We have now made it easy to not only see a summary of your current usage, but have also added the ability for you to export your detailed usage. Here’s how:

  1. While logged in to your Rescale account, click on your email address in the upper right corner, and then select Account from the menu that appears.Screen Shot 2015-04-27 at 6.25.15 PM
  2. On the account page you’ll see a summary for the last few months. There is a link on the right to download your usage for each month in a comma-separated values (CSV) file, which can be easily opened by Microsoft Excel for further analysis.


You can also view a summary of any credits you have received and a usage chart by clicking on the corresponding links in the menu on the left.

It can be useful to take periodic snapshots of the working directory for a run of your Rescale job, either for restart purposes or for additional review on your local machine. Rescale makes it easy. Starting from the Status tab available on the right side of your screen (Screen Shot 2014-11-04 at 9.02.26 AM), select the run you would like to snapshot. In this case, I’m running a single run job, so there is only one option, Run #1.


Next, click the “Snapshot” button and then select the “Snapshot Run” button in the confirmation popup.

Rescale will take a snapshot of the current working directory, including subdirectories. and package up the files into a single zip file. Once that zip file is ready, a download button will appear in the modal.


You may also download this snapshot from the Results tab (Screen Shot 2014-11-04 at 9.21.07 AM). If you have made multiple snapshots over the course of the run, each one will be listed and labeled with the date and time it was taken.

Rescale makes it easy to run a design of experiments, as previously discussed in this post. Here we will provide some quick tips on template generation so your variables are formatted to your liking.

We support two methods for specifying a range of variables:
1. Uploading a comma-separated values (CSV) file, where each row is a case–also known as a “run” in Rescale parlance
2. Specifying the variable ranges directly in your browser

Once your variables are defined, you can then create templates, where the basic placeholder for a variable, such as “x”, looks like this:

If you use this syntax and specify your variables in a CSV file, then we will replace the placeholder with the value from your CSV without any modification. This can be useful if you would like to include non-numeric data in a file specific to that case. For example, you might include a description of each case as a comment in an input file, which may be more meaningful than the identifier we automatically assign to that case. So if your CSV looks like this:

And your input file template looks like this:

Then the processed template for the first case would look like this:

You may prefer to have a specific consistent number format in the file, regardless of how the variable was specified in the CSV or how you specified it in the browser. For this situation, you can supply an additional format instruction, using a “0” or “#” for a digit, where trailing zeros are absent if the “#” symbol is used. Here are some examples:

x ${x?string(“0”)} ${x?string(“0.0”)} ${x?string(“0.00##”)}
0.9 1 0.9 0.90
1.49 1 1.5 1.49
-55.123 -55 -55.1 -55.123
9810 9810 9810.0 9810.00

Notice that when the format string has fewer digits to the right of the decimal place than the value, then the value will be rounded accordingly. We also support scientific notation:

x ${x?string(“0E0”)} ${x?string(“00E00”)} ${x?string(“0.0##E0”)}
0.9 9E-1 90E-02 9.0E-1
1.49 1E0 15E-01 1.49E0
-55.123 -6E1 -55E00 -5.512E1
9810 1E4 98E02 9.81E3

We hope this system makes it easier for you to run design of experiments on Rescale.

The security of customers’ information is of utmost importance to Rescale. While many of the steps we take to protect customers’ information are outlined on our Security page, new customers may have doubts about the effectiveness of the systems and controls we provide to protect their data. That’s where a trusted third-party can provide some reassurance. Our team here at Rescale recently brought in an independent auditor to perform an objective review of the controls Rescale has in place, to ensure that customers’ information is stored in a secure manner and available when needed.

We elected to pursue a Service Organization Control (SOC) 2 report as defined by the American Institute of CPAs® (AICPA®). The SOC 2 report addresses the following key features of a system, which in Rescale’s case is the cloud engineering simulation platform:

The system is protected against unauthorized access (both physical and logical).

The system is available for operation and use as committed or agreed.

Processing integrity
System processing is complete, accurate, timely and authorized.

Information designated as confidential is protected as committed or agreed.

Personal information is collected, used, retained, disclosed, and disposed of in conformity with the commitments in the entity’s privacy notice, and with criteria set forth in Generally Accepted Privacy Principles (GAPP) issued by the AICPA and Canadian Institute of Chartered Accountants.

There are two types of SOC 2 reports, appropriately named Type 1 and Type 2. A Type 1 report describes the controls that are in place to address the features described above, along with the auditor’s opinion on the adequacy of those controls. A Type 2 report includes all the information in a Type 1 report, as well as a list of tests the auditors performed to verify the controls and the results of those tests. Examples of the tests performed include, reviewing a log file from a randomly selected date to verify that an appropriate audit message was recorded, reviewing third-party uptime evaluations, or verifying that a customer issue was appropriately tracked from the initial report to resolution.

Rescale received its Type 1 report from an independent auditor in June of 2013, and its Type 2 from that same auditor for the period from June 1st to November 30th. Going forward, Rescale will have annual audits to ensure that customers know a third-party organization regularly reviews the controls in place to protect their information.
