Tuning Up Knights Landing For Gene Sequencing
The Smith-Waterman algorithm has become a linchpin in the rapidly expanding world of bioinformatics, the go-to computational model for DNA sequencing and local sequence alignments. With the growth in recent years in genome research, there has been a sharp increase in the amount of data around genes and proteins that needs to be collected and analyzed, and the 36-year-old Smith-Waterman algorithm is a primary way of sequencing the data.
The key to the algorithm is that rather than examining an entire DNA or protein sequence, Smith-Waterman uses a technique called dynamic programming in which the algorithm looks at segments of …

Assert() in the hands of bad coders
Using assert() creates better code, as programmers double-check assumptions. But only if used correctly. Unfortunately, bad programmers tend to use them badly, making code worse than if no asserts were used at all. They are a nuanced concept that most programmers don't really understand.We saw this recently with the crash of "Bitcoin Unlimited", a version of Bitcoin that allows more transactions. They used an assert() to check the validity of input, and when they received bad input, most of the nodes in the network crashed.
The Bitcoin code is full of bad uses of assert. The following examples are all from the file main.cpp.
Example #1: this line of code:
- if (nPos >= coins->vout.size() || coins->vout[nPos].IsNull())
- assert(false);
This use of assert is silly. The code should look like this:
- assert(nPos < coins->vout.size());
- assert(!coins->vout[nPos].IsNull());
This is the least of their problems. It understandable that Continue reading
Applied Networking Research Workshop – Paper Submission Deadline: 3 April
We’re excited to share news of the second Applied Networking Research Workshop (ANRW2017), which will take place in Prague, Czech Republic, on July 15. This one-day workshop will be co-sponsored by the Association for Computing Machinery (ACM), the Internet Society and the Internet Research Task Force (IRTF). The Call for Papers is open now, with a deadline of 3 April.
Fast Convergence and the Fast Reroute – Definitions/Design Considerations in IP and MPLS
Fast Convergence and the Fast Reroute Network reliability is an important design aspect for deployability of time and loss sensitive applications. When a link, node or SRLG failure occurs in a routed network, there is inevitably a period of disruption to the delivery of traffic until the network reconverges on the new topology. Fast reaction is essential […]
