Also I have recently found this paper http://www.mathematik.uni-dortmund.de/lsiii/static/showpdffile_GoeddekeStrzodkaTurek2006.pdf.
Some citations: "The double-single emulation on the GPU is not always sufficient, as the double format has a clearly larger mantissa and exponent range than the emulated format: 52/46 = 1.13, 211/28 = 8, and three term emulations become truly expensive. Therefore, we perform the high precision corrections on the CPU rather than emulating them on the GPU ... Instead, the GPU accelerates the more regular, most demanding parts of the algorithms, and leaves the subsequent processing of the results to the well tested, higher abstraction code on the CPU" Jernej --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-forum URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
