For more details refer to this link The following code will give you CPU ID: namespace required System.Management var mbs = new ManagementObjectSearcher(“Select ProcessorId From Win32_processor”); ManagementObjectCollection mbsList = mbs.Get(); string id = “”; foreach (ManagementObject mo in mbsList) { id = mo[“ProcessorId”].ToString(); break; } For Hard disk ID and motherboard id details refer this-link … Read more
With your programs, I get (write) Bandwidth = 6.076 GB/s (read) Bandwidth = 10.916 GB/s on a desktop (Core i7, x86-64, GCC 4.9, GNU libc 2.19) machine with six 2GB DIMMs. (I don’t have any more detail than that to hand, sorry.) However, this program reports write bandwidth of 12.209 GB/s: #include <assert.h> #include <stdint.h> … Read more
All calculations take place in the registers. When you’re adding (or subtracting, or whatever) variables together in your code, they get loaded from memory into the registers (if they’re not already there, but while you can declare an infinite number of variables, the number of registers is limited). So, having larger registers allows you to … Read more
That’s mostly a matter of tradition. It is not even always true. For example, floating-point units in processors (even contemporary ones) have 80-bits registers. And there’s nothing that would force us to have 8-bit bytes instead of 13-bit bytes. Sometimes this has mathematical reasoning. For example, if you decide to have an N bits byte … Read more
I investigated the same question a while back. After chatting to people who have worked on FPGAs, this is what I get: FPGAs are great for realtime systems, where even 1ms of delay might be too long. This does not apply in your case; FPGAs can be very fast, espeically for well-defined digital signal processing … Read more
C# itself doesn’t define the endianness. Whenever you convert to bytes, however, you’re making a choice. The BitConverter class has an IsLittleEndian field to tell you how it will behave, but it doesn’t give the choice. The same goes for BinaryReader/BinaryWriter. My MiscUtil library has an EndianBitConverter class which allows you to define the endianness; … Read more
For Linux, you might look into picking up the O’Reilly Linux Device Drivers book or reading PDFs online. In my opinion, it is one of the better texts around on the subject. The Linux Kernel Module Programming Guide is another good resource. You may also want to pick up a book specifically on the Linux … Read more
A “hardware thread” is a physical CPU or core. So, a 4 core CPU can genuinely support 4 hardware threads at once – the CPU really is doing 4 things at the same time. One hardware thread can run many software threads. In modern operating systems, this is often done by time-slicing – each thread … Read more
The answer revolves around the purpose of threads, which is parallelism: to run several separate lines of execution at once. In an ‘ideal’ system, you would have one thread executing per core: no interruption. In reality this isn’t the case. Even if you have four cores and four working threads, your process and it threads … Read more
