LinX - A simple Linpack interface

Very nice prog. thank you.


The only question i have.

To test stability of the System must i set something once started the program or i just start it and only set the number of tests to run ?

It will be great if you explain if there are some settings to perform.

Thank you.

The most common settings that you might want to set manually are in the main window : Problem size and corresponding amount of memory and number of runs.

All other Linpack settings can usually be left as they are, LinX automatically enables 64-bit Linpack on 64-bit OSes and sets number of threads equal to the number of logical cores. Data Alignment and Leading Dimensions settings don't have much (if any) impact on testing/performance anyway, but by default they're also set to Intel's recommended values.

Advanced settings are there just to tweak consumed memory formula in case Linpack fails to start with no memory message, no need to tweak these if everything works ok.

Everything else is just LinX own settings. Their default values are also suitable for most cases.

There are hints to almost every setting, but if something is unclear, feel free to ask.

Thank You (Спасибо) !

Ok everything works fine, no changes made since first start.

What does Problem Size affect ?
What happens if i select Bigger or Smaller Problem Size ?
