Hello!
I am a c++ programmer under the os linux. I am using pthreads and i am
wondering why i can only use satic methods of a class to create a
thread of it. How can i change this, because it limits my programmes
very strongly. thanks in advance..Arnd Schröter

say, if you had parallel arrays containing the sales person id, the month, and
the sales figures (for that person in that month), sorting on sales figure and
preserve the order of figures within the data about the same person:
Original Data:
id month sales
+-----+ +-----+ +-----+
| 432 | | 8 | | 89 |
+-----+ +-----+ +-----+
| 123 | | 8 | | 116 |

When the POSIX pthreads library for w32 release 2-2-0
(http://sources.redhat.com/pthreads-win32/) is compiled with VC++6
then it compiles and passes all the benchmark tests in the subdirectory "tests".
Also, VC++ 2005 beta 1 compiles the tests fine, but here the following
tests fail in execution:
# semaphore1.pass \
# condvar2.pass \
# condvar2_1.pass \
# mutex8.pass \

Hi friends,
I need to write a parallel code in 'C' on the server that is
running SGI Irix 6.5. This server supports MIPS Pro C compiler. I don't
have any idea of parallel C languages. I looked into few posts in this
group. I could make out that there are several languages for parallel
programming and parallel C is one of them. I need to know if this is
supported by MIPS Pro C Compiler. Or are there any other parallel C
languages that have...

Has anybody tried to run parallel python applications?
It appears that if your application is computation-bound using 'thread'
or 'threading' modules will not get you any speedup. That is because
python interpreter uses GIL(Global Interpreter Lock) for internal
bookkeeping. The later allows only one python byte-code instruction to
be executed at a time even if you have a multiprocessor computer.
To overcome this limitation, I've created...

Hi,
I'm working on a program that takes the following input from the user:
Student Name, Student Number, and Student GPA
The information is then supposed to be stored in three separate arrays.
Prior to sending the output to the screen, a bubble sort has to be performed
so that it's sorted by Student Name.

If you're using user-level threads (e.g. pthreads) and doing synchronous
I/O then it's likely that the whole process is being blocked by the
kernel until the I/O system call returns. To be honest, on a
uniprocessor system you're not likely to get much help from threading in
the situation you describe, even if you do complicated things to get
asynchronous I/O.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
