Address Space Monitor


Address Space Monitor is a simple utility to monitor a process’ use of its address space.  To begin monitoring a process, choose the “Process|Attach …” menu option and type in the process id of the process to be monitored. The “Attach to process” dialog box now features a process browser so that you can select the process by name.

Alternatively you can choose to spawn a new process. If you select the “Process|Run…” menu option you will be presented with the “Run” dialog box. From here you can browse for the executable file for the process you wish to start and the initial working directory for the process. You can also enter in any required command line arguments.

While monitoring a process, the display is split into three sections.

The top section shows the address space of the process in a gauge format, from low addresses (close to zero) on the left, rotating clockwise to high addresses (2GB for 32-bit processes, 8TB for 64-bit processes) on the right.

Free address space is shown in green, reserved addresses in yellow and used (committed) memory regions in red.

The next section of the display shows the largest free regions of address space as colored ellipses in descending order of size. The full width of the display represents a quarter of the total address space for the process (about 512MB for 32-bit processes, about 2TB for 64-bit processes) and large regions are shown as half an ellipse covering the full width of the display even if they exceed half the total address space.

The regions are colored according to their upper address so that they can be tracked as their lower parts are used up. Low regions start from yellow, going through magenta at half way, to cyan at the upper end of the address space.

The final section has some textual summaries for the address space.

The first number is the total amount of committed address space for the whole process,  the second number is the total amount of reserved address space for the process, the third number is the total amount of free memory and the final number is the size of the largest free address space region.

For committed and reserved regions these totals may be larger than what you might expect from looking at other memory analysis tools as all address space is counted, including mapped files and shared memory regions, rather than just regions which are mapped to physical memory or swap file space.

The utility has most use for 32-bit processes as 64-bit process tend to be dominated by a very large (only fractionally smaller that 8TB) region of free address space from the 2GB boundary upwards.

Address Space Monitor now supports recording both single snapshots of a process’ address space as well as recordings of a process’ address space over time. A snapshot can be recorded through the “File|Save as…” menu options, and redisplayed through the “File|Open…” option.

A recording can either be started through the “File|Record…” option or, when creating a new process, by selecting the “Record” check box in the “Run” dialog box and browsing for the name of a file to record. In both cases the recording will stop when the process being monitored exits. While recording the “File|Record…” menu option will display a tick icon. The recording can be halted manually by reselecting the “File|Record…” menu option while the menu option displays a tick mark.

Performance Test with BlackBox


Now we getting somewhere!.  I hope you followed the Checklist , so it’s time the run a Hardware test. What we gonna do is testing the Processor, Memory, Graphics, System and make a Benchmark of the results.

Here we go. First pick up a nice piece of software HERE and select the 32 bits or 64 bits version. Install the software and GO!

This is what is looks like; BTW, I over-clocked my i7-920 from 2.6 to 4.0
(REMINDER: TAKE CARE OF THE COOLING !!!)
