WMPI is available at: http://dsg.dei.uc.pt/wmpi For direct information about new releases and other news of WMPI subscribe to We will try to answer any queries and suggestions we receive at the e-mail address . --------------- The WMPI v1.2 has new features and bug fixes: -In the previous version the amount of shared memory available for local communication was fixed at startup. Many users were confronted with an error saying that the system had run out of shared memory. With this version the amount of shared memory used is variable and increases to fill the user's needs. So users don't have to change the amount of shared memory (with the option -p4gm) if they intend to send huge messages between local processes. Note that for max performance it is best to allocate all memory at startup and switch off the dinamically allocation shared memory (with the -gmstatic option). -This version is compatible with the MPICH1.1.1 version. -Workers executable path was increased, in this version, from 100 characters to 200 characters. -The MPI_WTICK and MPI_WTIME precision was improved from one milisecond to one microsecond. -In the console version, the settings of the users are not changed anymore. In the former version the foreground settings were changed to green, now the settings are not changed. -The WMPI core was changed for dependability, solving all reported errors. --------------- Best Regards, Hernani Pedroso ~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=-~-=- Hernani F.
