Here is a problem with Arenas and full file systems: I am attempting to run my grand opus program on a number of different sgi systems around here (NYU). All of the public machines have almost completely full disks. All of the public machines also have > 32 MB memory which is generally not always in use. Now I load up my arenas with about 14 MB of pixels to be processed by my collection of programs. While the memory is available, the disk space is NOT. So my Arena setup and load program is failing because the Arenas take up too much disk space. The system can't run for lack of disk space when there is lots of memory. I get the pixels from my nfs mounted pixel server disk, so they (the pixels) don't take up space on the host machine. This seems odd since the Arena file is only an image of the shared memory mmap'ed to disk. It should only be flushed to real disk when the Arena is closed. Is there any way around this problem ? Consider that most machines run with full disk file systems. It is harder to ask for 14 MB disk scratch space than to just keep 14 MB of files just to reserve space for the Arena. | karron@nyu.edu (e-mail alias ) Dan Karron, Research Associate | | Phone: 212 263 5210 Fax: 212 263 7190 New York University Medical Center | | 560 First Avenue Digital Pager <1> (212) 397 9330 | | New York, New York 10016 <2> 10896 <3> <your-number-here> |
