Pengfei, It looks like you checked the 'put in priority queue' box on the web form, this is designed for quick jobs that can run in less than five minutes. If you don't check the box, then NEOS will allow it to run longer -- but it might take longer to start.

Graeme, NEOS submissions do not run on supercomputers, they mostly run on off-the-shelf workstations. It shouldn't be too surprising that your 12-hr job wouldn't finish on our computers in time.

Ramon, Unfortunately, the machine that your BARON job was running on crashed this morning, you will have to resubmit the information.

Hi I´m trying out the server for the first time, using some test GAMS code. Yesterday I submitted a run and saved the ID and password. Today I was able to browse the results using those. I did not receive an email message, however, although I am quite sure. I entered my address. A short while I go I received the message cown below, informing that results were available for another job, number 1856840. I saw the message 10 minutes later, and I went to retrieve the results with the userid and password for it. This time I get this message telling me the results are no longer available: ************************************************************* NEOS Server Version 5.0 Disclaimer: This information is provided without any express or implied warranty.

Hi I am currently trying to solve a large mathematical program involving Augmented Lagrangian decomposition. The problem solves on my computer in 12 hours. However, it cannot solve on any of the nonlinear solvers I have tried (KNITRO, CONOPT, MINOS, SNOPT) on NEOS, which surprises me, as I thought the supercomputer would be much faster. I have attached the GAMS code and are wondering if you may be able to inform me why you think it cannot solve on the NEOS system under the time limit? Regards Graeme

Hi, I tried to use the XPressMP Linear Programming Mosel Solver on your NEOS server website, but the problem is that the output it gave me is the following: NEOS Server Version 5.0 Job# : 1855216 Password : VLGaHqsP Solver : lp:XpressMP:MOSEL Start : 2009-04-27 15:26:06 End : 2009-04-27 15:26:07 Host : blatz.ie.lehigh.edu Disclaimer: This information is provided without any express or implied warranty.

Is there any way that you update your license information on the online XPressMP Mosel Solver you have on the NEOS server so that I can submit a Mosel model to be solved?
