I've just parallelized a fortran routine that simulates individuals behavior and I've had some problems when generating random numbers with Vector Statistical Library (a library from the Math Kernel Library). The structure of the program is the following...

So you must allocate....
Eventually, two threads will try to update the same piece of memory at the same time and the result will be non-predictable .
The random number code is either using a global variable internally or all threads use the same generator .

Read all....
However, you can implement one (or surely find code" and is related to quicksort .
No, there is no such function in the standard C library.
No, there is no median function in the standard C library.
In the middle

We currently have a high-performance scientific application written in C++ that makes use of Intel Math Kernel Library .
We are considering writing a benchmark application written in Java and .NET/C# to compare the performance difference. To do that, ...

Lol..why didnt I think of this before?
Just use Intel MKL Math library in Java and .NETI can help with C#:
Here is another SO question that discusses various C# math libraries
And you.
It helps.

There is a Java library by the name of Uncommon Maths that claims to provide better random number generators than Sun and (potentially) even BouncyCastle. How one can determine whether their library can be trusted? I trust Sun and BouncyCastle because...

You can always be a scientist and re-run those tests for yourself... .
That's as reliable as I know.
A basic check of a random number generator can be done using a chi-square test
Uncommon Maths claims to pass the Diehard tests .
Write your own tests.

Instead of just Group.
Compilers and Intel Math Kernel Library (MKL) usually provide the best performance.

If I put stdlib.h or stdio.h, I don't have to link those but I have to link when I compile:
gcc test.c -o test -lm
What is the reason for that? Why do I have to explicitly link the math library but not the other libraries?
Any links explaining why would...

The math function of programs have no floating-point math and they probably took every library that wasn't commonly used in the math ....
Stdio is part of the standard C library which, by default, gcc will link against.

I'm looking for a Java library that is geared towards network math and already tested. Nothing particularly fancy, just something to hold ips and subnets, and do things like print a subnet mask or calculate whether an IP is within a given subnet.

But GSL does have numerical integration capabilities ...is there some other reason this library doesn't meet your needs?
For symbolic math, Mathematica is a popular choice.
