And as for memory versus data files:  memory reads are around 3 orders of magnitude faster. So why not put all the data hard-coded in the program using DATA statements or other explicit initialization? Certainly for data that does not change over time this is something to consider.  For example, phase tables of water (steam tables) will never change over time (hopefully).  Good candidate for putting into a program in a table without...

The forums use a variant of the popular TinyMCE editor which does not include Fortran highlighting.  Just use "Plain".  I have asked that Fortran be added as an option, but it's a lot of work for not much benefit, in my opinion. -------- Steve Attaching or including files in a post Doctor Fortran blog @DoctorFortran on Twitter

Intel Forums have two subforums dedicated to Fortran but when using the code highlight tool when posting there's no option for fortran syntax... discrimination against the language? -------- Ricardo Reis 'Non Serviam' @ Lasef @ Rádio Zero @ volunteer work in aircraft restoration @ flickr

Wow, very interesting.  That explains the fact that my frustrated move of turning everything into static arrays did not help at all.   They don't call it the curse of many dimensions for nothing... time to turn this project over to the supercomputer, I think. One other question, if the answer is readily available: I frequently come up with questions regarding optimization for which I am probably not educated enough to design good...

Quoting - tim18 Is this the separately purchased IMSL?  It may offer support for 10.0 yet have a good chance of working with 11.1.  At the price, I wouldn't blame you for wanting more assurance, yet you could give it a try first. IMSL provides several functions that are not provided by the Math Kernel, such as gamma function, inverse CDF functions. The salesman from VNI (vendor of IMSL) told me that the current IMSL for linux is not...

Quoting - tim18 Unfortunately, if you want to make procedure arguments strictly compatible with f95 and f2003, you must use external procedures. Hi Tim, Thanks for the suggestion. Unfortunately indeed, but if that's the only way to get the code to run... Best, Grgur

Hi, I recently started a post related with this instruction, about HOW exactly use that instruction because in older versions of the compiler and a linux-based machine it works well. But now, I am working on two Mac OS machines, each one with different versiones of the compilers and I am not able to use -mcmodel. For version 11.1.058 the error message is: "ifort: command line warning #10152: option '-mcmodel medium' not...

Hi, I decided after a while that using the debugger idbc is not a bad way to debug fortran apps. My trouble is to set breakponts for subprograms from modules. (I could do it in the past and that is very annoying). at the moment I grep for the symbol name in the binary and I set the br on it (works perfect). I would like to go back to my old ways when used to do br mod_name::sub_name Alin
