Hello all,
I met a problem in running REMD.
I'm using amber8 installed on Intel Xeon clusters (dual core).
After I found that test REMD runs using 16 replicas on 4 nodes were successful for at least 1000 exchanges,
I tried to run the same job using 32 replicas on 8 nodes.
After just 4 exchanges, the job stopped giving the following error messages.
These are a few lines at the beginning of the error messages.
.....
*** glibc detected *** double free or corruption (!prev): 0x00000000016f2600 ***

.....
Please let me know what is the source of the error in this case.
Thanks for your answers in advance.
