The jobs you submitted were not run because of some trouble with the server. I have just resubmitted them to NEOS, the results will be available from the 'view job status/results' page. http://neos.mcs.anl.gov/neos/admin.html Your new jobs are: jobNumber = 1826443 password = sNxVyLcG (previously 1825462) jobNumber = 1826444 password = yVBxaYzd (previously 1825463) Sorry for the trouble, let us know if you have any more questions, Jason Sarich Argonne National Laboratory On Fri, 13 Mar 2009, Ramadan, Mohamed wrote: > Dears, > > thanks for your amazing site. > > actually i faced an unknown problem. i sent some jobs > > as > 1825462 > CsVqOibu > > (and) > > 1825463 > RkiNMyuY > > after it was finished, and i ask the server for results, the next messages was appeared: > > Job 1825462 has finished. > Results for Job #1825462 are no longer available > > Job 1825463 has finished. > Results for Job #1825463 are no longer available > > > > Thanks and best regards > > > > > Mohamed Ramadan, MSC > Researcher / Analyst > Population Council WANA Regional Office (59 Misr Agricultural Road, Maadi, Cairo, Egypt) > Mob.: 01 22 36 76 26 Tel.: (002) 02 25255965/7/8 ext. 245 >
