有更多CPU的机器，可是IDL不能并行，有人有mpiDL的经验吗？
mpiDL值不值得买？ | G*******s

is built that way. You only have to enable it...
And, if your program has ENVI calls, just remember to set your IDL program
in windowless mode, will triple the speed easily. I write a lot of huge IDL
programs for global coverage, some run for weeks, but can all be optimized.

发帖数: 76 | 4 yes. you are right. IDL does have many( not so many?) build-in
paralleled routines. My default !cpu.tpool_Nthreads has always
been setted to 0. I dont have idea whats the approriate value
for TPOOL_min_elts.
everytime when i was so confident in my PROs, the output
result turned out to be wrong, after 2 days of helpless waiting.-_-
btw, one of my rules is, never call ENVI routine in IDL, hehe

I've helped RSInc corrected a dozen IDL/ENVI bugs since ENVI 3.5, but they
treated me so badly...they really do not have the respect to users as ESRI
has...

发帖数: 3728 | 7 IDL是好东西啊，处理坐标方便，数学函数不少，I/O超快，又可以调 EML,两者混合编
程非常适合地学大规模程序
