LinX - A simple Linpack interface

[Duh]

Due to Duh's generousity we now have a new hosting for LinX.

From now on the main download link is this: imagepedia.net/datajay/linx.zip
The FileDen link remains working, it just won't be updated anymore.
Dropbox link (2nd one) remains the same.

Btw, didn't anyone notice a performance decrease (GFlops-wise) in the 0.5.9? A guy at overclockers.ru reported a pretty huge drop of ~1GFlop on x32 version. Can anyone confirm this?

My pleasure dude, thank you for helping the community ! unless I get over 70Gb of traffic I will leave it there for unlimited time . I am planning to set up a server in a virtual environment with a (heavily) shared 100mbit pipe

This program looks GREAT, as soon as my rig is back in action I will be using this to stress test.

Good work

Is there a plan for a Linux version of LinX? How did you get around the 50% cpu usage on Windows. On Linux, the linpack executable only used 4 cores although it reported 8 CPUs and 8 threads.

A Linux version would be cool! I will likely write one if you don't... Imagine running this from a linux livecd. No more lost filesystems or chkdsk!

Thanks! If everything goes well, it's gonna be even better.

Answered in PM. I'd like to write Linux version too, but not sure if I'm skilled enough for that right now.

Hey this is an awesome prog!! Love it.
TWO questions-

1) is it wise to just leave "problem size" at whatever the app sets it to (which seems to change depending on amount of RAM selected) ? I assume "YES" to this.

2) I can't seem to get the "create graphs" thing to work- am I missing something? I have Everest running (see icons there in the tray, screenshow below) but the option is greyed out:

A Linux live CD version for stability testing would be awesome!

1) Problem size and memory are actually almost same things, just in different measuring units, sort of. So when you change one, another is changed too. That's ok.

2) You also need to enable shared memory in Everest's settings. (External applications -> tick Enable shared memory).
After all, there's somebody who's using this feature...

Yes, but the author is somewhat a n00b, so it'll take time. Sorry.

Sounds like the ultimate dream for o'cers!

LinX 0.6.0 has been released!
Same link.

Where?

Stop spoiling.
Lol. I just wanted to make sure there are no major bugs prior to announcing it here. Sorry for this delay, guys.

All right, here it is, the 0.6.0 version.


LinX 0.6.0 changes:

- added setting to change Linpack's priority
- removed restriction to maximium number of threads (formerly equal to the logical CPUs number)
- tweaked (rebased) the libiomp5md.dll for a higher possible Problem size of 32-bit Linpack
- added setting to add date/time to saved files (logs & screenshots), on by default
- changed progressbar to look the same on all OSes and consume less resources
- main menu changes/simplifications
- command-line keys added (experimental), for the list of available parameters launch LinX.exe /?
- some interface changes and optimizations
- easter-egg added

Mirror link is working, main link (and 1st page) will be updated soon.
Hope you'll like it.

No problems, man. It's the same version, only in Russian (can be made English by deleting the local.lng file though).

[ChaosMinionX]

Whats the easter egg?

[Dua|ist]

Done, 1st page updated, links for 0.6.0: LinX.7z or LinX.zip.

It'd be great if anyone on Vista or Win7 with 3+ GB of RAM could check the maximum Problem size for 32-bit Linpack now after that dll tweak (should be a bit higher). Just edit the Linpack32 max Problem Size setting till it starts saying in its log that there's not enough memory. Thanks in advance.

Well, it's an easter-egg. It just won't be fun if I tell you that straight. I'm sure someone will eventually find it. For now all I can say is that it exists and that it is completely useless but somewhat cool. But not on XP. (This can be considered a hint.)

I'm wondering if there is a reason for huge differences in gflops values between different runs.
I run a E8400@4Ghz and i get very different values between runs:
When it works like it should I get around 28.5gflops and high temps on my cores but sometimes the test runs at half speed and it does only around 15gflops and temps are 10 degrees lower.
I have decent temps so it's not thermal throttling and linpack uses 100% cpu load...

[Cyber-Mav]

could be hitting page file thats why i select max memory and then back off by 50mb and then let it carry on testing.

[slim142]

Dam XP x64 here so no easter egg for me.

What you describe is probably my fault completely, but I'm not sure yet. I'd be grateful if you could try this version and report if you still get that strange behavior or not. Same goes to all having this issue. (Should be a lot of people )

Windows7 soon will rule the PC world. But maybe I'll do another easter-egg for XP users. Once the serious stuff gets fixed.

"Linpack has stopped unexpectingly. Press the ">>" button for details"

I might be blind, but where is the ">>" button? I cannot find it anywhere on the UI, and I don't have it on my keyboard either!

It's located near the bottom-right part of the program.

Weird, I dont see it on my copy running under Windows 7 x64 B1
