NESL

NeSL integrates parallel ef="module.php?name=Lexikon&file=search&eid=1&query=algorithms">algorithms, {functional languages} and implementation techniques from the system' s community. Nested ef="module.php?name=Lexikon&file=search&eid=1&query=data parallelism">data parallelism offers concise code that is easy to understand and debug and suits irregular data structures such as ef="module.php?name=Lexikon&file=search&eid=1&query=trees">trees, ef="module.php?name=Lexikon&file=search&eid=1&query=graphs">graphs or ef="module.php?name=Lexikon&file=search&eid=1&query=sparse matrices">sparse matrices. NeSL' s language based performance model is a formal way to calculate the "work" and "depth" of a program. These measures can be related to running time on a ef="module.php?name=Lexikon&file=search&eid=1&query=parallel computer">parallel computer. NeSL was designed to make parallel programming easy and portable. Algorithms are typically more concise in NeSL than in most other parallel programming languages and the code resembles high-level ef="module.php?name=Lexikon&file=search&eid=1&query=pseudocode">pseudocode. This places more responsibility on the ef="module.php?name=Lexikon&file=search&eid=1&query=compiler">compiler and ef="module.php?name=Lexikon&file=search&eid=1&query=run-time system">run-time system for achieving good efficiency.
