The process of residue division has certain interesting properties and quite possibly has applications in respect to special problems. Unfortunately, the residue division process is not a substitute for normal division. It appears that the only way in which division can be effected in the residue code is by the utilization of techniques similar to those employed for division in a consistently w...

For six years our computer science program had no dedicated computing laboratories and limited influence on the software that could be installed on university wide workstations. In the fall of 2009 we remedied this situation by teaching a course where computer science students built their own labs. We describe the design process including physical plant, hardware and software configurations of ...

A larger, faster memory system with error correction and error logging, a faster central processor, an expanded in struction set, and a more efficient operating system are the major technological advances. Benchmark studies rate the new HP 3000 Series II Computer Systems at two to four times the throughput of earlier versions. LIKE EARLIER VERSIONS OF THE HP 3000 Com puter System,1 the new HP 3...

I will discuss the application of redundancy-sorting techniques to the resolution of semantic problems. I must leave it to you to decide whether or not these techniques actually deal with semantic problems. I believe they do, even though this paper describes a manual of operation for a computer program. I should perhaps explain that the term "redundancy sorting" refers to a battery of data-proc...

N -body simulation is a time consuming task in which force calculation part is most dominant part. The simplest and most accurate algorithm for force calculation is direct summation which has time complexity O(N). It is not practically suitable for large-scale simulations on most general-purpose computers. To cut down cost of force calculation one applies fast algorithms or performs force calcu...

Molecular dynamics (MD) simulation is one of the most exact and powerful method to study protein biophysics and biochemistry. However, its use is still limited by its high requirement of computational power. To solve this problem, several special-purpose computers have been built. The most successful machines are GRAPE family [1], GRAPE-2A, MD-GRAPE, and MDM. Especially, MDM [2] with 78 teraflo...

We are developing the MDGRAPE-4, a special-purpose computer system for molecular dynamics (MD) simulations. MDGRAPE-4 is designed to achieve strong scalability for protein MD simulations through the integration of general-purpose cores, dedicated pipelines, memory banks and network interfaces (NIFs) to create a system on chip (SoC). Each SoC has 64 dedicated pipelines that are used for non-bond...

Slit-scan flow cytometry provides a method to analyze large numbers of metaphase chromosomes in a relatively short time due to morphological features. The high detection rate requires fast computing for on-line analysis. Up to now, this has been achieved using special-purpose computers, parallel systems or other complex hardware. Here, we describe an algorithm that can be implemented on a gener...
