Keith,<br><br> Memory is per process so if you are 128 cores then you will need 128*7000 mW of memory. If your job needs more memory then you can reduce number of cores that you are requesting.<br><br><div class="gmail_quote">

<div>Hi all,</div><div><br></div><div>I'm having a lot of problem completing jobs on blacklight, which is a machine at the Pittsburgh Supercomputing Center.</div><div><br></div><div>I'm trying to run a job requesting 7000,m. That is, 7000 megawords, which I thought would be 54 gigabytes. My job winds up dying (when run on 128 cores = 8 blades @ 128 GIGS per blade, which means I have access to a terabyte of memory. Yet, my job is killed with the following error message:</div>
<div><br></div>Creating: host=bl0.psc.teragrid.o=>> PBS: job killed: cpuset memory_pressure 139111 reached/exceeded limit 1 (numa memused is 1073599536 kb)<div><br></div><div>Is this behavior understood? Why would my job possibly be using that much memory? I've been in contact with PSC support, but they believe this is a Molpro issue.</div>
