Hello all,
I'm looking for some input on the best tools to use for profiling
multithreaded C++ code developed on GNU/Linux and compiled using
gcc-3.1. More specifically, the distro in use is RH 7.2 running
kernel 2.4.7 with SMP. The box has dual processors.
Some of the options I've found are
gprof - standard GNU profiler that comes with gcc. The biggest
problem with this is that it does not support multithreading or

Hi there,
I have some scientific application written in python. There is a
good deal of list processing, but also some "simple" computation such
as basic linear algebra involved. I would like to speed things up
implementing some of the functions in C. So I need profiling.
I first tried to use the default python profiler, but profiling my
application multiplies the execution time by a factor between 10 and
100 ! So I decided to give a...

Hello All,
I'm trying to profile a Python program using gprof,
but I don't understand some of the results, especially
what some of the functions do. For example, _moncount,
mcount, _PyEval_EvalFrame <cycle X> take too much
time. What are they for? Any ideas?
Thank you for your help!

dear
I need to know the execution time of the program. Below is just an
example. I used to use gprof. But in this case, the error messsage says
"gprof : gmon.out file is missing call-graph data".
Is it possible to 'gprof' with this ? Or it will be nice if someone
introduce how to measure execution time......
Thankyou for comment.

I've got Visual C++ 2003. I'm looking for a profiling tool. I'm from the
Unix world where a good profiler comes free and built into the compiler and
linker.
I tried the Help utility in Visual C++ and got 500 hits for "profile" .. but
none of them indicated that a profiler is built-into Visual C++.
Question: Is there a profiler built into Visual C++ 2003? If not, can any
one recommend a free profiler?

Hello,
I want to apologise in advance for this being off topic. It's not neither
A C nor a C++ question, but to profiling in general, though I my chances
are best to find the answer in the C/C++ community.
I have a C++ program to profile and went about it by producing large
history files of calling dependencies with associated times. It is
presumably similar to gprof's data format and could be converted.

Hi,
I want to profile a C program I am writting, so I compile it with -pg
options and use gprof to obtain information about call graphs, which I
am really interested in. I look at the text files but when I have a
large number of functions, it looks really embarrasing. So somebody
recommended me about graphviz. My problem was to find something to
convert between gprof format and graphviz .dot format. I finally found
gprof2dot.py and ...

I have used gprof to profile stand alone C++ programs. I am also
aware of pure python profilers. However, is there a way to get
profile information on my C++ functions when they are compiled in a
shared library (python extension module) and called from python. From
what I can tell, gmon.out will not be generated unless the entire
executable (python interpreter) was compiled with -pg. Is my only
solution to recompile the python...

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:

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,...
