Frequenzweiche Berechnen Software Programs

The point of this page, such that it is, is to provide some idea of how various pi programs perform on Linux. Basically, I shamelessly copied the format that used, and added a few more measurements. I really wouldn't have done this at all except that Stuart does all his testing in Windows, and he uses a P-IV. As I don't like Windows, and I think the P-IV doesn't show a lot of these programs in the proper light, I created this.

Program Rca Universal Guide Plus Gemstar Remote Download Free Software Programs Online. Frequenzweiche Berechnen Software. Please, if you see other fast pi programs out there, send them in, and I'll add them to the table. Note: I would appreciate if total runtime of the programs.

It is still very much under construction however. All the programs on this chart run on x86/Linux, either natively, or through Windows emulation. The test was performed on an HP Visualize X Class with dual 733MHZ P-III processors and 1024MB RAM. Programs which were compiled were built with Intel C/C++ 5.01 with optimization set to the default. Relative speed is number of times as fast as SuperPi. News 3/17/02 Beautified the page and added Jorg Arndt's hfloat based pi calculator (I called it hfloatpi). 3/12/02 Another new program is out, Alan Pittman's Chudnovsky based program.

It's quite fast, and is even faster than ahppi2. 2/22/02 A new program, which I'm calling gmp-chudnovsky, by Hanhong Xue, has appeared. It looks to be a good 30% faster than gmp-ramanujan, which is quite an improvement.

Windows binaries should be out in a day or too. Quick note: Windows binaries of gmp-pi all crash when you try to print out more than ~140,000 digits (they'll calculate fine, but setting print output to 1 causes the crash), due to a bug in the dll. I've rebuilt the dll, but to no avail. I'm going to ask the GMP guys if they know what's wrong. A special thanks to, who provided both the motivation and the model for the page.

Also thanks very much to the authors of the programs below for bringing them to us. I particularly want to thank:, (whose name I've been misspelling for the last year, it's Takuy a, not Takuy o), and, who not only created great programs, but also gave the sources out for everyone to compile, copy or try out. Thanks again guys! Program name Author Performance Relative Speed Max # digits Notes Download QuickPi 2.0 Steve Pagliarulo 13.00 14.31 256m QuickPi 2.0 is a relative newcomer, but for less than 8m digits, it's faster than anything else. It is available for Windows, and no source is provided.

Runs fine under in Linux. Binary: Dominique Delande 15.78 11.79 512m Schnell_Pi popped up last August as a bit of a surprise. It is the only Linux-only pi program, and no source is available. For more than 4m digits, it is the fastest program I've yet seen. Note that I do not approve of closed source Linux programs any more than closed source Windows ones.

I hope that the source will be made available eventually. Binary: Xavier Gourdon 16.00 0m PiFast was the first program available to beat pi_css5 convcincingly. It currently also has the record for the most digits calculated: some 12billion (12*10^12)! It is available for Windows only, but works under Wine. Binary: gmp-chudnovsky Hanhong Xue 20.29 9.17 32m gmp-chudnovsky is an open source pi program based upon the arithmetic package. Although it is not good for larger numbers of digits, it does demonstrate what can be done with GMP.

Source: binary: or gmp-ramanujan Hanhong Xue 28.83 6.57 4m gmp-ramanujan is the precursor to gmp-chudnovsky. It fits right between gmp-gauss and gmp-chudnovsky in terms of speed source: binary: or Mikko Tommila 34.42 5.40 226m This program was intended as a test of the apfloat numerics package. However it is also an excellent open source pi program, and the only one I know of which is multithreaded, and so used both processors on the test machine. Source: binary: or Takuya Ooura 36.52 5.09 67m pi_css5 is my favorite program for calculating pi. It's fast, small and very portable, so it is the centerpiece of my computer benchmark tests. It was not intended for vast numbers of digits, but still scales pretty well. Source: binary: or Carey Bloodworth 41.28 4.51 8m (see below) pi agm was the first pi program I started playing with.

While it has gotten larger and more complicated over the years, it is an excellent example of organization and programming. This version uses the fft-hartley for optimal speed, although it can use a large number of different ffts/ntts. Source: chud14 Alan Pittman 55.39 3.36 32m chud14 is Alan Pittman's newest pi program based on the fft package, and using the Chudnovsky formula. Source: Mikko Tommila 60.11 3.09 226m This is the single processor version of the above program.

While it is slower, it gives an interesting insight into how much benefit is gained from 2 processors over 1. Source: Carey Bloodworth 66.03 2.82 1024m This version of pi agm was designed for longer runs, and was the first pi program to calculate 1billion digits on a PC. Source: gmp-gauss Hanhong Xue 68.75 2.71 4m gmp-gauss is the counterpart of gmp-ramanujan using the gauss agm formula. Using GMP 4.0, I get about 25% better results than I did with GMP 3.1. Source: binary: or ahppi2 Alan Pittman 76.97 2.42 4m ahppi2 is Alan Pittman's pi program based on the fft package.

It a much faster and improved version of ahppi source: Sebastian Wedeniwski 91.80 2.03 8m piologie is a Windows program to calculate pi, e, and lots more besides. Binary: Jorg Arndt 95.70 1.94 8m hfloatpi is a rather old, and somewhat complex pi program, although it can calculate much more than pi. While it does have source, I couldn't get it to build. Source: binary: Yasumasa Kanada 186 1.00 32m SuperPi is an old Windows pi program, but it was the first capable of calculating 32 million digits, and was written by the same guy who calculating 68billion digits at the University of Tokyo in 1998 (not on a PC though) binary: or Please, if you see other fast pi programs out there, send them in, and I'll add them to the table. Note: I would appreciate if total runtime of the programs sent is less than SuperPi, as I'd like that to be the line between fast and not so fast programs. Here is more complete table of pi timings made from the above programs. I organized them in order of speed, as best I could.

Unfortunately, a number of them do not go up to 64meg of digits, so I my ordering scheme may not be accurate. I'm sure this would all look much better in graphic form, but 'til I find a good graphing program, that'll have to wait. Runs were performed on the same system as above. Number of digits is in megabytes (n*1048576) and data is number of seconds run took to complete. Tutorial Belajar Bahasa Arab Pdf To Jpg more.

Welcome to the home page of ARTA software - a collection of programs for audio measurements and analysis in acoustical and communication systems. ARTA software uses standard and professional PC sound cards and interfaces for audio signal acquisition and generation. The ARTA software consists of following programs: ARTA - program for the impulse response measurement and for real-time spectrum analysis and frequency response measurements. STEPS - program for frequency response measurements with stepped-sine excitation. Simultaneously with a frequency response measurement the program estimates levels of 2nd, 3rd, 4th, 5th and higher order harmonic distortions. LIMP - program for the loudspeaker impedance measurement and loudspeaker parameters estimation.

The ARTA program has functions of following measurement systems: Signal generator of following signals: white noise, pink noise, periodic white noise, periodic pink noise, speech signal, sine, two sine, multitone, triangle, square. Impulse response measurement system Single and Dual channel Fourier analyzer Spectrum, octave band and THD analyzer Triggered storage scope Two-channel voltage level meter and third octave analyzer With calibrated microphone, ARTA can be used as a virtual IEC class 1 SPL meter with a real time modes: Integrating SPL meter with 24 hours data logging, Octave SPL meter with noise rating (NR, NC, PNC, RC, NCB), Third octave SPL meter with report of specific loudness, loudness in sones and loudness level in phones.
