To all experience Myrinet user in beowulf cluster,
In Myrinet site, it is recorded that Myrinet adapter plugged in 32-bit
and 64-bit running 33MHz or 66MHz varies in DMA transfer rates, thus
affecting the data-rate performance.
How is the data-rate performance affect the overall performance? I
just got 32-bit PCI running 33MHz. Is there any significant performance
difference after I replaced the current motherboard that is equipped with
64-bit, 66MHz PCI bus?
Any opinion is welcome.
