Sept. 12 -- The Numerical Algorithms Group (NAG) announces new numerical functionality added to its numerical library for C and C++ programmers. The new functionality at Mark 23 of the NAG C Library brings the number of routines to 1452, all of which are expertly documented and includes two entirely new chapters plus extensions in the areas of statistics, nonlinear equations, wavelet transforms, ordinary differential equations, interpolation, surface fitting, optimization, matrix operations, linear algebra, large scale linear systems, and special functions.
Software developers writing in the popular C / C++ language that require accurate and reliable numerical functionality are faced with a dilemma. If they have the expertise they could consider writing and testing their own numerical code but this can be extremely time consuming for any nontrivial component. Alternatively they could be persuaded, primarily on initial financial outlay, to utilize freeware but this software is often unsupported and could therefore be considered a more risky option in the longer term. The most cost effective and safe option is to use a trusted numerical function provided by NAG that has been acutely tested and expertly documented; it can be relied upon to do the job.
The inherent flexibility of the mathematical and statistical routines in the NAG C Library enable it to be used across multiple programming languages, environments and operating systems including Excel, Java, Microsoft .NET, Visual Basic and many more.
New NAG C Library mathematical and statistical functionality:
A Senior Quant from a Tier 1 Investment Bank commenting on Mark 23 releases of theNAG C Library said “We embed the NAG C Library in most of the bank's C++ Libraries. Of the new Mark 23 functionality that I have seen obvious finance highlights for us are the inclusion of matrix functions (especially exponential), the additional nearest correlation matrix functions, the skip ahead for Mersenne Twister (as this is pretty non trivial to implement) and the vectorized simple functions in the Statistics and Special Functions chapters. My colleagues will also be very pleased with the additional root finding algorithms and new local and global optimization functions”
More benefits of the NAG C Library:
The NAG C Library is available for 32-bit and 64-bit Microsoft Windows and 64-bit Linux systems; it will also be available for 32-bit Linux and Mac OS X. 30 day trials of the full Library are available on request. For more information visithttp://www.nag.co.uk/numeric/CL/CLdescription.asp.

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.
