<div dir="ltr"><div><div>Hi Silvia,<br>Sorry it took so long to get back to you. It seems the problems you are seeing come from the cernlibs. I have tested some very basic simulation using gsim_bat but I would like you to verify that this works for you.

<br>ssh ifarm1102 # <-- this is the only rhel6 interactive node<br><br>source /group/clas/builds/test3/environment.csh<br>

Hello Dennis and Johann,<br>
last week I sent the email below to the clas_offline mailing list, but so far I had no reply. So I am retrying, sending it only to the two of you :-)<br>
<br>
I am quite concerned - but maybe it is just because I have no informations on the actual situation - about the transition of the farm to centos62. If all nodes are going to be replaced by the early fall (this is what I understood, I'll be glad if you correct me if I am wrong) we do need to have running executables for all the "standard" CLAS analysis and simulation codes, mainly GSIM, user_ana, and gpp.<br>
<br>
If this is not achievable, for reasons that are beyond my very little understanding of computing, compiling and the like, we should probably ask Computer Center not to replace all farm nodes, to leave things how they stand now or at least to leave enough nodes with the centos52 machines for us to be able to run jobs of CLAS6 analyses.<br>
<br>
I think this is an important issue that doesn't concern only my group (still heavily involved in CLAS6 analyses, with PhD students and post-docs, at different stages of advancement), but I presume most of the CLAS collaborators.<br>
<br>
Could you guys please give me an idea of the actual situation, and the next steps? Or, if there is actually no problems and the codes can be compiled fine, could you please tell me how to do that?<br>
<br>
Thank you very much and best regards,<br>
<br>
Silvia<br>

Subject: compiling/running gsim on centos62<br>
<br>
Hello, I have been trying to compile and run gsim on centos62, without success.<br>
<br>
I first tried the available executable in the "official" bin directory, but it crashes with a segmentation fault.<br>
<br>
I then checked out from svn the latest gsim and tried to compile it. The gsim packages compiles fine (both at 32 and at 64 bits), but errors arise when compiling gsim_int and gsim_bat. I tried at 32 bits first (problems of missing libraries, then once I found the right paths to the libraries there were errors related with gfortran...) and at 64 bits (all cernlib-related errors, which didn't go away no matter which available path to cernlibs at 64 bits I tried).<br>
<br>
As there is soon to be the migration of the farm to centos62, and several analyses of 6 GeV data are still ongoing, it would be really good if we could have some tips on how to produce working executables of all the "classic" 6-GeV codes (gsim, user_ana, gpp,...) on centos62.<br>
<br>
Every suggestion or offer for help is more than welcome.<br>
<br>
Thank you very much and best regards, Silvia<br>
