Yes, $14k makes sense. I thought it's a real bargain:-) Are a couple of the Things nodes still available for MCS projects? or should I make a purchase request for additional Haswell nodes on behalf of MCS folks? (maybe this is a question to Kumar) I'll ask individual to write a project description if they have submitted it yet. The current version of sniper simulator does not scale well. It's barely scale to 10 cores. NUMA does not help. NUMA just adds additional complexity. A higher clock, single socket node may be a better choice, btw. I'll return the node I'm currently using on Fri. I'll be out of town anyway. - kaz On 03/30/2015 11:31 PM, Allen, Benjamin S. wrote:
Thanks for compiling all of the projects.
I misread our recent quote. Thing nodes cost $14,135.45 each (double what I mentioned before). The E5-2699v3 goes for about $4200 per socket, so that cost shouldn't be all that surprising.
It may make more sense to purchase hardware for file system benchmark clients to offload the ALCF Lustre and DDN IME projects from the Thing nodes versus purchasing more E5-2699v3 servers.

Currently two project are listed in JLSE require haswell nodes.
- Energy Savings and Performance Optimizations With Pliable Algorithms on Intel�s E5-2699v3 (Haswell) Nodes (PIs: Adam Hammouda, Andrew Siegel and Pete Beckman)
- Exploring the Potential of Modern Processors (PI: Kazutomo Yoshii)
Beside the above projects, I think Ron Rahaman and other CESAR folks are exploring cluster-on-die.
I have an on-going work with a MIT guy for application energy study.
The members of the COOLR project are interested in. I'd like my student to have an access to the haswell node this summer for low-level OS work.
Aaron Knoll (currently at U. of Utah) is interested in many-core with a big memory configuration. He is visiting ANL this summer.
I guess several people are interested in or may depend on haswell nodes.

Yea lets wait till Haswell-EX (4 & 8 socket Haswell) ships before looking at a 4 socket machine.
We're purchasing two more "Thing" machines to dedicate to the Intel Simulator project at minimum. What other projects do you have in mind?

Thank you for the info!
I think two or three projects depend on haswell nodes, so it would be nice to have additional "Things" nodes, at least two. (one for regular sharing and another one for time-sharing; isolated performance test or OS devel)
If we can add more memory to the node, we can accommodate one more project.
I was thinking to request a 4-way node but E7 SKUs may not be available yet or very expensive, so I'll postpone it.

We can keep the HD installed, however I'd highly suggest you purchase a dedicated node, since LCF will be using these nodes for Lustre and DDN IME testing for the next few months. These projects are high priority.
Cost for one of the "Thing" Haswell-EP nodes is $7,025.225 as of today.

Ben,
Thank you for letting me playing with the node! I'll unplug the node on this Fri.
The machine helped my work a lot! One paper was accepted, which I haven't reported to JLSE yet. I have done a couple of other works, including a 4.0 Linux kernel bug fix.
Are you able to keep the hard drive I installed to the node? I'd like to reboot the node with my disk image later when the machine is not busy. I have a couple of unfinished works related to Haswell.

Hi Kaz,
I need the Haswell-EP node back by next Monday.
Thanks,
