Hi Ben, Sorry for the late reply. My ANL user name is: hlu. The account I requested at JLSE has the user name: huiweilu. My latest progress is that I am waiting for the approve from the project sponsor Rajeev.

Thanks Ken, Looks like I haven't request a new account yet. I have send the request and let's wait how it will proceed.

Did you click on "Request or Remove Resource Access" under Account Information? It is towards the bottom of the page after you login to accounts.jlse.anl.gov. The "JLSE General Resources" checkbox grants you SSH access. Ken On 04/28/2015 12:46 PM, Huiwei Lu wrote: > Hi, > > I am trying to apply for a JLSE account on the website.

I forgot to mention that my ANL user name is: hlu. One more thing, I can login with the "Request New Account" link but I can not login in the "Account Management" link. It tells me "Login Error: Unable to find account hlu".

Hi, I am trying to apply for a JLSE account on the website. I can login in with my ANL credential. But after login, I didn't see any resource to apply. Another problem is I can not login to login.jlse.anl.gov. I checked that my SSH public key in "Credentials" but it keeps asking for a password. I used ANL password but it was not correct. Could you tell me what am I missing? Thanks, -- Huiwei Lu Postdoc Appointee Mathematics and Computer Science Division Argonne National Laboratory http://www.mcs.anl.gov/~huiweilu/

Re: [JLSE-Admins] Hardware threading on thing nodes
by Paul Romano 27 Apr '15

Hi Ben, One aspect of the study I'm performing is to look at any potential differences between the situation you just described, i.e. only using as many threads as there are physical cores with HT enabled, and actually disabling HT altogether, so unfortunately binding to the first hardware thread won't suffice. Once I have everything scripted and ready to go, it shouldn't take more than a day or two to perform the actual runs.

Hi Paul, Will running your application with taskset or numactl suffice, eg: taskset -c 0-35 cmd or numactl -C 0-35 cmd? Thus pinning the application to the first hardware thread on each core. If not how long do you think you'll need a machine with HT disabled?

Hi, I'm currently doing some studies on the impact of hardware threading on code performance for nuclear reactor neutronic calculations. I was wondering if it might be possible to have one of the thing nodes configured with hardware threading disabled for the sake of running comparisons. Thanks, Paul
