GPU72.com TF worm fetching tool now available

[swl551]

Overview:
Over the past few months I received many requests to add GPU72 work fetching to MISFIT. I have also seen other threads in the GPU72 forum asking the same thing. Since Challsal has been insanely busy with real life work we agreed that my authoring of a simple HTTP POST type utility is a useful solution until he has completed his PrimeNET style API. Development was recently completed, and several persons participated in a closed beta test cycle.
For flexibility I built it as a console application thus allowing it to be executed by MISFIT or independently scripted by your hand. Additional flexibility was designed in where the program takes a single command line argument which is the configuration file you want it to utilize. The benefit of this is you can have as many configurations as you want where each configuration file fetches work with different parameters.



GPU72WorkFetcher.exe is written in C# against .NET 3.51 and compiled in Visual Studio 2010. A compiled version and full source code are available.


Key Features:
Single .EXE with no install required and only 13kb.
Configurable parameter file controlling all the possible values GPU72 allows when getting assignments
Implements the “.LCK” file locking mechanism found in by MFAKTO and MISFIT
Exit codes for robust scripting
Available source code for persons inclined to further customize it
Logging of HTML stream from each run

Configuration file values:

StagingFile: file_receiving_assignments (created if not exist, appended if exist)
ReloadWhenBelow:100 (threshold determines when Staging File needs to be reloaded)
FetchCount:50 (how many assignments to request from GPU72)
Low:0 (optional range low value)
High:100000000 (optional range high value)
Pledge:73 (will factor to)
#OPTION (type of TF assignments you want)
#WhatMakesSense = 0
#LowestTFLevel = 1
#HighestTFLevel = 2
#LowestExponent = 3
#OldestExponent = 4
Option:0

ReplaceNAwithDate:true (replaces Factor=N/A with Factor=YYYY-MM-DD )
URL:https://www.gpu72.com/account/getassignments/lltf/ (what page on GPU72 to fetch from)
UserID:ABC (GPU72 user id)
UserPWD:XYZ (GPU72 password)


How to get started:
1. Download GPU72FETCHER.zip from http://mersenneforum.org/misfit/downloads/gpu72/
2. Unzip all files. MISFIT users should unzip into MISFIT directory
3. Edit the provided GPU72config.txt file with your credentials
4. Open a command prompt to where you unzipped the files
5. Execute the RunFetcher.bat and observe the results
6. For MISFIT users see screenshot on how to implement in MISFIT directly after step #5 works

Error Codes:
0: Fetching of work was not required because number of assignments in Staging File was >= ReloadWhenBelow value

1: Fetching was required and work was retrieved, parsed out, and stored OK

100: A fatal error occurred. See screen output for condition


Special thanks to the following for guidance, ideas and testing.

Scott-
My sincerely thanks, as well. I can now say, as have you, that Auto Submit works flawlessly.....along with all the other features which I have tried so far.

This application is fantastic. I recommend it to all Windows users here.

Thanks for your hard work! I logged in to let you know testing has been perfect, but I see you posted it already.

One question on this. I've been getting a 0 when everything works correctly and it fetched assignments?

If you are calling the fetcher from a batch file you are probably getting the result code of cmd.exe instead from the fetcher.exe. You may need to do something like

@echo off
my_nify_exe.exe
if errorlevel 1 (
   echo Failure Reason Given is %errorlevel%
   exit /b %errorlevel%
)

Being a MISFIT user you don't need a batch file. See screenshot 15 on how to configure.

If this does not help let me know.

I swapped to the new one a bit ago, but it hasn't run yet. It should report correctly the next time time it runs. Thanks.

As always, thanks We all appreciate it.

I may look at it, now that work can be received through GPU72; but I only have one machine doing TF and now only one mfaktc instance due to the release of 0.20, so it's easy to do it manually.

Tell me about it! 0.20 is cutting into sales of Misfit! . . I am taking this to the Judger!
