Sequalator 1.20.2 Released

2015-01-18T20:37:00.001+05:30

Splash screen at start-up - The recent enhancements have increased the start-up time significantly and so, it takes some time for Sequalator main window to appear after the application has been launched. So, by the time it loads all its components, Sequalator icon will now be displayed until the main window appears. This is a necessary enhancement to provide proper user experience.

Bug fixed - A minor bug was reported by one of our users in the community. The benchmarks for stealth mode were poorer than the simple User Interface (UI). This bug has now been resolved and accordingly the bug tracker is updated to close the bug.

Analyse dialog UI improved - Previously the dialog used to show 0 for the solution set from file even if there was no solution set saved in the file. This has been corrected so that now, if there is no solution set saved in the file, it does not show any value in the dialog. Accordingly some options are updated in the dialog.

Sequalator 1.20.1 Released

2014-09-06T23:53:00.002+05:30

Automatically check for updates - Sequalator now has the capability to automatically check for updates. It will check only when Sequalator is launched and that too only the first launch of that day. Thus you are assured of getting the latest features of Sequalator without bogging down your PC by an updater running in background.

Bug fixed - A minor bug was reported by one of our users in the community. Sequalator was not saving the benchmark file even after specifying the path. This bug has now been resolved and accordingly the bug tracker is updated to close the bug.

Solver selection improvement -You can now very easily choose the solver for your computation. Previously there was a lot of confusion between the default solver and the OpenCL solver. The User Interface has been revamped to allow the user to choose the solver for running the computation.

GUI enhancements - Some minor improvements have been made in the GUI which will enhance your experience with Sequalator.

Installer support - Sequalator now has an installer! No longer do you have to go through the mess of zip files. Just launch the installer, next, next, next, finish and you are done! But don't forget to read the instructions on each page. :)

No software is without bugs i.e. faults. Sequalator has its own share of bugs. Please report them! Just send in your e-mail along with some details about the bug.

How to perform Sequalator benchmarks?

2014-08-01T22:49:00.001+05:30

The cardinal reason for using Sequalator compared to its alternatives is speed and precision.
But how do you know how fast Sequalator really is?
Well, that is why you benchmark Sequalator!
Performing benchmarks with Sequalator is really easy and there is a prize too!
The top 10 benchmarks will be posted on this blog under the Benchmarks page!
Just follow these really simple steps to complete your benchmark:

1. Start a fresh session of Sequalator and open the Options dialog (Tools -> Options)
2. Go to User Data -> Main Window. Now disable Hardware Acceleration using OpenCL and press OK and again press OK if the confirmation dialog appears.

3. Again open the Options dialog and press the Benchmark button. Enter the no of variables as 2000. Set the User Interface to Stealth Mode. Select the File type as Binary File. Now press Start!

4. After the benchmark is complete, Sequalator will ask if you want to save the benchmark file. If you want to have a copy of the equations used for performing the benchmark then press Yes; otherwise press No.

5. Now take a screenshot of the Options dialog and save it to a file. The best way to do this is by pressing Alt + Print Screen buttons simultaneously. Open MS Paint -> Ctrl + V -> Crop -> Ctrl + S (Select the file format as PNG).

6. Press the User Data button and enable Hardware Acceleration using OpenCL (disabled in step 2). Press OK to close the Options dialog.

7. Open the Options dialog and press the Benchmark button. Enter the same values as entered during step 3 and press the Start button. After some time a dialog similar to the one as shown below will appear:

NOTE: If your PC does not have a GPU or if the OpenCL drivers are missing you may not get this dialog at all. If so, then your benchmark is almost complete. Go to step 9. Otherwise save a screenshot of this dialog to a file.

8. Select the device no 1 and press OK. This will perform computations on the corresponding device.
When the benchmark is complete take a screenshot of the results. You may want to repeat this step until you get benchmark results for all the listed devices sequentially.

9. You now have all the screenshot files ready to upload. Just go to the Sequalator discussions group. Press the New Topic button. Make the subject of the discussion Sequalator Benchmarks by your name. Add details as per this format. After adding all the required details submit the topic.

