Profiling with HPC Toolkit

" Ive started working with the HPC Toolkit , especially the part where it can use PAPI to read hardware counters and display the result in a nice GUI. Installation Installation is a little bit of a pain, but it is simplified somewhat, as all external dependencies are available in a unique repository, except for PAPI that ... View More

GSoC Week 6/7

" In the week 6 and 7, I coded BayesianGaussianMixture for the full covariance type.Now it can run smoothly on synthetic data and old-faithful data. Take a peek on the demo. from sklearn.mixture.bayesianmixture import BayesianGaussianMixture as BGMbgm = BGM(n_init=1, n_iter=100, n_components=7, verbose=2, init_params='rand... View More

A response to "The myths of bioinformatics software"

" This is a response to (parts of) Dr. Lior Pachter's post, 'The mythsof bioinformatics software' . (You can also see my post on bioinformatics software licensing for at least some of the background arguments.) I agree with a lot of what Lior says: most bioinformatics software isnot very good quality (#1), most... View More

Audio Toolkit: Zero Latency Efficient Convolution

" Convolution is an algorithm that is often used for reverberations. If the equation is easy to understand and to implement, the implementation is costly. The other way of doing it is to use Fast Fourier Transform (FFT), but the direct/crude implementation requires latency. If it is possible to optimize the basic convolution code... View More

When the last digits of powers don’t change

" If you raise any integer to the fifth power, its last digit doesnt change. For example, 2 5 = 32. Its easy to prove this assertion by brute force. Since the last digit of b n only depends on the last digit of b , its enough to verify that the statement above holds for 0, 1, 2, , 9. Although thats a valid proof,... View More
