How do I figure out whether my process is CPU bound, I/O bound, Memory bound or
by Wild Thing in Operating Systems

I'm trying to speed up the time taken to compile my application and one thing I'm investigating is to check what resources, if any, I can add to the build machine to speed things up. To this end, how do I figure out if I should invest in more CPU, more RAM, a better hard disk or whether the process is being bound by some other resource? I already saw this (How to check if app is cpu-bound or me

A fast data structure for lower bound and upper bound queries on integers?
by pad in Programming Languages

i have to maintain a list of numbers, count up to 100,000...

if the data is (for example)

1, 4, 9, 12, 20, 35, 52, 77, 91

and i query for a number, say 27, i want the number just immediately previous to 27, available in the list, so that will be: 20

the data is also going to be modified frequently, like lots of Inserts and erases.

error in updating data in bound datagridview (bound automatically in designer view)
by South Korea in Programming Languages

I have a datagridview in vb.net that is bound to a datasource. I did this in design view, and I wanted minimum coding.

So without any SQL, I did the following steps:

Added a datagridview from the toolbox.
Added new project datasource (this datasource, AllDB_dataset has a lot of tables).
From the little arrow created on the top of the new datagridview,

Bound Property always returns false but WPF bound CheckBox is still checked
by Verbal in Databases

I have a checkbox in a UserControl:

<CheckBox Content="Existing" IsChecked="{Binding Path=IsExistingTemplate, Mode=TwoWay}"/>

It is bound to a DataContext with Property IsExistingTemplate which always returns False. (In my real application, it doesn't always return False!). DataContext implements INotifyPropertyChanged.


Can a Java Generic Using a Bound Parameter be Instantiated with its Upper Bound?
by xes in Java

For example:

class MyClass<T extends MyClass2> {
// Do stuff...

Then later:

MyClass<MyClass2> myClass = new MyClass<MyClass2>();

Does this work? My coworker's hunch is no, but I can't find anything to confirm that for me and the documentation suggests perhaps.

How to Find Upper Bound & Lower Bound on Excel
by krs in Computers
The upper and lower bounds of an Excel array determine how many values are contained within the array variable. The Excel VBA language has the "UBound" property and the "LBound" property that returns the number of values in the array. You use this function in any of your Excel VBA programs.Difficulty:ModerateInstructions Right-click the XLS or XLSX file you want to edit and

Can I get the Type() of a bound object in C#/WPF (even if the bound value is null)?
by MikeG in C & C++ & C#

I have a binding to an unknown source. All I have is the binding. I have no other way of looking at the bound object. I need to figure out the Type for the bound object, even if the value is null (this is where my problem is).

I was evaluating the binding by binding to an object and then using the object as a way to get the Type, but I need to know the type even if the value is null

How to tell at runtime if my process is CPU bound or I/O bound
by xSauronx in Programming Languages

I have a program where I send data over TCP link. I am using Asynchronous Reads and writes to both the disk and network. If I put a DeflateStream in the middle (so I compress before I write to the network link and I decompress when I receive the data and write it out to the disk) I am CPU bound on the compressing side. This causes my max transfer rate to be about 300 KB/s. However

How to check if app is cpu-bound or memory-bound?
by deshao in Network & Servers

I've got an application that does few computational CPU work, but mostly memory accesses (allocating objects and moving them around, there's few numeric or arithmetic code).

How can I measure the share of the time that am I spending in memory access latencies (due to cache misses), with the CPU being idle?

I should note that the app is running on a Hyper-V guest; I'm not
