Hi all,

we wanted to add some information to the discussion about the CPU, RAM, Disk
and Graphics card. We cannot speak for acquisition software requirements but
only for analysis software needs.
All that Oliver Biehlmaier said about CPU, RAM etc. applies also for most
cases in Imaris. If the data and derived data fit into the RAM (rule of
thumb ten times the amount of RAM of the raw data set) the CPU speed will be
the limiting factor as well as the core count. Imaris is in many parts
multithreaded since Version 6.3 from IO operations to image filters. But you
can still get the impression that it uses only one or two cores as some
parts are not multi-threaded which may dominate the execution time. We
continue to make additional functions multithreaded like in the latest
version the distance transformations and diameter calculation in Filament
Tracer. However, to come back to Oliver’s post; our current hardware
recommendation for Imaris in general is:
- get a fast 4 (6) core processor (with hyper-threading). This is currently
the sweet spot in price-performance ratio; Imaris is making good use of this
8 or 12 threads;
- enough RAM; about 10x of the raw data set size to fit the data set and its
analysis into RAM;
- if possible get a fast SSD only used as Imaris cache drive (for cases
where the data set would not fit into the RAM); at least 10x the size of
your typical raw data set size;
- Get a high-end gaming graphic card (nVidia or ATI); unless you want to do
stereo 3D with shutter glasses in which case nVidia Quadro card is required.
Our take home message is: keep your CPU fed with data as fast as possible!

Dear all,

this seems not to be a proper confocal question but I know your great
expertise could help me in solve this as the IT couldn't.....

I am trying to recover the informations of logins on 2 computers in our
facility ( to compare the real usage of the system). Both computers run
on Windows7 and the Event viewer I can visualize do not contain the
information on the name of the user logged in. As for Login user the
system gave to me the name of the computer and a $ close to that.

I managed so far to have the Event viewer working on all the Windows XP
systems, but it seems Windows7 works in a different  way.

Thanks in advance for all your useful replies.

Hi Valeria,

The windows 7 event viewer is different than XPs viewer.  I have been unable to turn on a column to show users.

However, the users name can be found in the Details tab of the Security log.  Check on Logon events, some of them near the end of the logon process will have the users name.  I find that it is easier to look at Logoff entries, as it is easier to find the users name there, then I go back to find the time of the login.

I hope this helps,

Lon

Hello Valeria,

For logons only I've used the guidance here in the past:
http://msmvps.com/blogs/kwsupport/archive/2005/02/24/36942.aspx to create a
log locally on each of the microscope computers by setting the location to
save as D:\directory\log\log_on_off.log (for example). It works nicely if
you just need a reference for who has been using you microscopes.

My computer guys then helped do this at the server level (Samba; logon.bat)
running a logon script for domain users, which looks like:
-----------------
echo Login From: %COMPUTERNAME%, User Name: %USERNAME%, Date: %DATE%, Time:
%TIME% >> \\server\directory\logs\logons.log
-----------------

So, every users that log into the domain will have the logon information
captured. As an example the log file will look like below and I can open it
on any computer with access to the server. I can then search for the
computer name I want to know about (as we have about 20 computers, mostly
running XP)

------------------
Login From: SELETAR, User Name: darren, Date: Fri 01/11/2013, Time:
19:01:47.62
Login From: PALAWAN, User Name: yuezhen, Date: Sat 01/12/2013, Time:
 9:54:44.65
------------------

This works well as no configurations need to be done on the windows domain
clients.

To capture log off information has proved trickier and we are still trying
to find the best workaround for that. Fortunately I don't need that
information at present.

Regards,
Graham

I had previously written some AWK scripts to pull out all the needed logon/logoff information from a "Save Log File As…" export of the Security Log Events file from our Windows XP computers, but as noted in the post from March, Windows 7 Logfiles have very different structures, so the AWK scripts no longer work.

However, I have very recently been testing the PowerShell script at:
http://gallery.technet.microsoft.com/scriptcenter/Log-Parser-to-Identify-8aac36bd

(FYI Description of security events in Windows 7 at http://support.microsoft.com/kb/977519)

It seems to work quite well on Windows 7 (and probably on Windows XP as well), and when you choose the "Table" option when you run the script in PowerShell, it produces an onscreen table of all Logon and Logoff events (and not all the system and network logon/logoff events) that you can select and paste into a document; alternately, you can modify the script to produce a file output automatically when you run the script - and no need for any other additional AWK or other scripts.

Sorry for the long delay since the original post back in March, but have just been testing this recently and hope that this PowerShell script might still be useful to people.
