Murakami) Newsgroups: comp.unix.bsd Subject: [386BSD] Huge virtual space I need badly. Message-ID: <3730@tansei1.tansei.cc.u-tokyo.ac.jp> Date: 16 Dec 92 19:19:44 GMT Sender: news@tansei.cc.u-tokyo.ac.jp Organization: Hokkaido Univ. However I am subject to tansei for JUNET. Lines: 31 I need the huge virtual space for 386BSD. I found that the current limitation is as little as 32MB. I would like to use as large as 1GB of virtual memory for one process or program to do the large FEM computations. ( I allocated 2GB of HDD for that. Don't tell me that I should not do the pagings. The algorithm is quite efficient to suppress the paging to minimal. ) I tried to change the parameters in the header files to reconfigure the kernel. However, it seems my change is not correct enough. I guess I do not know enough to do the right modifications. With huge size of pages, probably many part of the sourcecode of the kernel need to be modified, I guess. Has anyone succesfully using the 386BSD with larger virtual space per process than just 32MB ? What is the logical limit of the virtual memory size per process of the currect implementation of the 386BSD system ? I would like to know. Oh please, if anyone know the right way to expand the limitation, please post the direction. Than you. Hiroshi Murakami mhiroshi@tansei.cc.u-tokyo.ac.jp
