I've been animating my fractals with fractint using *.bat & *.par files created by "proggies" like batcher, fae, etc.... Even though I'm trying to use distributed processing, ie., a "main.bat" type file that "calls" other "sub.bat" files, I've noticed that when I gnerating large batches of several thpousand images with fractint, the batch processing starts off pretty smooth and quick but, as the job progresses the batch processing gets slower and slower. Is there any way in writing the batch files that I can stop the "slowing down" and speed things up at bit? Would memory be a factor? Is there some kind of memory leak? I've allowed 8196K for XMS, 8196K for DPMI, I also checked HMA, and checked "protected" in the "convetional memory" settings for the "DOS Box" that's running the bat files. Should I allocate even more memory? Is there anything erong with the settings? What other settings should I be looking at? Does command.com use EMS? Should I be allocating memory to EMS? Ideas Anyone??? Is there something in the way I'm writing the *.bat files? I'm using "call" statments to call other smaller *.bat files. For example: ECHO OFF CALL 5SP001.BAT CALL 5SP002.BAT CALL 5SP003.BAT CALL 5SP004.BAT CALL 5SP005.BAT CALL 5SP006.BAT ........ etc. Then those *.bat files in turn call fractint and *.par files: FRACTINT @e:\fract\par\5sp001.par/Step0 BATCH=Y IF ERRORLEVEL 2 GOTO END FRACTINT @e:\fract\par\5sp001.par/Step1 BATCH=Y IF ERRORLEVEL 2 GOTO END FRACTINT @e:\fract\par\5sp001.par/Step2 BATCH=Y IF ERRORLEVEL 2 GOTO END FRACTINT @e:\fract\par\5sp001.par/Step3 BATCH=Y IF ERRORLEVEL 2 GOTO END FRACTINT @e:\fract\par\5sp001.par/Step4 BATCH=Y IF ERRORLEVEL 2 GOTO END FRACTINT @e:\fract\par\5sp001.par/Step5 BATCH=Y IF ERRORLEVEL 2 GOTO END FRACTINT @e:\fract\par\5sp001.par/Step6 BATCH=Y IF ERRORLEVEL 2 GOTO END .........etc....
