I am trying to connect Xeon Phi coprocessors to an external bridge with a wider than default netmask. My bridge br0 on the host has IP 10.33.1.2 with netmask 255.252.0.0 (the first 14 bits set). When I configure MPSS 3.2, I do this:
I am having problems with the actual mpss 3.2 relase in combination with CentOS 5.3 and the Intel 22.214.171.124.8 OFED stack.
The kernel version is 2.6.32-279-11.1 so I ahd to recompile the kernel modules.
As soon as I start the ofed-mic service, the infniniband connections on the host is not working any more (I tested this with a ibv_rc_pingpong). Communication with the card over scif0 interface is possible, but only with a poor bandwith (73.34 Mbit/sec). dmesg shows follwing supicous messages
Hi i want to gather a some elements from a array whose indices are specified in "index". Here is the code i have written.
float* arrA = (float*)_mm_malloc(sizeof(float)*500,64);
float* arrB = (float*)_mm_malloc(sizeof(float)*500,64);
for(int i=0; i <42; i++)
arrA[i] =(float )i;
arrB[i] = (float)1;
For some time now, my PC has been freezing periodically - about once every 2 days, the screen looks normal, but mouse, keyboard etc. do not respond and I have to hold the power key in to restart.
By process of elimination, the culprit appears to be the Xeon Phi 3120A card - I just took the card out and ran the PC for a month without a freezing incident.
Put it back in and it froze the same day.
I have tried it in both possible expansion slots - froze with both.
i think its about performance of computer.
Have a beeping problem with new ram memory - 4gb.
beeping , and no display.
According to this, my destop board could accept memory stick, but pratically not.
i've just updated my old mpss to the latest 3.2, and found that now ssh requires root password. i'm wondering how to allow non-root users to ssh and scp.
I heard that "GPU can create threads using hardware, one instruction creating one thread".
Does Phi have similar support? For example, when I use OpenMP, can I use some features of Phi to reduce the overhead of creating threads?
Thanks very much.
Hello, I want to generate xeon phi workstation using intel MPI.
Thus, I've already set up xeon phi and run test code using below thread.
However, MPI Offload model & Symmetric model is not working with this error message if I run below MPI task.
I'm using VTUNE to look at the hotspots in my code. I'm down into the vector instructions and confused by a few things. I understand that VTUNE isn't a cycle accurate simulator, but why it is that I see things like the following:
