What memory is available for memory mapped files? Is it: (1) All of the physical memory and swap space? (2) Just the physical memory? (3) The amount of space [physical [plus swap?]] not being used by other processes? We run numerical simulations that use nearly all of the physical memory -- and then some. Does this mean the memory available to coda is thus limited? In previous messages the question seems highly specialized and I am not an expert in this matter. For example, in a message > Subject: Re: rdsinit death > Date: Mon, 31 Jan 2000 15:27:32 -0500 it was written: > It could be that there is not a big enough chunk of memory available in > the memory map around the address that we try to mmap the data segment. > Try to figure out where shared libraries and such are mapped.

I realize that the WWW site of coda emphasizes that the software is at beta level. Nonetheless, asking users to study the situation as described above does not seem to be a reasonable direction for the development of the software. I have installed several dozen public domain packages and of all of them "coda" has given me the most problems. Alan Scheinine Email: scheinin_at_crs4.itReceived on 2000-03-30 03:24:46
