I have tried this with using ext3 partition, but I got lot issue with CPU utilization (waiting for io was more because of NFS). So I didnot seperate it. >Your client machines will use their own local ram and X resources >while executing.

However given that the cheapest mobo u can buy now is a via >cle clients should not be a problem. They have computers which are donated by people so I can't say that they will buy new 50 systems or not. Maximum client systems are i386 with Pentium 1 and 64 MB RAM.

We are running Tally7.2 Linux version on Server so noissue with that. But it eats up lot memory (Near about 50MB per instance). >group similiar hardware and describe each group in detail. >If you have wildly varying hardware, your nfsboot will be difficult to >maintain. If you want to use local resources you need 256MB ram Yes they have widely varying hardware as all PCs are donated by people. But almost 90% PCs are Pentium 1 with 64 MB RAM. And currently I am booting up them with LTSP-4.2. So no problem in thinclient system. But is it possible to get collective output of n number of PCs ? For example: If my server requirement is 3 GB RAM and 3 Ghz CPU. Then instead of bying one server of that much capacity, can I use 3 i386/586 PCs each of 1 GB RAM and 1 Ghz CPU ?