10. You will be notified after your benchmark is reviewed.

OpenCL support - OpenCL (Open Computing Language) is a standard for cross platform parallel programing using modern computation devices like CPU, GPU, etc. Sequalator now can solve the equations on multiple devices like CPU's and GPU's simultaneously using the power of OpenCL technology. To use this feature however, you need to register your copy of Sequalator, which is absolutely free! OpenCL and the OpenCL logo are trademarks of Apple Inc.

64 bit support - Sequalator is now available in 64 bit version as well. This means there is no 2GB memory restriction which is applicable to any 32 bit application. So if you have the sufficient RAM and processing power there is virtually no limit to the no of equations you can solve using Sequalator. Also note that 32 bit applications will work on 32 or 64 bit hardware, but 64 bit applications will only work on 64 bit hardware.

Bug fix - A bug reported in the previous version has now been fixed. The cause of the bug was a minor programming mistake (we all do ;-) ); to be precise Sequalator was trying to read a non existing file.

GUI enhancements - There have been quite a lot GUI enhancements in this version. This is primarily because Sequalator now uses Qt 5.2.1 while all previous versions used Qt 4.8.1. This version of Qt has had a lot of bug fixes and apparently highlighted some of mine too :P

No software is without bugs i.e. faults. Sequalator has its own share of bugs. Please report them! Just send in your e-mail along with some details about the bug.

Bug found in Sequalator 1.19.0

2014-03-22T12:27:00.000+05:30

A bug in the latest release of Sequalator has been observed.
Work is ongoing to repair this problem and until that time Sequalator 1.19.0 will not be available for download. Users are requested to continue using Sequalator 1.18.2 on a temporary basis. The bug tracker is updated with a record of this bug. Below are the details of this bug:

After launching Sequalator an error message is displayed as shown below.

After clicking OK, a window shows the error report for that session.

Open the session.log file to see the error type.

The error message we are getting signifies that a non existing file was trying to be read. This file records all the existing sessions and the non availability of this file requires termination of the application.

As of now work is ongoing to find a solution to this problem and the fixed version will be released as soon as possible. Inconvenience of the users is regretted.

Binary File Format - A new file format is now added to store the data in a compact and robust manner. Not only does it use less space compared to the text file format, the time required to create this file and read data from the file is also significantly low.
Session Manager - The session manager saves a record of every action you perform to a file. This means your data is still safe even if you close Sequalator without saving the data. In addition if at all you experience a crash, you can still retrieve just where you left off!
Revamped Undo Redo functionality - The undo redo functionality in previous versions stored the action history in memory (RAM). In this release the entire undo redo functionality is re-written so that the action history is stored to file. This is possible now because of the binary file format which is light years ahead of the text format in terms of speed.
Apart from the above mentioned enhancements there are quite a few changes in the GUI.

Sequalator 1.18.0.0 Released

2013-11-16T23:01:00.000+05:30

This is the first public release for a software being developed over a period of 10 months. But before I talk about what it does let me first explain the meaning of this strange name.
Sequalator stands for Simultaneous Equations Calculator.
As the name suggests it is a Linear Simultaneous Equations Solver.
In its current form it can tirelessly tackle thousands of Equations, with a very high precession.

The Graphical User Interface (GUI) is built using Qt.
Qt is an awesome application development framework if you love C++ & want to have complete control over the most basic functionality of your software.
It is pretty intuitive and easy to use, plus their documentation and online forum are extremely helpful.
That being said it comes with the generous GNU LGPL license!
The underlying algorithms in Sequalator for solving the equations are based on Gauss Jordan Elimination technique.

This project was born out of my desire to learn Qt and now after a period of 10 months it seems truly unbelievable what I have achieved.

The journey is the reward

Since I learned so much from the community for free, I decided to license this application without any fee.
Sequalator is free software.
You may use it for educational as well as commercial purpose.
You can download Sequalator from the Downloads page.
