BUGZILLA MRC PATCH

BUGZILLA MRC PATCH

Fixed incompatibility of the MOSIX kernel patch with kernel option 'CONFIG_HIGH_RES_TIMERS' (High Resolution Timer Support').

Fixed a bug in the -i flag of ' mosrun -E'.

With access to files exported from the caller's node. (not necessarily within the same MOSIX multi-cluster) MRC - A new program to run jobs on remote nodes.Refinement in choosing an initial process-assignment ( mosrun -b).Added the flag ' mosrun -g' for system-administrators that wish to limit/condition the use of mosrun.Fixed bugs in listen() and accept() (bugs were present only in 64-bit code).MOSIX may now start even when the MOSIX kernel-patch is not installed (or is of an incorrect version), providing minimal functionality such as ' mon' and ' mosrun -E'.New program - timeof, to find how much CPU-time a migratable process accumulated.Fixed a bug in queuing which reduced the dispersing of jobs in a multi-cluster.Fixed bug of missing SIGIOs in asynchronous direct-communication.Fixed a kernel bug that sometimes produced core-dumps (even after programs terminated successfully).Additional ioctl() functionality in direct-communication.The 'c' key in mon shows whether nodes have 32-bit or 64-bit systems.Support new security enhancements to open(), fcntl(), socket(), socketpair() accept().Support new system-calls: dup3(), pipe2(), preadv(), pwritev().Fixed a problem that could make mosrun get stuck when processes blocked too many (over 16000) signals.Fixed a bug in handling invalid addresses given to system-calls by faulty programs.Fixed a bug in statfs64() on 32-bit systems.Slightly improved initial-assignment algorithm.Improved performance of remote times() system-call.Support newer computers with more cores.Fixed a bug affecting migrations to distant computers and checkpointing.Fixed a bug that could affect process-migrations with.Added optional tools that allow the system-administrator to control.That option was now removed and is no longer necessary. 'Support for mixing compilers/architectures' was set. (gcc 4.4) and the kernel-configuration option Fixed a problem when the kernel was compiled with recent compilers.Support kernel configurations with 'Maximum number of CPUs'.Removed limits on the maximum process-ID, to support more cores.Last distribution that supports 32-bit and 64-bit architectures.Bugfix in the 'utimensat()' system-call.No longer supporting cluster-partitioning.No longer supporting the 32-bit architecture.

Changed default for 'mosrun -M' and 'mosbatch' to '-b' (select best node).No longer supporting tuning and topology.'mosps' differentiates between batch jobs and migratable programs with.Protected environment variables (formerly 'mosenv -E'). Separated 'mosbatchenv' from 'mosenv' for running batch jobs with.Separated 'mosbatch' from 'mosrun' for running batch.Improved performance of direct-communication.To move back home when evacuated from a remote node. Fixed a SIGSTOP kernel bug to allow migratable processes.Fixed bugs in setrlimit(ITIMER_VIRTUAL.) and setrlimit(ITIMER_PROF).A new method to determine processor-speeds.This release should work with all the 3.2 kernels up to 3.2.23.Bugfixes in freezing, checkpointing and Mostimeof.This distribution also supports Linux kernel 3.12.Fixed bugs in signal handling and the 'wait()' system-call.Last distribution that requires a kernel-patch.Batch and queuing by external packages such as SLURM.MOSIX-4 can run on any Linux kernel version 3.12 or higher.MOSIX no longer requires a kernel-patch.MOSIX Versions from now on have only 3 numbers (instead of 4).Fixed several bugs that occur when /etc is mounted read-only.Fixed a bug that occurs when '/etc/mosix' is mounted unwritable.

Fixed incompatibility with newer kernel (≥ Linux-3.16).

Warning against mixing Intel and AMD processors under certain.

'mosmon' shows number of cores (using the 'c' key).

Fixed a bug in 'mosctl' which occasionally kept the MOSIX.

Fixed bugs in aliases and allow aliases to nodes in the.

Reading correctly the load of threaded (non-MOSIX) jobs.

New facility for auto-detection of cluster nodes.

Bugfixes due to changes in the Linux 4.1 kernel.

Fixed a bug that caused 'mosrun mosmon' to freeze.

When CONFIG_NUMA_BALANCING_DEFAULT_ENABLED is configured.

Work around a kernel bug (bugzilla #1296505).

Overcome new restrictions imposed from Linux kernels 3.18.1.

Improved allocation when forking many processes.

Works with Linux kernel ≤ 4.7.8 and ≥ 4.9.9.

'mosmon' shows memory in GigaBytes instead of in MegaBytes.

Adjusted to recent changes in 'ifconfig'.

Adjusted to recent changes in glibc that hindered 'mosps'.
