default install and run on ubuntu system presents "FAIL" about stressapptest HOT 12 CLOSED

have the same issue on ubuntu 9.04
Linux 2.6.28-15-generic #52-Ubuntu SMP Wed Sep 9 10:49:34 UTC 2009 i686 
GNU/Linux

Note that the reported error also reports the workaround, namely to add "-A" to 
the
command line options to ignore the fact that the program either does not 
support or
cannot determine the OS version.

I suggest there are two bugs here:

1. That a modern ubuntu system is not detected or supported

2. That the default behavior is to abend, instead of noting the lack of support.

-alan

Start with flag -A :

$ ./stressapptest -A

where -A means "run in degraded mode on incompatible systems".

This is as expected, since IsSupported() in os.cc always returns false.

I have the same problem.

I am using version " revision 1.0.0_autoconf, 32 bit binary" on an Ubuntu
LInux OS.

I ran with flag -A and I got:

I think there are a couple issues here: 
* -A is not useful as an argument, as no specific systems have support.
* Explicit buffercache flush may be necessary to free up memory.
* Explicit fail when swapping to disk (dixlor, it is likely that you are 
swapping)

'-A' argument is no longer required in 1.0.1

Is there any windows version available?

@Comment 8: use a unix based operating system, or if you must: use a virtual 
machine.

@Comment 8 
No windows version is planned in the near future. You can boot with a usb key 
linux
distro or a standalone boot dvd, and run stressapptest without any permanent 
linux
install. 

Original issue of FAIL without superfluous '-A' arg fixed.
