Condor | A very simple framework for PHP | Application Framework library

An HTML div element contains lists of endangered species grouped by continent and the species population status.

I am attemping to do the tutorial from MDN called 'XMLHttpRequest'. However, the request.open('GET', url) keeps returning back undefined when I try to use it on a txt file in the local directory. I consoled logged the url and request and they come back fine. Below is my code along with the txt file I am trying to use for this project which is in the local directory using VS code as an editor along with the live servor Port: 5500.

I have a list of cars as below:

I am trying to run a job, but condor can't seem to find my file.

I've made sure that:

1. the file is there by doing an ls and cat on its absolute path
2. run it from a condor interactive session
3. give it the right permissions so that it runs it.

I've done that but I get this error:

When using condor for distributing jobs across a dedicated computer cluster, one first submits the jobs to the cluster and then waits for them to actually start running. Depending on multiple factors, they might stay in an idle state for quite some time, even hours.

Let us say I just compiled the code that is going to be run in the jobs. I can submit the jobs via a condor submission file. I then realize I would like to change the original code, either because there is some bug in it, or else because I want to try different parameters. In the case the code finishes compiling while the jobs are still in an idle state, which version is going to be run in the cluster? In other words, does condor somehow stores a snapshot of the code when the jobs are submitted, or it just picks it when the jobs start running?

Despite thinking the first option sounds way more reasonable, I have evidence from my own work that the second is the one that actually happens.

so I have an executable file fit that I want to run with HTCondor. The executable takes an integer 0 <= i <= 9 as argument. I would like to associate i to be the job process number: $(Process). So I have a submit file such that:

This is driving me crazy, because it should be very simple and yet I can't seem to make it work. When I look at the documentation for Condor, I see that the condor_q command should return information in this format [Source]:

I am using Condor to perform a large number of processing tasks in a distributed way. There are two processing stages. In the first processing stage, I execute a tool UMPTEEN times to parse some subset of the source data and convert that to an intermediary file. Each execution of the tool is independent of all the others. So, that lends itself well to using to Condor.

The catch is that the tool may decide not to output any intermediary file. Thus, I cannot know a priori how many intermediary files I will have; the number may be less than UMPTEEN. Another catch is that I am agnostic about what the name of the intermediary file will be; I only know the filename after it has been created by the tool.

In the second processing stage, I execute other tools to convert each intermediary file to other destination files with different formats. I would like to use Condor for that also. But, to write a submit description file for that requires that I know exactly how many intermediary files I have to convert and what their filenames are.

What I attempted is to have a "generate_stage2" node in my stage1 DAG that depends on completion of the first node. In the "generate_stage2" node, I run a Python script that:

• searches for the intermediary files;
• writes submit description files that will convert those intermediary files to the destination formats;
• calls condor_submit_dag to perform that second DAG.

But, submitting the second DAG fails. I suspect that Condor does not like it when I call condor_submit_dag within a node that is currently running in the first DAG.

Is what I am attempting possible? Is there a way for one DAG to trigger another DAG?

Following are examples of my submit description files, which hopefully explain what I have attempted.

I am trying to replace string values in a column without creating a copy. I have looked at the docs provided in the warning and also this question. I have also tried using .replace() with the same results. What am I not understanding? Code:
