Dears,
Please could someone help me with my UDF issue. I build this code that reads velocity values and time from .txt files, storage the values in vectors and uses the values as input on time dependent boundary conditions (Coordinate U and Coordinate V). The code works in a PC with Windows system with no problem, but I need it to run it in a cluster with Linux system. I got the case, UDF, and the three files in a folder, and when I click on BUILD I got some warnings but, the libudf folder is created. However, when I click on LOAD, I get this error: Code:
Error: received a fatal signal (Segmentation fault). Error: received a fatal signal (Segmentation fault). Error Object: #f please if anyone could help me solve this issue, I would appreciate. Thanks. Log details: Quote:
Code:
#include "udf.h"
#include <stdio.h>
#include <math.h>
int n=24;
real *ttmm;
real *uvelocity;
double hr=10;

Test if your files can be opened...
Code:
uvel = fopen("U_velocity.txt","r");
tm = fopen("time.txt","r");
if (!uvel) {
Message("U_velocity.txt" could not be opened.");exit(1);
}
if (!tm) {
Message("time.txt" could not be opened.");exit(1);
}

Hi Pakk,
Thanks for the reply. I have tested with the routine you sent me, and looks like files are actually not being opened. Thats might be why the warning is about the fscanf. The information on the console shows the message that the file is not being opened. Do you know if there is something wrong? I am not an expert using UDF or programming, but maybe could have another way to open the files. Thanks again, I hope you guys can help me. Follow the logs bellow. Quote:

Thank you all for the help.
I made some modifications in the files name, and it worked. Now the Linux system is compiling the code, but only in serial. I am trying to adjust the code to run in parallel, and getting a bit of trouble. I read the manual, and I see that I need to include some compiler directives (#if !RP_HOST, #if RP_NODE, etc), but I still didn't get it right. I am new to using a parallel process, and I am not sure what process should be done by the host or by the node. If you guys have any suggestions of parallelizing this code, I would appreciate. Thank you in advance. |

to run your code in parallel you should modify read/write from file part
algorithm: 1. read from file to host 2. transfer read data to nodes 3. calculate on nodes 4. send back from nodes to host also you should modify loops commands was Code:
begin_f_loop(f, thread) { ... } end_f_loop(f, thread)
Code:
begin_f_loop_int(f, thread) { ... } end_f_loop_int(f, thread)

Thank you for the suggestions @AlexanderZ, I am working on the parallelization of this code, that's the first time I am working with parallel UDF in a cluster.
I still didn't figure out the proper way to organize the compiler directives. Also, I am using the command host_to_node to send the array of uvelocity, vvelocity and ttmm(time) form the ON_LOAD function to the DEFINE_PROFILE. I don't know if it's the correct way to use that. I still have a few questions. 1) On step 3 of the list that you made @AlexanderZ, what exactly should I consider calculation on this code? should I put the #if !RP_HOST for all the DEFINE_ PROFILE macro? 2) On step 4, what should I send from node to host? I still don't get it? I am posting the code here if you guys could help me parallelizing this code, I really would appreciate. I'm running out of time on my project and I need to get this UDF working on our cluster. Thank you all. Code:

first of all, I looks like you have problems with permissions
Code:
Node 0: Doesn't have write permissions for libudf/lnamd64/3ddp_node. unfortunatelly, I have no experience working on linux. on the other hand Code:
DEFINE_ON_DEMAND(list_velocity)
{
#if RP_HOST
int i=0;
int j=0;
for(i=0;i<n;i++)
{
Message("\nVelocity_U[%d]=%.2f\n",i,uvelocity[i]);
Message("\nVelocity_V[%d]=%.2f\n",i,vvelocity[i]);
Message("\nTime[%d]=%.2f\n",i,ttmm[j]);
j++;
}
#endif
}
regarding step 4. it is needed in case you want to write into file. best regards |
