That is a good thing, isn't it? We do have some update in performance, such as, the latest default windows version is on 64-bit (on Linux it was 64-bit from 2 years ago), the parallel computing gets more stable now, etc.<br /><br />In short, you may still prepare the hardware according to your budget.<br /><br />Cheers,<br /><br />QinghuaQinghua Ye2015-10-09T08:15:02ZRE: Optimal machine build for D3D?Adri Mouritshttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806675&messageId=2330302013-01-15T14:51:57Z2013-01-15T14:51:57ZHi Shawn,<br /><br />I did not do any detailed performance tests, but looking at some tests in another project, i7 seems to be faster than Xeon. Graphics is not a bottle neck.<br /><br />Regards,<br /><br />AdriAdri Mourits2013-01-15T14:51:57ZRE: Optimal machine build for D3D?Shawn Harrisonhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806675&messageId=2314812013-01-10T20:36:44Z2013-01-10T20:36:44ZThank you for the tips Adri. I will keep that in mind. <br /><br />Any other tips? E.g. Intel i7 vs Xeon? Minimum graphics card, e.g. Is NVIDIA GeForce GT640 enough, or should I shoot more for NVIDIA Quadro 2000 bottom end?Shawn Harrison2013-01-10T20:36:44ZRE: Optimal machine build for D3D?Adri Mouritshttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806675&messageId=2307552013-01-09T14:12:04Z2013-01-09T14:11:14ZHi Shawn,<br /><br />Some tips:<br /><br />Hardware:<br />Use Intel processors (in combination with the Intel compiler). <br />A lot of cores is only interesting when you can run parallel. If you mainly do combined FLOW - WAVE calculations, SWAN will use all cores but FLOW won't. Using DomainDecomposition will enable FLOW to use more than one core. Of course you can always do separate calculations at the same time.<br /><br />Software:<br />Linux is faster than Windows.<br />Use the Intel compiler (in combination with Intel processors).<br /><br />Regards,<br /><br />AdriAdri Mourits2013-01-09T14:11:14ZOptimal machine build for D3D?Shawn Harrisonhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806675&messageId=2304092013-01-08T18:30:27Z2013-01-08T18:30:27ZHi All, <br /><br />I'm thinking to buy a new computer for the primary purpose of running D3D models. Of course, I enjoy heavy matlab computing as well.. and want graphics capabilities to make fast, intricate plots (and dual monitors).<br /><br />I'm curious if any one has suggestions about recent builds or hardware specifications particularly well-suited for running fast, stable D3D simulations. <br />Mainly, I use D3D for morphological modeling (FLOW-WAVE coupling with sediment updating). <br /><br />Thanks in advance for your advice,<br />ShawnShawn Harrison2013-01-08T18:30:27Z
