- Distributed.Net RC5-64/DES Client version 2.7100 updates.
-
- Thank you for downloading the Distributed.Net version 2.7100 rc5/des
- client. By installing this client, you will ensure that you obtain the
- most optimal performance you can obtain for the DES-II-2 contest on July
- 13th, 1998, as well as the most optimal performance for the ongoing
- RC5-64 contest. Please read this file in its entirety, as many
- noteworthy changes have been made, which may or may not affect you.
- Also, please check for any platform specific readme files that may have
- accompanied this client.
-
- There are many changes in version 2.7100 over 2.70x that you should be
- aware of. They are as follows:
-
- - Buffer file formats have NOT changed. You may use the exact same
- buffer files you have been using with your 2.70x clients. However,
- buffer files from 2.64x clients should be deleted before installing
- the 2.7100 client, as the format is different.
-
- - New contest switching logic has been implemented. 2.7100 clients will
- query the status of the ongoing contests during each connect to a
- keyserver, ensuring that your clients will switch to DES the first
- time they connect to a keyserver after DES has begun. Also, 2.7100
- clients will recognize which blocks were from DES-II-1 (some may still
- be sitting around in your buffer files), and skip them so that you do
- not waste time. With a 2.7100 client installed, all you need to do for
- DES-II-2 is to cause your client to do an update, flush, or fetch
- on July 13th, 1998, and it will start working on DES-II-2.
-
- - New DES cores have been implemented on all platforms. You will see
- speedups ranging from 50 kkeys/sec (on ppros) to 8 megakeys/second
- (on ultrasparcs). As a result, it is in the best interest of your
- keyrate for you to install new clients whereever possible!
-
- - A completely new config menu has been implemented. It now includes
- many more options that previously required .ini file editing to
- activate. The menu has been arranged so that in most situations, you
- will never have to configure any options besides the ones on the
- Required Options menu.
-
- - Two .ini / command line options have changed
-
- - Firemode. This option has been removed. All the functionality of
- firemode is in uuehttpmode. If you were using a configuration with
- firemode 0 or 5, you need to make no changes to you configuration.
- However, if you were using firemode 1 through 4, you should go into
- the configuration menu Communications Options and ensure that the
- firewall mode is set as you need it.
- - Preferredcontest. This option has been changed. The new option
- replacing it is processdes. Processdes is a 1/0 option. When it is
- set to 1, the client will participate in DES contests. When it is
- set to 0, the client will NOT participate in DES contests. The
- primary reason for changing this option was so that if you're
- upgrading over an old client (which may have changed
- preferredcontest back to rc5), you will not have to worry about it
- accidently not working on DES. Please make sure you change any
- references to preferredcontest to use processdes instead (described
- in rc5des.txt.)
- - You may also notice two new .ini settings, contestdone and
- contestdone2. These options are set automatically by the client to
- tell it which contests are currently ongoing. Please do not change
- these options.
-
- To maximize your DES performance, you should do two things:
-
- 1. Set your preferred block size to 2^31, instead of the default 2^30.
- Using 2^31 blocks will ensure that our master keyserver does not become
- overloaded, and will help make the contest smoother for all
- participants.
-
- 2. Make sure you keep a small amount of blocks in your buffers. We
- expect DES-II-2 to be a short contest, hopefully lasting less than two
- weeks. To ensure that your work is counted, and we make constant
- progress, please buffer only ONE DAY'S worth of blocks at any time. If
- your clients are on constant Internet connections, you should set them
- to buffer as few blocks as possible (1 sounds like a good number) so
- that there is as little latency as possible.
-
- Upgrade procedure(s):
- ---------------------
-
- If you are currently running a 2.70x client:
- 1. Shut down the currently running 2.70x client.
- 2. Move the new executible from the 2.7100 client into the place of the
- 2.70x client.
- 3. If you are using a firewall, please read the note about the removal
- of firemode= and ensure that you are not adversely affected by it.
- 4. Start the new client up, you're ready to roll!
-
- If you are currently running a 2.64x client:
- 1. Make sure to flush any finished blocks out of your current client
- (rc564 -flush)
- 2. Shut down the 2.64x client.
- 3. Delete the 2.64 client, and its buffer files (buff-in.rc5, buff-
- out.rc5)
- 4. Move the new 2.7100 client into the directory the old client was in.
- 5. Start rc5des -config, and ensure that the required options are set
- properly. If you are using firewall support, see the section on the
- removal of firemode= and its consequences.
- 6. Start the new client up, you're ready to roll!
