Did you check that the PCIe slot you are using is x8 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bart Van Assche Sent: Thursday, January 17, 2008 6:06 PM To: Openib-General Subject: [ofa-general] Performance of MT25204 versus MT25208
Hello, Via ib_rdma_bw and ib_rdma_lat I obtained the following performance data: * peak bandwith 674 MB/s / latency 3.07 microseconds between two uniprocessor systems with MT25204 HCA's. * peak bandwith 935 MB/s / latency 3.36 microseconds between two dual processor systems with MT25208 HCA's. I'm wondering now whether the performance differences are due to the HCA's or due to the motherboard ? Software: 2.6.22.9 Linux kernel (64-bit x86_64) + OFED 1.2.5.4 userspace components.
