| 10 | long_description A high-performance generic component library that |
|---|
| 11 | provides comprehensive linear algebra functionality for a wide \ |
|---|
| 12 | variety of matrix formats. As with the Standard Template Library \ |
|---|
| 13 | (STL), MTL uses a five-fold approach, consisting of generic \ |
|---|
| 14 | functions, containers, iterators, adaptors, and function objects, \ |
|---|
| 15 | all developed specifically for high performance numerical linear \ |
|---|
| 16 | algebra. Within this framework, MTL provides generic algorithms \ |
|---|
| 17 | corresponding to the mathematical operations that define linear \ |
|---|
| 18 | algebra. Similarly, the containers, adaptors, and iterators are \ |
|---|
| 19 | used to represent and to manipulate concrete linear algebra \ |
|---|
| 20 | objects such as matrices and vectors. To many scientific computing \ |
|---|
| 21 | users, however, the advantages of an elegant programming interface \ |
|---|
| 22 | are secondary to issues of performance. Generic programming is a \ |
|---|
| 23 | powerful tool in this regard as well - performance tuning can \ |
|---|
| 24 | itself be described in a generic fashion. These performance tuning \ |
|---|
| 25 | abstractions are realized in a generic low-level library - the \ |
|---|
| 26 | Basic Linear Algebra Instruction Set (BLAIS). Experimental results \ |
|---|
| 27 | show that MTL with the BLAIS achieves performance that is as good \ |
|---|
| 28 | as, or better than, vendor-tuned libraries. Thus, MTL demonstrates \ |
|---|
| 29 | that the proper abstractions can be used to achieve high levels of \ |
|---|
| 30 | performance, contrary to conventional wisdom. In addition, MTL \ |
|---|
| 31 | requires orders of magnitude fewer lines of code for its \ |
|---|
| 32 | implementation, with the concomitant savings in development and \ |
|---|
| 33 | maintenance effort. |
