SREA Acquires $75 Million Dollar Asset!

Score One Inc.(SREA)
$0.30

News hit just after close. SREA has acquired the $75 Million peace of
land for the new "Recreation Town" in Dalian. This new project mimics a
Facility in "Shui On" that profited more than $100 Million USD. SREA is
going to go through the roof after this hits investors this weekend. Get
on SREA at open on Monday!

The application is then built as described above; in this case low
optimisation is used because at higher levels of optimisation the entire
program will be eliminated.

At any point in the execution of any application, Java or otherwise, the
callstack represents where the program is in its execution, and how it
got there.

A Java program is inherently multithreaded, and has one JVM thread for
each thread in the user's Java program. In an ideal situation, the most
frequently executed basic blocks in the training workload will also be
the most frequently executed basic blocks in the reference workload.
Profiling Startup Time of an Application  Either mechanism can be used
to look at the startup time of an application. Concluding remarks This
paper has presented several methodologies for determining if a
particular training workload is appropriate for a particular reference
workload.

One particularly useful strategy to use is to set it to match all
methods in a class or set of classes.

Java programs may have explicit synchronization, usually performed by
calling the monitor-enter routine. Then, select a color, and then select
the algorithm to be used from the option menu initially labeled "Starts
with". In this particular case there is no report to produce as the
output is produced during the run.

c program is used to show the proper usage of both DTrace and the Sun
Studio dbx debugger.
The syscall provider enables you to trace every system call entry and
return. Java callstacks, as reconciled, are shown in the Java
Representation, and in the Expert Java Representations if they were
captured for the event. Before joining Sun, Darryl held various software
architecture and development roles in the UK. Java always uses bound
threads, so that there is a one-to-one correspondence between threads
and LWPs.

A more advanced analysis tool might look at cache misses that the
application encounters for a given cache structure. This routine writes
the disassembly of the instruction into a buffer. The special identifier
self is used to define the thread-local variable start. In this case we
will call the analyzer 'trace' and there are no user configurable
parameters. The callstack shows JVM frames, native frames, and
compiled-method frames.

You can set all its methods to one color, all the methods from com.

The following is a step by step walkthrough of the process of gathering
the data for either the training or reference workload.
To use this functionality, bring up the Analyzer on an experiment,
select the Timeline, and then bring up the color chooser. If sample
markers are used, the data volume will be higher, but you can filter by
sample to look at any part of a run, even parts you thought would be
uninteresting when the data was recorded.
Methodology The methodology proposed here is to gather both basic block
count and branch probability data for the training and reference
workload. The lines command shows exactly which lines in the source code
consumes the most CPU time.
During execution, there may be many instances of a particular java
method executed, the interpreted version, and, perhaps, one or more
compiled versions. The function list in the Java representation shows
metrics against the Java methods, and any native methods called. It also
lets you monitor memory usage.

The second thing that they do is that they record, into the trace
record, what happened as they executed the code. An emulator is software
which 'pretends' to be a processor; so that the application runs on the
emulator, which then runs on the real hardware. Signal-control of Data
Collection The Sun Studio Performance tools provide mechanisms for
controlling the data collection from an application by using signals.
Native callstacks are shown in the Machine representation, and in the
Expert Java Representation if a Java callstack was not captured for the
event.
You can set all its methods to one color, all the methods from com. The
Performance Analyzer displays the detailed information about each LWP.
All functions from the JVM will be shown as such.

In the current release, clock- and hw-counter-profiling, as well as
synchronization tracing are supported. Access errors might result in
wild pointers in the program and can cause incorrect program behavior
such as wrong output and segmentation violation. This routine writes the
disassembly of the instruction into a buffer. For performance reasons,
the analyzer gets a block of records from the SHADE library. Similarly
assume that Ri is the number of times that basic block i is executed
during the run with the reference workload.

It also displays the time that it takes to run each individual thread.

This information enables the compiler to make better optimisation
decisions. Building the trace tool The complete source code for the
example appears at the end of this article.

Source from compiled methods will be shown against the Java source; the
data will represent the specific instance of the compiled-method
selected.
Native callstacks are shown in the Machine representation, and in the
Expert Java Representation if a Java callstack was not captured for the
event. so     Reading libdl     Reading rtcaudit.
so     RTC: Enabling Error Checking. The analyzer has to be written in
order to take the trace generated by the SHADE library and analyze it.
It is possible to calculate coverage as a single value. These snippets
do two things, first of all they do the same thing as the original
application would have done. The User Representation  The User
Representation shows compiled and interpreted Java methods by name, and
shows native methods in their natural form. In this particular case
there is no report to produce as the output is produced during the run.
For instance, the lwptime. Using other specifiers it is possible to
record other data, such as the effective address of memory operations.
A workaround to support profiling for such an application, is to not set
-j on for the initial collect invocation, and to ensure that the
-Xruncollector option is passed to the invoked JVM.

Profiling Steady-state Behavior of an Application  Either mechanism can
be used to look at the steady-state behavior of an application. The
SHADE library does all the work of emulating the application, once it
has gathered a trace of instructions, it hands this trace over to the
'analyzer'.
