Micctl not seeing card

Brian_Andrus — Tue, 20 Aug 2013 19:51:15 GMT

All,

Having trouble getting the mic drivers working.

Running CentOS 6.4 with the 2.6.32-358.6.2.el6.x86_64 kernel (this is because we use Lustre as well).

I am able to compile and install the kernel drivers and I can load the mic module:

[root@compute-8-35 ~]# lsmod|grep mic
mic 581887 0

But:

[root@compute-8-35 ~]# /opt/intel/mic/bin/micinfo

I see a ton of stuff for the two cards under 'lspci' is there anything in particular to be looking for there?

Hi Brian, I was looking at older posts and saw that no one replied to you ...

A common problem is not having "large BAR" support enabled in the systems BIOS. You usually see this as an option under "advanced settings" related to the PCI bus. It's often referred to as "Above 4G decoding" Look for that and make sure it's enabled.

If you have that enabled and the cards are still not seen then look near the top of the lspci -v output for one of your cards ... if you see something like

Memory at <ignored> (64-bit, prefetchable)

then your motherboard is probably not going to support Phi.

Best wishes -Don

Don,

Don,

Thanks. It turned out I needed to flash the MIC cards and then they showed up as expected.
