Hi everyone,

I have recently installed prespec code on the server I use for the data analysis. It works fine but I received a lot of messages concerning the buffer. An example of output message is here:

/data/avigo/62Fe_ag63_1081.lmd
opened plugin libprespecLYCCA.so
trying to open file /data/avigo/62Fe_ag63_1081.lmdcheck header: swap=0, header=1, buffer=0, size=32768
Check buffer: swap=0, header=1, buffer=1, size=32768
Read header again, 32768 bytes

and so on....

may I ask you if this is a problem for the sorting and how could I solve it?

thanks in advance for the help,

cheers,

Riccardo

Hi Riccardo,

this is no problem for the sorting. It is just polluting the terminal with text.

If you want to get rid of it, you have to remove 2 lines (line 2070 and 1001 in the file
eventapiV50/f_evt.c

2069 l_temp=read(ps_chan->l_channel_no,pc_temp, ps_chan->l_io_buf_size);
2070 // printf("Read buffer %d\n",l_temp);
2071 if(l_temp == 0) return(GETEVT__NOMORE);

1000 if(ps_chan->ps_bufhe->l_dlen <= MAX__DLEN)l_used=ps_chan->ps_bufhe->i_used;
1001 // printf("Buffer: %d words\n",l_used);
1002 ps_chan->l_buf_posi = ps_chan->l_io_buf_posi + sizeof(s_bufhe);

Then recompile the eventapi and recompile prespec.

Hi everybody,

I was trying to download the last version of the code, so I did:

- agatagsi@lx-pool.gsi.de:git/prespec
- ./configure --prefix=$HOME --with-gsievt-lib-path=/home/boso/prespec/eventapiV50 --with-gsievt-include-path=/home/boso/prespec/eventapiV50
- make install

I set the environment variables; I check and I have /home/boso/lib in the LD_LIBRARY_PATH

Everything seems fine; but when I launch the code I get the following errors:

cannot open module file "libprespecLYCCA.so": /home/boso/lib/libprespecLYCCA.so: undefined symbol: GOMP_parallel_end
module file is not open
ERROR: Controller config: In file ./Daq/unpack_user.config line 22: library LYCCA has no unpacker with name v830

...

and so on..

So it is a problem related with GOMP_parallel_end which doesn't permit to load the libprespecLYCCA.so library; it seems OpenMP was not properly linked during the compilation, or something similar; do you have any ideas on how to fix it?

Thank you,
Cheers,

Alberto

Hi Alberto,

some time ago I used OpenMP to make selfcalibration of DSSSD faster on multicore machines.
I removed this now since it seems to causes problems one some systems.

You can pull again. The error should be gone.... post again if not
