Yeah i saw that some websites charge money for that. I saw the Dolphin website wants $5000 for a developer license or something vague. I call that 'download rights for the SDK'. Sounds weird to me. As for the MT26418 that's $562, that's factors too much for a low budget cluster that's low latency. Another website i checked out was an Indian website: plx technologies. Seems in India. However didn't allow me to register. For bandiwdth you don't need to check them out, as in some webvideo i saw them speak about 600MB/s as if it was a lot, which is of course a joke even to old 4x infiniband, which gets handsdown 800MB/s. But for latency might not be bad idea. Yet didn't allow me to register that plxtechnologies, which is weird. > Prentice > > _______________________________________________ > Beowulf mailing list, [email protected] sponsored by Penguin > Computing > To change your subscription (digest mode or unsubscribe) visit > http://www.beowulf.org/mailman/listinfo/beowulf _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
