  1. Implementing Better Task Scheduling for Servers?

    Ask · Unix · · posted by Cliff · from the complex-cron-jobs dept. · 30 comments
    trifakir asks: "We are running some quite expensive SunFire servers with Solaris 8. In the 'crontabs' of these hosts we have scheduled maybe some hundred odd jobs, which are constrained by multiple factors: dependencies on other jobs, time constrains, CPU and memory usage, network bandwidth, and so on. Obviously this imposes a CSP. On the other hand the number of these jobs, each one of them can take from minutes to hours is growing and we are now experiencing performance problems given the limited resources we have. Of course we have opened the bag-of-tricks with our best *ad-hoc* solutions, using mostly Open Source software, to turn our system into an event-based and less dependent on the scheduling expertise of the admins. At certain point we were considering using AutoSys and I was looking for a grid-like scheduler like OpenPBS, both of which were discarded for various reasons. I am curious, how you guys, would solve this problem, which seems very trivial for many environments. Both advice about theory (scheduling) and practice will help us and any other readers who may be tackling this difficult problem."

    Troy Baer writes: "SGI and the Ohio Supercomputer Center (OSC) have announced the installation of the first cluster using Itanium processors. The system consists of 73 SGI 750 nodes, each with two Itanium 733MHz procs and 4GB of memory, connected by Myrinet 2000 and Ethernet. Software includes Linux/ia64, SGI's ia64 compiler suite, MPICH/ch_gm, OpenPBS, and Maui Scheduler."
