Rescale releases live tailing

The starting paragraph is just confusing. Its full of acronyms and long sentences. The reader feels lost. Not a good way to start a blog post (or a news release).
Here it is:
The solvers in modern simulation codes in applications such as CFD, FEA and molecular dynamics are becoming more sophisticated by the day. While taking advantage of (i) new technologies in hardware and (ii) advances in numerical methods, many of these solvers require close monitoring to ensure they converge to a useful and correct solution. It is important to know when a simulation reaches an un-desired state so it can be stopped and the problem can be diagnosed.
How would I re-write that? Ok, let's find out what the underlying subject is.
* It is important to know when a simulation reaches an un-desired state so it can be stopped and the problem can be diagnosed.*
This is the main subject for the main paragraph. It should be the opening thought, and not the last sentence in it. But, at its current state, is not very clear. Let's re-write it:
Rescale releases a new feature. It is called "live tailing." The feature allows you to track simulations. You will be able to know when a simulation has reached an undesired state. This way, troubleshooting problems becomes easier.
See? It introduces the reader to what the feature is, covers the main points, and allows for a good reading flow.
But let's continue.
We call this feature ‘live tailing’.
Live tailing allows Rescale customers to monitor any output file for jobs running on the cluster with just one click. This feature replaces the currently painful process of dealing with ssh keys, logging into the cluster, and / or deciphering where the relevant files are located on the server. Rescale’s live tailing is intuitive, user-friendly, highly secure, and much more efficient than traditional monitoring.
The term live tailing is a good one. But they forgot to denote the sub-headline as such. A simple <h4></h4> would have fixed it. The paragraph is a disaster. Worse than the first one. That second sentence. My god! Its difficult to read. Let's try and re-write this in a manner that is easy to read, and drives the point home.
We call this feature Live Tailing.
Here is what Live Tailing does for you: it monitors the output file of any job you may be running in a cluster. It replaces the painful process of:
- dealing with ssh keys
- logging into the cluster itself
- deciphering where all of the relevant files are located
In simple words, it is an intuitive and user friendly way to monitor your jobs. It is also highly secure, and more efficient that traditional monitoring.
Now, this is another confusing part. The "how it works" part is out of place. I would have simply put in a link to a free trial or a video demonstration. I'm skipping this part.
Oh yes, the "Why is it useful" part. This is a good sub-headline to use. Let's read:
As engineers, we recognize how important it is to track the status of any analysis at any time. Here are some examples of useful applications for live tailing:
- Monitor progress of a simulation, either to extrapolate total expected runtime or to ensure that the simulation doesn’t enter a negative state.
- View output plots to quickly analyze important trends and metrics of the simulation.
- Monitor load balancing for parallelized simulations to diagnose inefficient behavior and to help the customer choose the correct number of processors.
- Monitor time step conditions such as CFL or adaptive grid conditions to ensure that the simulation doesn’t “blow up.” Simulations that creep along and blow up in time or size can now be stopped quickly.
This is good. Very good. To the next part:
Does live tailing work with image files as well?
Yes. Some simulation codes are able to generate image files such as meshes, graphs or surface plots. These files can be live tailed as well. Clicking on a file that is a jpg, png or gif will display the image right inside the browser. Check out this aircraft landing gear example using Gerris (http://gfs.sourceforge.net/wiki), an open-source CFD code, with data provided by the AIAA.
This is also very good. Lots of good technical bits there. The link to the source file is particularly smart. Well done.
There is something missing after that paragraph. The article lacks a summary and a close. I'm torn. The first half of the article reads very poorly, but the second half reads very well. As if this was written by two (or more) people. Or maybe this is just a draft published too soon? I'm going to take what I wrote, and combine it with what they wrote. Let's see how it reads.
