[erlang-questions] Tool for performace evaluation

[Muhammad Yousaf]

 My sorter:go have spawn only i.e 
go(I,N,M) ->
    spawn(?MODULE, main, [I,N,M,self()]),
    receive done -> ok end.
main(I,N,M,Parent) ->
    Pids = lists:foldl(
	fun(_,Ps) -> 
	    [ spawn(?MODULE,loop, []) | Ps]

anyway by doing spawn(percept, analyze, ["test.dat"]).

it works thanks

Muhammad Yousaf

.does your sorter:go involves creating a link? (using start_link, spawn_link, ... etc)if yes, I believe this might be a bug in percept, as it doesn't tag the result messages and doesn't use a selective receive
as a workaround, tryspawn(percept, analyze, ["test.dat"]).2011/6/5 Muhammad Yousaf <muhammad.yousaf@REDACTED>






Hi ,

I am getting the follow error while running percept:profile


(client@REDACTED)3>  percept:profile("test.dat", {sorter, go, [5, 2000, 15]}, [procs]).

Starting profiling.
ok

(client@REDACTED)4>  percept:analyze("test.dat").
Parsing: "test.dat" 
Consolidating...
Parsed 443 entries in 0.015602 s.

** exception error: bad argument
     in function  length/1
        called as length({'EXIT',<0.56.0>,normal})
     in call from percept:parse_and_insert_loop/5


and i am running Erlang R14B any idea how can i fix it and make it run?


Thanks

As a note, you can start etop in text modeetop:start([{output, text}]).

Try use -X option to your ssh command. Don't forget that X11 protocol

forwarding is also permitted in sshd configuration (X11Forwarding

option in sshd_config).
