Hello, perhaps it's there but I can't find it... Is there a chess game on plan9? Thanks Ruda

Also, generally, there should be a quicker way. Ruda

Therefore I asked for a more specific pointer. Also, generally, there should be a quicker way. it's easy to blame the protocol. but it's more than that. 0. the i/o unit is just 8k, this means that directories like /sys/src/9 take 2 or more round trips. this is trivial to fix by upping MAXRPC in devmnt. i've uppted this to 56k + IOHDRSZ. this makes a difference even when the rtt is 50µs. 1. (or 0a) the kernel won't issue more than one concurrent rpc for the same request. 2. find/du are single threaded, so they they take full rtt latency on each syscall. there's a small demonstration of 2 at the end of this email. - erik --- note that except for the fcp test, rtt dominates. even 384kbps is more than enough to keep up. in fact, except for the fcp test time_link0 * rtt_link0/rtt_link1 tracks pretty closely with the actual result. since link1 is dsl, keeping track of the actual rtt could have reduced some of this error. link0: rtt ~ 32ms uplink/downlink ~ 100mbps/100mbps: 0.29u 0.37s 895.45r rc -c find | grep chess # status= find 7086421: errors| 0.03u 0.03s 68.77r rc -c cp lsr /tmp grep chess /tmp/lsr .0.04u 0.10s 5.40r rc -c fcp lsr /tmp grep chess /tmp/lsr link1: rtt ~ 52ms uplink/downlink ~ .384mbps/1.5mbps 0.00u 0.00s 1468.26r rc -c find | grep chess 0.00u 0.01s 131.03r rc -c cp lsr /tmp grep chess /tmp/lsr /dev/null 0.00u 0.00s 33.61r rc -c fcp lsr /tmp grep chess /tmp/lsr /dev/null

However, I do not really know how to proceed. It seems to me that contrib/steve/root/sys/src/cmd/mkmk/9port/gnu/chess is just some script whose use is one big unknown to me. Its purpose seems to be to create a mkfile and is probably intended to be run in a directory with gnuchess source (which is (?) to be downloaded separately). I have installed the mkmk thing using contrib/gui, downloaded the gnuchess source, extracted it, copied the chess script into it, ran it, but it produced quite a few error messages. Can anybody tell me what they did to get the chess program running? (Will there be a board as well?) Thank you. Ruda PS.: It's a pity there isn't such a thing like plan9 that would just work :)

Hello all, How do you play chess with plan9? I saw a gnuchess version in the games's man page of the first edition: doc.cat-v.org/plan_9/1st_edition/manual.pdf Any board also? Thanks in advance, trebol.
