<br>
Sorry for the documentation. README on ug directory shows how to run it.<br>
<br>
Could you try to do as follows:<br>
<br>
1. Make empty file fscip.set<br>
2. run as follows:<br>
fscip fscip.set blah.zpl -q<br>
<br>
Best,<br>

Also, is there a manual online somewhere that I can use?<br>
<br>
I am trying to run it like "fscip blah.zpl" but I think it's looking for a parameter file, and I<br>
don't know what one looks like.<br>
<br>
I looked at the "ParaSCIP" reference on the UG homepage, but it's more of a technical/research paper<br>
rather than a manual to use fscip.<br>
<br>
Just trying to figure out how to solve the program specified my ZIMPL file and split it across 4 cores.<br>

Thanks Gerald! I appreciate the help. I ran in to a slight issue building it on Darwin (mac)<br>
however:<br>
<br>
src/ug_scip/fscip.cpp: In function ‘int main(int, char**)’:<br>
src/ug_scip/fscip.cpp:306: error: ‘SA_NOMASK’ was not declared in this scope<br>
src/ug_scip/fscip.cpp:306: error: ‘SA_ONESHOT’ was not declared in this scope<br>
<br>
I was able to get it to build by adding the following to the top of fscip.c<br>
<br>
#define SA_NOMASK SA_NODEFER<br>
#define SA_ONESHOT SA_RESETHAND<br>
<br>
You probably want a cleaner solution than this, though, which is cross-platform compatible<br>
during build.<br>

Hi George,<br>
<br>
the PARASCIP compile flag is only used to compile SCIP threadsafe. If you want to use<br>
FiberSCIP you need to compile the ug framework supplied with the SCIP optimization suite<br>
(FiberSCIP is the ug framework applied to SCIP on a shared memory machine). From the main<br>
directory, run "make PARASCIP=true ug"; the FiberSCIP binary is than located in<br>
"ug-0.7.1/bin/fscip".<br>
<br>

Hi,<br>
<br>
I have a quad core machine and I would like to run SCIP using all 4 cores using the recent<br>
FiberSCIP work. I have scip opt suite 3.0.1 and built from the main directory using "make<br>
PARASCIP=true"<br>
<br>
I didn't find any documentation on how exactly things should work there forward (e.g., are<br>
flags needed?). But it appears that only one of my cores is being used, and the process<br>
manager suggested there was only 1 thread from scip:<br>
<br></div><div class="im">

Does anyone know how I can trigger FiberSCIP to split the work across the cores?<br>
<br>
Thanks!<br>
