (Message Passing Interface). There is also a python package for that.

Depending on your task, it may also be suitable to run the program 4 times (so one job per node) and have it work on a subset of the data. It is often the simpler approach, but not always possible.

ANSWER

Answered 2021-Jun-11 at 14:41

In Slurm the number of tasks is essentially the number of parallel programs you can start in your allocation. By default, each task can access one CPU (which can be core or thread, depending on config), which can be modified with --cpus-per-task=#.

This in itself does not tell you anything about the number of nodes you will get. If you just specify --ntasks (or just -n), your job will be spread over many nodes, depending on whats available. You can limit this with --nodes #min-#max/--nodes #exact. Another way to specify the number of tasks is --ntasks-per-node, which does exactly what is says and is best used in conjunction with --nodes. (not with --ntasks, otherwise it's the max number of tasks per node!)

So, if you want three nodes with 72 tasks (each with the one default CPU), try:

Your issue looks similar to another issue, see here: Certificate for doesn't match any of the subject alternative names

So I would assume that if you add the SAN extension localhost as DNS and the ip address of localhost to the elasticsearch certificate it should work. So adding the following additional parameters: --dns localhost --ip 127.0. 0.1. Can you give the command below a try and share your results here?

QUESTION

Kubernetes share temporary storage to upload file async

Asked 2021-May-22 at 01:48

Following this post and this, here's my situation:
Users upload images to my backend, setup like so: LB -> Nginx Ingress Controller -> Django (Uwsgi). The image eventually will be uploaded to Object Storage. Therefore, Django will temporarily write the image to the disk, then delegate the upload task to a async service (DjangoQ), since the upload to Object Storage can be time consuming. Here's the catch: since my Django replicas and DjangoQ replicas are all separate pods, the file is not available in the DjangoQ pod. Like usual, the task queue is managed by a redis broker and any random DjangoQ pod may consume that task.
I need a way to share the disk file created by Django with DjangoQ.

The above mentioned posts basically mention two solutions:
-solution 1: NFS to mount the disk on all pods. It kind of seems like an overkill since the shared volume only stores the file for a few seconds until upload to Object Storage is completed.
-solution 2: the Django service should make the file available via an API, which DjangoQ would use to access the file from another pod. This seems nice but I have no idea how to proceed... should I create a second Django/uwsgi app as a side container which would listen to another port and send an HTTPResponse with the file? Can the file be streamed?

...

ANSWER

Answered 2021-May-22 at 01:48

Third option: don't move the file data through your app at all. Have the user upload it directly to object storage. This usually means making an API which returns a pre-signed upload URL that's valid for a few minutes, user uploads the file, then makes another call to let you know the upload is finished. Then your async task can download it and do whatever.

Otherwise you have the two options correctly. For option 2, and internal Minio server is pretty common since again, Django is very slow for serving large file blobs.

QUESTION

Do I have to zip up the artifacts before deploying to Azure App Service?

Asked 2021-May-14 at 11:58

I am currently finishing up creating a CI dev pipeline and referencing the following documentations

The references all show that the artifacts get zipped up first, published, then deployed.

However, the project developer told me that after the .NET build, he just copies/deploys the generated AngularOutput artifacts to the Azure app service.

I tested it that way with archive task then publish, and the CI pipeline worked just fine. However, I also tested out publishing directly without prior archiving, and i changed the path to \Bundles\AngularOutput, and the publish step succeeded just fine and displayed the published artifacts

So the question is, if publish works without zipping/archiving first, then can I directly deploy after the artifacts are published? and if so, what needs to be specified for the Azure App Service Deploy task: Package/Folder?

If archiving task is necessary/recommended, thats fine, but does that means Azure App Service deploy will automatically extract the zipped up artifact?

...

ANSWER

Answered 2021-May-14 at 11:58

First of all, yes you can publish your artifact without actually publishing them on the pipeline as artifact. However, if you publish them on the pipeline and have build and release pipelines separate you can redeploy without rebuilding your app.

Also you can always download artifact and publish it manually if where is a need for that. (some development/debug purposes for instance).

And Zip deploy method

which is used here

Creates a .zip deployment package of the chosen Package or folder and deploys the file contents to the wwwroot folder of the App Service name function app in Azure. This option overwrites all existing contents in the wwwroot folder. For more information, see Zip deployment for Azure Functions.

so if you need to deploy it from the build pipeline you can just put path to your zip file or to folder file where the content is.

And please consider multi stage pipeline where you can separate build and deploy phases among stages. However, in this case you need to publish your artifact as a pipeline artifact. And this pipeline artifact will be downloaded automatically on deployment job.

Apache Oozie throws ClassNotFoundException (org.apache.hadoop.conf.Configuration) during startup

Asked 2021-May-09 at 23:25

I built the Apache Oozie 5.2.1 from the source code in my MacOS and currently having trouble running it. The ClassNotFoundException indicates a missing class org.apache.hadoop.conf.Configuration but it is available in both libext/ and the Hadoop file system.

I followed the 1st approach given here to copy Hadoop libraries to Oozie binary distro. https://oozie.apache.org/docs/5.2.1/DG_QuickStart.html

I downloaded Hadoop 2.6.0 distro and copied all the jars to libext before running Oozie in addition to other configs, etc as specified in the following blog.

https://www.trytechstuff.com/how-to-setup-apache-hadoop-2-6-0-version-single-node-on-ubuntu-mac/

This is how I installed Hadoop in MacOS. Hadoop 2.6.0 is working fine. http://zhongyaonan.com/hadoop-tutorial/setting-up-hadoop-2-6-on-mac-osx-yosemite.html

This looks pretty basic issue but could not find why the jar/class in libext is not loaded.

JAVA: 1.8.0_191
Hadoop: 2.6.0 (running in the Mac)

I was able to sort the above issue and few other ClassNotFoundException by copying the following jar files from extlib to lib. Both folder are in oozie_install/oozie-5.2.1.

libext/hadoop-common-2.6.0.jar
libext/commons-configuration-1.6.jar
libext/hadoop-mapreduce-client-core-2.6.0.jar
libext/hadoop-hdfs-2.6.0.jar

While I am not sure how many more jars need to be moved from libext to lib while I try to run an example workflow/job in oozie. This fix brought up Oozie web site at http://localhost:11000/oozie/

I am also not sure why Oozie doesn't load the libraries in the libext/ folder.
