Eric, I use VMWare so that I can test multiple OS against ideas I have. For example, I am considering porting my stuff to Linux using Mono, and I run Ubuntu under VMWare. As far as using VMs for realtime trading, that would not be my cup of tea as my stuff is sensitive in the sub millisecond range. But it may work for others. nitro
Newly announced and a strong competitor, and much cheaper: http://www.nvidia.com/object/geforce_gtx_280.html AMD is coming out with a "Fusion" version which may be the way to go, as in theory the latency between GPU and CPU should be greatly reduced compared to GPus on the PCIe bus. If you have not read this whole thread, my interest in these GPUs is not for gaming, but for their massively parallel computation capabilities. Very exciting. nitro
nitro - How is the linux/mono project coming along? I have been looking at that but I am not a strong enough developer to add in that additional complexity. Have you been using the Amazon EC2 for anything? if so how haave your experiences been so far? Regards, Eric
I believe the GTX 280 is a renamed 9800? In any case, this is the card I have been waiting for because it supports native double-precision: http://news.cnet.com/8301-13512_3-9969234-23.html nitro
That's a sharp question. There is no real reason, other than I am more experienced with GPUs. However, that may change soon. What I want is an FPGA/GPU that has a built in NIC. That way I don't have to do communication between the CPU and GPU/FPGA through the bus. All the computation, the whole program, could live in the GPU/FPGA then and real-time market data would stream right into the GPU/FPGA. I just don't know much about them... nitro
BTW, get your wallet out: http://www.amazon.com/gp/feature.html/?ie=UTF8&docId=1000241401 http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Description=GTX+280 http://www.microcenter.com/single_product_results.phtml?product_id=0291632 Cheap though by comparison to other double-precision cards. nitro
