James, I have fixed the problem you found in Pelegant 23. It will correct the result from the CSRDRIFT element for fiducial beam tracking. You can try to use the attached file (put it under elegant directory) to fix the problem before we have next formal release. For fiducial beam tracking, all the ...

Did you turn off the ISR? I didn't see it in your template file.
&alter_elements
name=*
type=CSRCSBEND
item=ISR
value=0
&end

If the problem is still there, can you provide the nlsl_0p2nC_schic_m4.lte, so I can reproduce the problem.

Thanks,

Yusong

Thanks for reporting the bug. We have found the problem when first_is_fiducial is set to 1, and try to provide a fix for the next release. Our test with less number of particles doesn't crash as the memory read illegally was not used. For a larger test, it will crash. The serial version of elegant s...

I am afraid the AFS is not supported. "Supported file systems are IBM PIOFS, Intel PFS, HP/Convex HFS, SGI XFS, NEC SFS, PVFS, NFS, and any Unix file system (UFS)." The reason is the last process to close file overwrites the updates of all the other processes on AFS. Pelegant is designed for high pe...

It is not supported to compile Pelegant with non-parallelized I/O. First, make sure you compile the SDDS/SDDSlib with "make clean; make MPI=1" (The desired version of mpicc should be in your $PATH); then do "make clean; make Pelegant " under the elegant directory. If the problem still exists, you mi...

The most recent version of Pelegant can ONLY be used with parallel SDDS . Some extra steps need to be done after compiling SDDS from source code: 1) go to SDDSlib directory; 2) make clean; 3) make MPI=1; These will generate the correct version of SDDSmpi library to build Pelegant. I don't have a sys...

I can also get output files with your input files on my laptop. It could be an MPICH2 setup/usage problem. Please refer to the following document for your Pelegant installation/usage http://www.aps.anl.gov/Accelerator_Systems_Division/Operations_Analysis/installationGuide_Pelegant.shtml Make sure th...

The centroid output file should only be written by one process. Can you provide more information about the MPICH setup (version, daemon), Pelegant (pre-build version?) and operating system. It will be very helpful if you could provide a simplified lattice/template to reproduce the problem. The MPICH...

I have successfully built and run Pelegant (22.01) with SDDS (2.6) on my dual-core Linux laptop with the latest version of openmpi (1.3.2). Both result and speedup are reasonable. A couple of things you can check: 1) "In general, Open MPI requires that its executables are in your PATH on every node ...

Pelegant does require the input SDDS file in binary format partially because the offset calculation for parallel I/O. On the other hand, Pelegant is designed for large scale simulation, binary data is more efficient and occupies less disk space. Under SDDS/SDDSlib directory, make clean; make MPI=1; ...
