|How to Troubleshoot Dual-Core and Quad-Core Central Processing Units (CPUs)|
| by rpanic in Computers|
Dual-core and quad-core central processing units, or CPUs, contain multiple
cores, or independent processors, that read and perform program tasks. As
the names suggest, dual-core CPUs contain two cores and quad-core CPUs
contain four cores. Multi-core CPUs are both more powerful and efficient
compared to single-core CPUs, but still fall victim to some of the same
problems that single-core processo
|Core Plot:Memory Issue Core animation failed to allocate so many bytes|
| by jasonmoo in Operating Systems|
I am using core plot for generation various types of graphs using
webservices.But after generating around 60 graphs the graph scren appears
to be blank giving a message in the device log as "Core animation failed to
allocate 9997432 bytes"
we are facing this issue only on the device
where as the app runs fine on simulator.
The following is the
code snippet,We are passing data t

|Core Plot Scatterplot with bindings not shown when opening Core Data document file|
| by Thyrius in Development Tools & Services|
I have a
NSPersistentDocument-based Core Data application.
There is an array of data I can edit in the document, and I want the data
to be displayed in a Core Plot graph. I bound a
to an ArrayController that is connected to the respective entity.
Almost everything works: The plot is updated every time I add a new data
point or edit one. So I guess I
|Does Visual Studio 2010 benefit from quad core vs dual core machines? Is compilation multithreaded?|
| by Mansur in Network & Servers|
I have a Windows XP machine with a dual core 3.6G CPU and 4megs. I am
not very happy with the performance. I was wondering if compilation in VS
2010 is multithreaded and does VS 2010 benefit from switching from dual to
quad core machine?
|Creating animated containing circles with Core Graphics and Core Animations|
| by DrMrLordX in Operating Systems|
I'm trying some time, but without success.
I made some circle with
animation that I want. It animates from radius 23 to radius 7.
There is a code that's working fine, but without
transparent circle in it.
I need help to get this "transparent
inner circle" working during animation.

|Cocoa 2D graphics: Quartz, Core Image or Core Animation?|
| by UglyCasanova in Programming Languages|
I have been reading for several hours now documentation about drawing
two dimensional graphics in a objective-c cocoa application. There appears
to be several different technologies all specific to certain tasks. My
understanding is that the following technologies do the following things.
Please correct me if I'm wrong.

|What Is the Difference in Speed in Quad Core & Single Core Processors?|
| by Per in Computers|
As CPU (Central Processing Unit) manufacturers developed smaller internal
processing "cores," it became possible to put up to four processing cores
into a physical CPU package that had previously held only one. This
improved overall performance, but not necessarily by a factor of four.
Single-Core CPUs vs Multi-Core CPUsCPU manufacturers "hit the wall" around
4 GHz. At that speed, heat and powe

document with sample codes.
Thanks in advance.
|The AMD Athlon II X4 620 Quad Core Processor vs. the Pentium Dual-Core|
| by PrinceMyshkin in Computers|
The AMD Athlon II X4 620 is a desktop entry in the Athlon II brand of
processors designed to supplement Advanced Micro Devices' top-level Phenom
brand. It was released in 2009, coincidentally the last year of production
that rival semiconductor manufacturer Intel Corp. branded its mid-range
central processing units as "Pentium Dual-Core." The desktop processors of
this brand consist of the E2000 a
